The western part and north belt of East Kunlun Mountain of Xinjiang is one of ourcountry’s important ore-forming district. It will make a lot of sense to mineral resourcessurvey and exploration when ascertain the types of mineral resources and theore-forming conditions in this district. This project is in the comprehensive study on theoutcome of regional geology and regional geochemical exploration in western part andnorth belt of East Kunlun Mountain. Optimizing1:500000geochemical prospecting forgold copper mineralization abnormal area and high anomaly area of Tula Regional tomake focus on study. Using1:100000geochemical exploration methods, delineatedgeochemical anomaly, emphasize to research anomaly characteristics and structurewhich particularly related with fracture structure, summed up the law, provide relatedinformation for searching metallogenic prospect areas. The plot located to the southernof Tarim-North China plate, Southern margin of qaidam micro continents QiMantageCariton fold system. The northern boundary is Arguin fault zone, adjacent with Arguinmarginal land; The southern boundary is Kunzhong fault zone, and connect with eastKunlun-south Qinling fold system, it is the hyperplasia belt of north China and southChina two plates. The above two fault zone was opening and closing many times sinceproterozoic, it makes the structure strong, frequent magmatic activity, mineralization isobvious, and is a good mineralization concentration areas.The district is located in QiMantage early Paleozoic magmatic arc with the western,northern and the southern margin of the Arguin fault, and south adjacent to vomit pulllate Paleozoic rift basin fancies. At the same time it is also the joint of the two tectonicunits, so the structure is very development, and performance is particularly strongfracture structure. Faulted structure in the area north of the west to the structure as theskeleton, more than ten large fracture structure is visible, they are in North Westdistribution, and for a parallel fracture group. Distributed in the contact zone or granitesand the formation are of the gold water group, the fracture group is large-scale, structure predominantly brittle, and plane is in slow wave. The whole piece of physics andchemistry which development in the extreme north extrusion is the biggest for the areaof the fault zone, the zone for the outspread part is of the regional major fault, within theareas is from five hundred meters to more than ten kilometers wide large extrusionphysicochemical belt, the belt is mainly composed of complex rock slice, carbonaterocks and basic volcanic rock composition, with the earlier formed analysis of the faultzone, the time should be the late Cariton or the inheritance activities before this. Groupin a word, the fault may be part of the fracture in Kunzhong, it may be formed in thelate Cariton and early Vanisee.Basic geological work in the area is weak, is currently only1:1000000ofgeological survey and the1:500000stream sediment survey results, so the geology inthe carboniferous volcanic rocks as an object, next to1:500000ore as the guide, on thebasis of the geological survey with1:50000stream sediment survey and determineprospecting target area. Key research overlapping parts of the carboniferous volcanicrock and fracture structure, North West to the east to the overlapping parts of the faultand abnormal geochemical exploration and remote sensing, in search of the goldencopper lead zinc mineral research plan is roughly in this paper: Through thecomprehensive analysis of the previous geological results, research on metallogeniccharacteristics of the region mineralization types and main ore-controlling factors;Classified study of metallogenic zones, evaluation of regional prospecting potential, andore-prospecting criteria and metallogenic regularity for each area is analyzed; Researcha particular area and adjacent area of exploration technology, including geochemicalgeophysical remote sensing three aspects; Optimizing ore-prospecting target areas, andmaking parts of a large scale geological and geophysical-geochemical prospecting andengineering validation method. Carboniferous Kara Milan river group in the districtwith Qinblackdom metal element enrichment zone parts overlap, the large area ofanomaly zone shows that the area has a useful element enrichment of ore-formingmaterial base; Kunzhong time level fault zone in the north west fault in intense activityarea, for the carboniferous volcanic intrusive provides a good migration pathway, aswell as a useful component of the migration of gas and liquid and locating ore-formingprovides a good space location; Of1:500000Au Ag Cu the geochemical anomalies inthe area of large area distribution, of1:50000remote sensing Mg-OH groups mineralanomaly distribution on the north west fault, shows the area of minerals such as copper lead zinc good prospecting foreground its ore-forming geological conditions and hasfound that wolves ditch copper polymetallic mineralization conditions are similar, alsoprovides a deposit prospecting ideas of the instance.All to physicochemical characteristics such as remote indicated the prospect goodprospecting in the area. Focuses on overlapping parts of the carboniferous volcanic rockand fracture structure, North West to the east to the overlapping parts of the fault andabnormal geochemical exploration and remote sensing, is expected to find gold copperlead zinc mineral prospect is optimistic.
