103 GEOCHEMISTRY AND GEOCHRONOLOGY OF HARIAMA ISLAND ARC GRANITOIDS IN BEISHAN AREA OF INNER MONGOLIA: Geological Implication
WANG Hui, ZHANG Huan, PAN Zhi-long, WANG Shuo, HE Jiao-yue, ZHANG Jin-long, HOU De-hua, MA Meng-ling, LIU Ya-fang
The Hariama island arc granitoids are outcropped in Gongpoquan island arc belt of Beishan orogenic belt, including diorite, quartz diorite, plagiogranite, tonalite and so on, associated with the arc volcanic rocks of Ordovician-Silurian Gongpoquan Formation. The LA-ICP-MS zircon U-Pb dating results indicate that the diorite (430.9±4.7 Ma) and tonalite(452.5±3.2 Ma) were formed in the Late Ordovician-Early Silurian. The petrogeochemical analysis results show that the granitoids belong to calc-alkaline, quasialuminous-weakly peraluminous I-type, with the Mg# value of 44.58-51.85, Rb/Sr ratio of 0.025-0.282, Nb/Ta ratio of 0.068-14.01 and Zr/Hf ratio of 13.05-34.00. The ΣREE+Y is 59.87×10-6-118.56×10-6. The right-dipping chondrite-normalized REE distribution curves reflect the LREE is enriched, with (La/Yb)N of 3.11-23.86 and unobvious Eu anomaly. The primitive mantle-normalized trace element spidergram reveals the enrichment of LILEs (Rb, Ba, Th, U and K) and medium incompatible elements (Ce, La and Hf), and depletion of HFSEs(Nb, Ta, P and Ti), with the characteristics of island arc granite, indicating the crust magma is mixed with magma from deep depleted mantle. Combined with other geological and geochemical evidences, it is considered that Hariama granitoids were formed in island arc setting, which is the result of northward subduction of Hongliuhe-Niujuanzi-Xichangjing paleo-ocean basin. The subduction began in the late Late Ordovician at the latest, and the ocean basin should be closed later than the Early Silurian.

118 SANDSTONE OF SIFANGTAI FORMATION IN THE WESTERN SLOPE OF SONGLIAO BASIN: Relation Between Hydrocarbon Fluid Characteristics and Uranium Mineralization
LUO Min, LI Jun-ye, LIU Xiao-hui, LU Sheng-jun
By analyzing the acidolysis hydrocarbon in 33 sandstone samples from Sifangtai Formation in the western slope of Songliao Basin, the paper discusses the composition, genesis and origin of hydrocarbon gas, and preliminarily analyzes the relation between hydrocarbon fluids and sandstone-type uranium metallogenesis combined with the geological characteristics of uranium mineralization in the area. The characteristic parameters of C1/ΣC, C1/C2+, C2/iC4, C2/C3, iC4/nC4 and iC5/nC5 for gas compositions in acidolysis hydrocarbon show that the hydrocarbon gas in the bottom sandstone of Sifangtai Formation is of organic origin, mainly in the maturity-high maturity stage, which are crude oil cracking gas and associated mixture gas, migrating to the bottom sandstone along superficial faults. The content of hydrocarbon fluids in uranium-bearing sandstone of Sifangtai Formation is generally increased, indicating the uranium mineralization is closely related to hydrocarbon gases. The place near the superficial fault connecting the bottom of Sifangtai Formation and oil-gas field is the key area for sandstone-type uranium deposit prospecting in the western slope.

126 LATE TRIASSIC ORE-CONTROLLING STRUCTURES OF PULANG PORPHYRY COPPER DEPOSIT IN YUNNAN PROVINCE
WU Lian-rong, ZHAI Jian-jun, YU Can, SHI Bao-sheng, LI Jin-lin, YANG Dong
Pulang copper deposit is of a super-large porphyry type in the eastern Yidun island arc polymetallic ore belt with frequent tectonic magmatic activities and significant superposition of fissure structure and ore forming-ore controlling conditions. However, the research degree is weak. Based on the comprehensive study of tectonic petrography of tunnels in Pulang copper orefield, combined with the regional metallogenic tectonic setting, the paper determines the macroscopic characteristics of folds and faults, and analyzes the joints/fissures in the typical levels. The results show that the mineralization of porphyry copper deposit during the closure of Paleo-Tethys Ocean is closely related to the Late Triassic tectonic evolution and magmatic activity, with Pulang copper deposit formed in subduction orogeny stage. The regional deep faults control the sedimentary formation and magmatite distribution in the orefield. The depositis is generally occurred in the core of Pulang antiform. The secondary NEE- and NE-trending faults control the development of ore-bearing porphyry and joints/fissures, while the ore/mineralized bodies occur at the junction of two groups of faults. The tension joint-dominated compound joint system provides passage and storage space for ore-bearing hydrothermal fluid migration, diffusion and enrichment. The development degree of fissures is positively correlated with copper mineralization. By studying the characteristics of magmatic intrusion-tectonic fissure system and ore-controlling rule in the orefield, it is considered that the hydrothermal vein ore/mineralized bodies are strictly controlled by the reformation and enrichment of tectonic and fissure system, and the site where fissure structure is well-developed is favorable target for vein ore prospecting.

