| Under the current technical background, the remote sensing data precision enhancement causes the remote sensing geology information to have better macroscopic and microscopic, thus enable the remote sensing geology the resources investigation function to obtain the enhancement. At the same time, along with mineral resource unceasing mining and the consumption, the unknown minerals has lies concealed the nature, and the geological work degree low region often is following the difficult natural condition. Therefore, it is an important research direction of the current geological work to explore prospecting technology plan with remote sensing geology information extraction as the center of gravity.Laichau is our country gold production base, the gold productivity accounts for the national gold output 13.4%, and accounts for the Shandong Province gold output 52.7%. The extra large type gold ore deposit already discovered which in Laichau's has three: San Shan mountain islands gold ore deposit, new town gold ore deposit, Jiaojia gold ore deposit. The large-scale golden ore deposit has two: Wang'er mountain gold ore, Cangshang gold ore. The medium golden ore deposit has five: Hong Bu gold ore, Dongji gold ore, Ma tang gold ore, Sizhuang gold ore, Houzhao gold ore. And more than 20 mineralization points or gold ore spots have been found. This paper research work main goal is fully is analyzing the predecessor material in the foundation, and based on the geographic information system platform, utilizes the new geological theory, the new prospecting method and the method to the Laichau gold ore centralism area mineralization rule, the mineralization pattern conducts the comprehensive research and the summary, and thus carries on the mineralization forecast to the entire Laichau gold ore centralism area, seeking the depth portion, side, the flank blind ore body, in order to increase ore resources reserves, and lengthen the mine service life.The writer carries on processing to the Laichau area ETM remote sensing phantom data with application digital image processing method, and has obtained the good effect. She has withdrawn the mineralization alteration information and strengthened the loop of wire phantom characteristic. She has verified the golden ore deposit (body) was in the loop of wire structure connection, the junction cuts as wellas the ring structure edge spot. With the aid of in the remote sensing study information analysis method, the writer withdraws the mineralization advantageous loop of wire structure from the remote sensing phantom, and uses the mineral resource appraisal analysis system MORPAS software developed by China University of Geology to linear structure quantitative, gained massive quota information related with the gold mineralization.Moreover, the writer analyses fully prospecting information of remote sensing, geology, the geophysics and geochemistry. She has fully used the spatial analysis function of MAPGIS and resource information system platform to withdraw each kind of information which relations closely to the mineralization, and calculated each kind of mineralization information using the conditional probability law to the mineralization contribution. She has calculated the sum total of various grids unit the information content. With certain information value(3.5), eight ore-searching areas are drew: Ai (new town and Jiaojia gold mining area periphery and depth portion), A2 (San Shan islands - Cangshang golden mining area periphery and depth portion), Bi (Xiaoyujia ore-searching area), B2(Pinglidian ore-searching area), B3 (Liu village gold mining area periphery and depth portion), Ci (Zuo village ore-searching area),C2 (Haojia ditch ore-searching area), C3 (Fan ridge ore-searching area). |
