THE THERMOLUMINESCENT FEATURE OF QUARTZ AND ITS PROSPECTING AND EXPLORATIONAL SIGNIFICANCE IN WENYU GOLD DEPOSIT IN HENAN PROVINCE
Wang keyong, Wang Dehui, Fan Yongxiang
The study on the thermoluminescent feature of quartz in Wenyu gold deposit shows that obvious differences of thermoluminescent feature exist between gold-bearing quartz and barren quartz. The thermoluminescent curves of gold-bearing quartz possess weak single peak, the peak intensity is lower than 150cps and the total thermoluminescent intensity is lower than 10000cps. However,the thermoluminescent curves of barren quartz possess middle to high single peak, the peak intensity is usually bigger than 150cps, and the total intensity bigger than 10000cos. these indicators have great directing significance on exploration and e-valuating the gold-bearing feature of mineralized veins in this district.

THE FORMING CONDITIONS AND PROSPECTING SYMPOSIUM OF THE OXIDIZED ORE IN THE SUPER MICROGRAINED IMPREGNATION-TYPE GOLD DEPOSITS IN NORTHWESTERN GUANGXI
Guo Jiahui
This paper analysed geochemical habit of the gold in superficial oxidation zone,concretely studied conditions of oxidation leaching and enrichment and preservation of the gold in superficial oxidized zone of the typecal super micrograined impregnationtype gold deposits, which consist of:the characters of the orebody and ores, climate condition, elevation and denudation depth and emergence circumstances of the orebody, conditions of landform and geo-morphology and hydrogeology, develoment degree of the oxidation zone and type of oxidation shell, change factors on the shape and occurrence and thickness and gold tenor of the orebod-ies, and preservation of it. And 10 favourable conditions forming oxidition ores were summedup. Lastly, on the basis of these, it probed into prospecting for the oxidition ores of the gold deposits in this region.

THE STUDY ON METALLOGENY OF GAOLONG GOLD DEPOSIT, NORTH WEST GUANGXI
Li Li, Guan Guangyue
In northeast district of Guangxi,China,the micro-fine grain dissiminated type gold deposit is commonly distributed. Gaolong is one large scale gold deposit,which lies in the oxidization zone. The area lies in the south-eastern dectivity zone of Yun-Gui plateau. According to the deposit's geological characters, mineral's combination type and forming characters,the micro-fine grain dissiminate type gold deposits can be divided into two types as Gaolong and Jinya.
Gaolong type gold deposit is mainly distributed in oxidized zone (weathering belt). In the area,only oxidized ores are found, noevidence of primery sulfide ores. All bodies were yielded in oxidized zone. At the lower part of the orebody, only nonoxidized structured quartzite ore bodies be found. According to ore type,three types of ore bodies can be divided as follow:
a Texture quartzite type ore(keatite rock);
b siliceous texture brecciated ore;
c siliceous crushed crag ore.
Two experiment were done to know how oxidation effect original minerals under the dif-firent pH,teperature and bacterium.
Two types of the minerals can be devided into oxidized minerals and primary mineral (including pyritoides mineral, pyrite-arsenical type mineral, arsenical pyrite type mineral) According to the characteristics of the mineral's genesis and the mineral's paragenesis,we consider that Gaolong gold deposit is post-product in a cycle of metallogenetic epoch.

THE STUDY ON THE TYPOMORPHIC CHARACTERISTICS AND OCCURRENCE STATE OF GOLD IN SHAOGUOYINGZI GOLD DEPOSIT
Huang Fei, Zheng Chao, Wang jianguo, Zhao Chunfu, Ma mintao, Hao Hui
In this paper, the authors have studied completely the typomorphic charateristics of gold, such as minerology classification, morphological, grade, chemical composition and the purrity of gold, and the occurrence state of gold also have been studied, from the study, we can come to this conclusion; gold deposit is formed in medtemperatre, medium-deep condition, and it is magmatic hydrothermal gold deposit.

THE RELATIONSHIP BETWEEN THE LAMPORPHYRE CHARACTERISTICS AND GOLD MINERALIZATION IN QINBA MOUNTAIN AREAS
Tu Huaikui
The lamporphyre is Widely distribution in Qinba mountain areas, the agesare onacin Caledomian, Indosinian, yanshanian and Himalayan Most of the auriferous lam porphyre dike presented in palaeozoic and are mainly Devonian and Silurian and their wall rock are essentially repres ented by fine clastic rock. In this paper, the relation between the lamporphyre Char-acteristics and gold mineralization are discussed. It is suggested that structure fracture have played a very im portant part in diagenesis and ore formation. Alteration, assimilation Contamiation and oxidation of dikes enable the gold easy to activate, migrate, and enrich under suitable metallogenlc conditions.

POST PALEO-ISLAND ARC EPOCH TENSION ZONES AND MARINE VOLCANIC ROCK GOLD DEPOSITS OF BEISHAN AREA, GANSU PROVINCE
Cui Pluiwen
1. Post paleo-island arc epoch tension zones
The studied area was situated at the intersection of Tarim and Kazakhstan plates during early Paleozoic period. In late paleozoic (D
2
-D
3
), the south Mongolian ocean crust under-thrust form north to south, which resulted in the collision of the two plates with Siberian plate. The late Paleozoic area zone and back-arc-basins were formed, in the area, followed by a period of mid-plate tectonic activity. There were three extension-closure structure movements (O-S, C, and P), of which the third had the largest scale and strength, formed a large scale volcanic eruption and magmatic intrusion, and provided a favourite condition for gold mineralization. Four tension zones are recognized by study. They are; (a) Ganquan-Daqishan tension-depression trough; (b)Jinwozi tension-depresion zone; (c)Mazhuangshan-Nanjinshan tension-depression basin; (d) Baishan-langwashan rift zone.
2. Characteristics of marine volcanic rock gold deposits
The gold deposits of this area belong to marine volcanic rock type. The mineralization system is submarine volcanic eruption hydrothermal circulation system. For a nother type of gold deposit related to granitoid,its mineralization system is postmagmatic hydrothermal sys tem. The acid-intermediate to acid volcanic rocks and related intrusive rocks were formed in about the same time and associated spacially. Their REE composition, REE pattern and microelement characteristics are similar. Therefore, it is believed that the acid to acid-intermediate volcanic rcks and acid-intermediate granitoid in this area share the same material source and mineralization geology environment.
The marine volcanic rock gold deposits of this area occur in volcanic dome and volcanic sedimentray basin within the post island arc epoch tension zones. The ore-bearing stratum is lower Carboniferous Baishan formation. Hydrothermal alteration are mainly secondary quartzification sericitize and pyritization.
