Selecting The Prospecting Target Area By Multi-information

Areletuobie area is located in north of Qinghe County Xinjiang autonomous region. Its Structure position belongs the southwest edge of the Siberia tectonic plate, the main area is located on the Mineralization belt which has Rare metal,muscovite,Gold-Copper Ore and the Mineralization subbelt of Kanas Copper. Areletuobie area's Southwest corner entered into the Erchis gold Mineralization sunbelts. It is very well area for seek the metal mineral resource which contain tungsten, tin, molybdenum, copper, lead, zinc, gold, silver and so on.The natural condition is very difficulty and the fieldwork is inconvenient in the investigation area. For reduced the field work, this research analyzed Multi-mineral finding prospecting information in synthesis, such as geology characteristic, geochemical prospecting, and the remote sensing and so on, and selected the prospecting target area. The work process and the achievement as follows:1. Through to research the investigation area' geology characteristic and the mineralization rule, the geology prospecting symbol was established. According to the grid division method, the investigation area had been divided into7727 units. The total information of each unit was been calculated and drew the Isogram of prospecting symbol information.2. Dealt with the crude geochemical exploration data andrejects the extreme value. Then the correlation and R-type cluster analysis were analyzed. The tradition geochemical exploration (mean + n×standard deviation) method determines the lowest abnormal. The content Isogram of every element was drawn at last.3.Based on the principle of the remote sensing imagery and the characteristic of the Landsate7 multi- spectra data, the mineralization alteration information had been extracted through the method of PCA (principle component analyse) or classified by thresholds for the ETM+picture in the investigates area.4. According to the clue which provided by Multi-mineral finding information, the prospecting target area has been selected, then made a proof of geology.