136 GENESIS AND METALLOGENIC POTENTIAL OF THE PASIR ELA GOLD DEPOSIT IN CIKOTOK OREFIELD, INDONESIA
ZHANG Shun-yang, WANG Hai-bin, WANG Song, WANG Zhong-kai
The Pasir Ela gold deposit in the Cikotok orefield of Indonesia, tectonically located in Bayah dome in the middle of Sunda-Banda island arc, has the macroscopic geological precondition for finding large deposits. The ore-forming wall rock is the late Eocene-early Miocene andesite, with strong alteration and obvious zonation, in which several gold veins are occurred nearly parallel to one another. The deposit experienced 4 metallogenic stages, including quartz-smectite-chlorite, quartz-sericite-pyrite, quartz-adularia-sulfide-manganese bearing mineral and massive quartz. The gold deposit is genetically low sulfur epithermal type of oceanic island arc, with the subdivision of Pongkor-type banded low sulfur gold-bearing quartz-manganese oxide vein, and the hot spring type in the superficial part. It is concluded that the deposit has great deep prospecting potential and metallogenic potential of large gold deposits.

143 INFLUENCE OF SHALE COMPONENTS ON THE PORE DEVELOPMENT DIFFERENCES BETWEEN WUFENG-LONGMAXI FORMATION AND NIUTITANG FORMATION: A Case Study of JY-1 Well in Southeast Chongqing and CY-1 Well in Northwest Hunan
XIE Zhi-tao, HU Hai-yan, YUAN Hao-pu, LIU Ji-peng, WANG Tao, LIU Li-hang
Based on the accumulative pore volume and specific surface area by pore diameter of shale samples from JY-1 well of Wufeng-Longmaxi Formation and CY-1 well of Niutitang Formation, combined with the geochemical parameters and percentage of mineral components in samples, the paper analyzes the influence of shale components on the pore development differences between the two formations. The results show that TOC is positively correlated with micropores, indicating the organic micropores contribute to the development of shale pores, and organic micropores are more developed in the shale of Wufeng-Longmaxi Formation than that in Niutitang Formation. The positive correlation between quartz-pyrite contents and micropores indicates the primary pores and developed marginal pores contribute to the development of shale pores. The different correlations between quartz and meso-and macropores reveal the different protection degrees of quartz to the two by biogenic quartz content. The positive correlation between pyrite content and macropores reflects that pyrite can protect macropores to a certain extent in terms of pyrite content. The negative correlation between feldspar and pores shows the less obvious support of feldspar on pores due to the influence of compaction and complex structure. The unobvious correlation between carbonate minerals and pores shows the weak rigidity and instability of chemical properties and low content have no significant influence on pore development. Compared with Niutitang Formation, the high content of rigid minerals in the shale of Wufeng-Longmaxi Formation has a more favorable influence on the development of micropores (such as intergranular and marginal pores), mesopores and macropores. The negative correlations between clay minerals and micro- and mesopores indicate the intermineral pores easy to shrink under strong compaction have a negative effect on the pore development of reservoir, reflecting that the deep burial of Niutitang Formation has an unfavorable effect on the development of intermineral pores.

GAO Yong-zhi, CHU Yu, YANG Yuan-jiang
Taking the Luyang medium-scaled rock landslide in Huaihua City of Hunan Province as an example, on the basis of multistage high-resolution remote sensing (RS) data, the RS technology is applied to study the background factors of landslide geohazard. It is found that the Huaihua landslide is mainly caused by broken mountain and continual instandard mining. The results show that the RS technology can be used in the qualitative and quantitative analysis of landslide causes directly without exposure to hazard source.

ZHANG Shao-dong, LUO Wei-bin, WANG Liang, LIU Jiu-bo, LYU Zhi-bin, ZHANG Xiao-dong, CAI Jin-fu
Logging Technology has been being widely used in the fields of coal field, natural gas, freshwater resources, petroleum and solid minerals, which has gained lots of achievements and experience, but it is seldom used in the exploration of deep brine resources. By studying the logging results of many projects such as "Exploration of Mahai Deep Brine Potassium Deposit in Lenghu Town of Qinghai Province", the paper summarizes the characteristics of parameters including laterolog-3 resistivity,natural gamma-ray, sonic differential time and spontaneous potential in Cenozoic strata, and finds the common logging method being an indispensable guide to the exploration for salt lake resources, particularly for deep brine resources. The relation between characteristics of logging curves and single well sequence is found through statistical analysis of large amounts of logging data in the basin. Then the quantitative recognition is used to analyze and verify the parameter range and curve characteristics of natural gamma-ray and sonic differential time, and the logging interpretation method suitable for deep brine exploration in Qaidam Basin is summarized finally.

