Geochemistry Exploration Method And Techniques Of High-cold Hungriness Landscape In Southwest Of Tianshan Mountains, Xinjiang Area

High-cold hungriness landscape is the special landscape of physiognomy, which were mainly distributed in Xinjiang, Gansu, Qinghai and Neimenggu province. The proportion of this landscape exceeds 60 square kilometers and comes up to the 1/15 of the propotion of our soil. The climate of this area is dry, the monsoon is strong ,and the physical weathering is primary. The characteristic is similar to the geomorphy of stable block, and this area is becaming to the main producing area of mineral resources in the future, such as gold,silver,copper leadx zinc etc.This paper chooses the high-cold hungriness landscape as a subject investigated, and outspread the geochemistry prospecting method and techniques by the numbers. Our experiment plot lies in southwestern of Tianshan Mountain, Xinjiang area. A suite of geochemical survey methods including sampling distribution, sampling density, sampling grade, which are appropriate for geochemical survey in Gobi & hungriness, have been proposed through kinds of method testing in cross section and surface area in western of Tianshan Mountain area.According to the characteristics of this area, where the climate is dry, the evaporating capacity exceeds rainfall, the nondevelopment of the plant cover and the river system, and the more Aeolian sand, this test work was mainly aimed to generalize a suite of geochemical survey methods, and the test results indicats that the samples which were lie in ground surface (about 0～20 centimeter) is better while collecting sedimentary of river system. Meanwhile, the measure of several comparing rule have been proceeded to confirm sample medium. The results indicats that the detritus could clearly circle mineralizing anomalies with complete element association.In a word, we obtained good geological result of this paper with all sorts of methods we adopted to conduct the experiment. Through contrasting to the known orebody, the testing method is effective to disclose the unknown orebody of the area in high-cold hungriness landscape.
