CHARACTERS OF THE MESOZOIC BASINS AND THE BASIN-RANGE STRUCTURES IN WESTERN LIAONING
JIANG Shu-e, LIU Xiao-lin, ZHANG Guo-ren, PAN Yu-qi, LU Hong-feng
The Mesozoic continental basins and basin-range structures are well developed in Western Liaoning Province. The basins were formed in five stages, i.e. Early-Middle Indosinian (T
1,2
), Late Indosinian-Early Yanshanian (T
3
-J
1
), Middle Yanshanian (J
2
-J
3
), Late Yanshanian (K
1
) and the end of Yanshanian (K
2
). Generally, the basins express fault-depression in the early stages, while depression in late stages. The major axes of the basins trend NE or NNE, controlled by the tectonic frameworks then. The mountains (old uplifts) and wide basins in between combined the basin-range structures, which characterize the Mesozoic structure in Western Liaoning. The basin-range structures can be classified into Jurassic and Cretaceous types, showing multiple crust movements of fault-depression and extension during Mesozoic.

CORRESPONDING CHRONOGENESIS BETWEEN THE MESOZOIC METALLOGENY AND MAGMATIC ACTIVITY IN NORTHEAST CHINA
ZHANG Chun-hui, KANG Zhuang, ZHANG Guang-yu, LIU Ying-cai
With study on the chronogenesis of Mesozoic metallogenesis and magmatic activities in Northeast China, the chronologic framework of metallogenesis in Mesozoic era is established. The Mesozoic metallogenesis is centralized in two stages of 130-100 Ma and 200-160 Ma. The Mesozoic magmatic activities are chronologically subject to Late Mesozoic era, especially in the periods of 190-155 Ma and 135-115 Ma. There is a correspondence of chronogenesis between the metallogeny and magmatic activity in Mesozoic era.

BIAN Hong-ye, CHEN Man, LIU Hong-li, ZHAO Chun-rong
The Gaosongshan gold deposit of epithermal type is closely associated with volcanism. The ore is mainly goldbearing quartz vein and tectonic breccia-altered rock types, with sulfur compositions of deep source. The H-O isotopic compositions of fluid inclusion represent the mixture of atmospheric precipitation. The deposit is hosted in the Mesozoic Upper Cretaceous volcanic rocks, associated with dacite, andesite, andesitic porphyrite and rhyolite. The geochemical characteristics show a background of active continental margin.

CHARACTERISTICS OF ORE AND OCCURRENCE OF GOLD OF THE WANGJIAWAIZI GOLD DEPOSIT IN LIAONING PROVINCE, CHINA
FENG Xiao-yu, JIANG Fu-lun, BIAN Guang-qing
The Wangjiawaizi gold deposit is situated in the southeast of Yingkou City, Liaoning Province. The ore of the gold deposit is dominated by gold-bearing quartz vein type, with rich pyrite as main gold-carrier. The pyrite, closely related to gold mineralization in time, space and genesis, is the significant indicator for the metallogenesis of gold. The ore is in heterogranular and metasomatic dissolution textures and massive, dense massive and veinlet-disseminated structures. The gold minerals are medium-to fine-grained electrum and goldargentid in complicated shapes, occurring in fissures, crystal cracks and inclusions. The gold-carrying minerals include pyrite, galena, sphalerite, chalcopyrite and quartz. The deposit is characterized by metamorphic hydrothermal type. The multi-sourced mesothermal and meso-epithermal fluid is the major ore-forming factor.

TYPES, FEATURES AND GEODYNAMIC SETTINGS OF THE GOLD DEPOSITS IN ALTAY MOUNTAIN, NORTHERN XINJIANG
SHAO Hui-wenl, YANG Wei-min, CHEN YueI, DAI Qi-Dong
Two types of gold deposits in Altay Mountain, Northern Xinjiang are classified on the basis of metallogenesis, principal ore-controlling factors, mineralogical association, structure and texture of ore and nature of host rock assemblage. The two types involve orogenic belt gold deposit and epithermal gold deposit. The former is controlled by ductile shear zone and subdivided into two subtypes of gold ore (quartz vein type and altered rock type). The latter, controlled by volcanic structure and brittle faults, can be subdivided into high-sulfide and low-sulfide epithermal gold deposits. The high-sulfide epithermal gold deposits were formed in Carboniferous, corresponding to the Hercynian geodynamic setting of collisional orogeny. The orogenic belt type was formed in the Permian post-collisional orogeny stage. The low-sulfide epithermal gold deposits were formed in Mesozoic stable landmass stage.