173 COMPOSITIONS AND VARIATION RULE OF SOIL CARBON POOL IN THE COASTAL AREA OF WESTERN LIAONING PROVINCE
WANG Cheng-yu, LI Yu-chao, GUAN Xu, WANG Yi, HAN Yan-hong, YU Yue, YANG Bing-bing
Based on the surface and deep soil carbon content data obtained from multi-objective geochemical survey in the coastal area of western Liaoning Province, the paper calculates the soil carbon density and storage in surface (0-20 cm), middle (0-100 cm) and deep (0-180 cm) layers of the study area, and discusses the compositions of soil carbon pool (SCP) and carbon sequestration potential(CSP) in terms of classification, as well as the variation rule of soil organic carbon (SOC) in the last 40 years. The results show that the SCP is dominated by organic carbon, while the inorganic carbon storage increases with depth, with the soil organic carbon density(SOCD) of 2.14, 7.59 and 11.27 kg/m2 for surface, middle and deep layers respectively, lower than the average of national multi-objective survey areas and circum-Bohai Sea area. The compositions of SCP vary in different classifications as follows:The carbon density of Proterozoic and Mesozoic units is high in surface layer, while that of Paleozoic unit is high in middle and deep layers; The soil carbon density of mountain is higher than that of hills and plain by landforms, the highest in cinnamon soil and the lowest in moisture soil by soil types, the highest in forest and grass lands and lower in cultivated land and garden by land use types. The CSPs of surface, middle and deep soils are 33.91, 103.32 and 129.37 Mt, respectively, with CSP of organic carbon higher than that of inorganic carbon. The SOC was increasing generally in the last 40 years, among which the surface soil of cultivated land and garden showed carbon source effect, releasing 0.29 Mt of SOC. The distribution of brown soil and forest land contributes the most to the input of SOC.

193 EVALUATION OF GEOHAZARD SUSCEPTIBILITY BASED ON INFORMATION METHOD: A Case Study of Wushan County in Chongqing Municipality
WEN Jin-mei, YANG Long, GOU Jing, LI De-long, WU Tao
Taking the Wushan County in Chongqing Municipality as object, the paper analyzes the characteristics of geohazards and influencing factors which include the topographic conditions, engineering geological rock formation, geological structure, slope structure, water level of the Three Gorges Dam and other human engineering activities. Based on information method, the ArcGIS software is used to extract and calculate the spatial information of each factor to get their contribution values to geohazards, and divide the susceptibility into ultra-high-risk, high-risk, middle-risk and low-risk areas. The occurrences of geohazards in different areas are counted respectively. It is found that the higher the susceptibility is, the more the geological disaster points there are, which is basically consistent with the actual situation, with good fitting degree. The result can be used to evaluate the susceptibility of geohazards in the same type of areas.

LI Xiao-song, FAN Wen, CAO Yan-bo, QUAN Zhuo-liang
Through the investigation on the basic geological characteristics of Yanjiagou landslide in Shanyang County of Shaanxi Province, the paper obtains landslide elevation data by means of drone, and establishes a MatDEM-based 3D discrete element model of the landslide movement and accumulation features, which restores the whole process of landslide occurrence and gains the characteristics of movement velocity, sliding distance, and accumulation thickness. It is considered that the Yanjiagou landslide is of high-speed type. The landslide accumulation process is divided into three stages:accelerated collision→overall sliding→deceleration accumulation. The distribution of accumulation thickness shows a general trend of increasing first and then decreasing along the movement direction, reaching the maximum at the back of accumulation body. It is proved that MatDEM is feasible to simulate the landslide evolution process.

214 ELECTRON PROBE SPECTRUM ANALYSIS OF CHROMITE IN MENGYIN KIMBERLITES, SHANDONG PROVINCE
CHI Hui-zhong, WANG Da-qian, LI Jing-guo, WU Yue, LI Chun-ling, ZHANG Yuan-yuan, LIU Jin-xiu, ZHAO Mei-jing
Chromite is one of the main indicator minerals in kimberlite diamond deposit. Accurate content analysis of the chemical compositions such as FeO, MgO, Cr2O3, Al2O3 and TiO2 in chromite is the key for the naming of chromite, and significant indication for kimberlite diamond deposit prospecting as well. The electron probe spectroscopy is used to analyze the major chemical elements in chromite, and the micro-area chemical analysis of measured samples to infer the mineral name. The analysis results of 25 single mineral samples show that the contents of major chemical components are 15.666%-29.971% of FeO, 7.286%-11.477% of MgO and 56.421%-71.111% of Cr2O3, with minor chemical components MnO 0.012%-0.382%, Al2O3 0.871%-8.993% and TiO2 0.074%-3.375%. The total mineral chemical composition is 99.117%-100.877%. The chemical composition of single mineral is equivalent to that of chromite. According to the mineral characteristics by artificial heavy mineral identification and positions of ion groups A and B, it can be determined that the measured sample is magnochromite.
