THE GEOPHYSICAL AND GEOCHEMICAL METHOD ARE VSED TO RESEARCH FOR THE COMPLEX ORE DEPOSITS ZONE IN XINJIANG

Xu Baoci Zhang Guibin Li Chunhua Meng Xiaohong  
Basing on the magnetometric end gravimetric data over the HM-76 region in Xinjiang, where the researches for metallic ores are specially concentrated, we had pretreated the original data by means of the compensated and smoothed filtering method, and done correspondence analysis between magnetic anomalies end gravity anomalies after separating the shallow sources field from the deep sources field.The reversed negative magnetic anomalies were polarized by using the program improved. The top and bottom depths of magnetic rock mass according to Specter and Grant theory had been calculated after completing the treatment and transformation of the data of anomalous fields.Then, we studied again the worked region by comparing the geological information with geophysical and geochemical data. Some new points of view on the geological problems of this region are given as following.1. The HM-76 region has the good geological condition for seeking the mineral deposits.2. The negative anomalies of the HM-76 region may be caused by self-reversed magnetization.3. The geological mainbody of this region may be a basificated and supper-basificated rock rod with vertical inclination and elliptic horizonal section.4. The HW-76 region may be the most favourable place for locating the mineral deposits.