GENETIC TYPES, GEOLOGICAL FEATURES AND PROSPECTING ORIENTATION OF IRON DEPOSITS IN EASTERN JILIN PROVINCE
JIN Yong-xin, YAN Shao-bo, LIU Chao
With a basic analysis on the metallogenic geologic settings, the genetic types and geological features of each type of iron deposits in Eastern Jilin Province are studied. Five types of iron deposits are recognized, i.e. sedimentarymetamorphic type, magmatic type, contact metasomatic (skarn) type, sedimentary type and weathered leaching type. Combined with the new progress in geologic prospecting, it is concluded that the studied area satisfies the essential geologic requirements for the metallogenesis of iron deposits. The iron resources potential in the area is great.

THE YANGJIAZHANGZI-BAJIAZI MOLYBDENUM-POLYMETAL METALLOGENIC BELT IN WESTERN LIAONING PROVINCE: Characteristics of typical molybdenum deposits and prediction for exploration
LIU Xiao-lin, FAN Ping, ZHENG Zhi-feng, LI Ai-li
The molybdenum deposits in the Yangjiazhangzi-Bajiazi molybdenum-polymetal metallogenic belt in Western Liaoning Province are closely related to Yanshanian acid-intermediate intrusion. The deposits that occur in the contact zone between granitoid and carbonate strata are skarn or porphyry-skarn type. The deposits hosted in granite-porphyry and felsic or intermediate volcanic rocks are mostly porphyry type of molybdenum deposits. The molybdenum deposits with different types share close spatiotemporal relations in genesis, distribution and zonation of ore-forming elements. The ore matters of the molybdenum deposits are derived from granite. The fine-grained granite is the parent rock for metallogenesis. Analysis on the metallogenic conditions shows a great prospect for exploration in the metallogenic belt.

HU Tie-jun, WEI Min, SUN Li-jun, LI Ji-cai
Chaihe Pb-Zn deposit in Tieling, Liaoning Province, occurring in the carbonate rocks in a sedimentary basin beside the central uplift basement in Fanhe aulacogen, is a typical epigenetic stratabound deposit. The Fanhe aulacogen, fault and fold structures, banded dolomite and breccia are main geological ore-controlling factors. The prospecting conditions include banded dolomite, geologic structures and karst breccia. The prospecting targets involve the areas above -300 m level and both sides of NE1 fault. The advanced geophysical exploration techniques should be adopted as tools for ore exploration.

DISCOVERY AND SIGNIFICANCE OF THE SHAGOU LEAD-ZINC DEPOSIT IN JIYUAN, HENAN PROVINCE
GONG Cheng, ZHANG Hai-yang
Based on the target delineated by geochemical anomaly, combining geophysical method, the Jiyuan lead-zinc deposit, which is similar to the Mississippi Valley Type(MVT), is found in the Upper Cambrian dolomite in Northwestern Henan Province. The orebodies, occurring in thick-bedded dolomite, are closely related to the horizons and structures. The intersections of structures with different times and various levels obviously control the formation of the lead-zinc deposit. With the analysis on the characteristics and prospecting signs of the deposit, the new exploration methods on such type of lead-zinc deposits are concluded, which provide some experiences for further prospecting.

is 0.64%. The vanadium ore is mainly psammatic type. Study on the diagenesis and metallogenesis shows that the Xincheng vanadium deposit is genetically formed by marine chemical or biochemical sedimentation, with also eluviation origin. The mineralization is strictly controlled by strata, lithology and rock facies.

ANALYSIS ON THE MULTI-YEAR VARIATIONS OF GROUNDWATER IN LOWER LIAOHE PLAIN
LI Kai, BIAN Yu-mei, YANG Jing, ZHANG Yi, ZHAO Ying
The dynamic variation of groundwater level is actually a reflection of the change of groundwater resources in aquifer. The fluctuation of groundwater level directly reflects the variation in amounts of consumption and recharge of groundwater. Based on the monitoring data of groundwater level, the variation characters of phreatic water in Lower Liaohe Plain from 1996 to 2005 are analyzed. It is concluded that whether phreatic water or confined water, the groundwater levels change along with precipitation in non-exploitation area and dry farmland area. Besides the contribution of precipitation, the exploitation scale and layout of groundwater in exploitation area are also significant influential factors for the variation characters of groundwater level.

FENG Yu-lin, XING De-he, CHEN Jiang, YANG Li-jun, BIAN Xiong-fei
The ore-controlling structure and ore-bearing stratum information is extracted by digital image enhancement processing. The information of mixed alteration anomaly is extracted with ratio logistic multiplication. The anomalous zones for mineralized alteration are delineated by the combination of the three kinds of information. Field investigation has proved that some of the alteration anomaly zones are in accord with iron diggings and a few gold-bearing mineralization quartz veins.
