Soil Geochemical Exploration And Prospecting Forecast In Lianghekou Exploration Area Of Western Henan Xiong’ershan

by having exploration on the Lianghekou geological exploration area and collation on the material we collected,according to the basic geological summary of exploration area and research on three geological section soil profiles,calculate and analyse the 1: 5000 soil geochemical data so as to obtain the enrichment factor and anomaly threshold of each element of the exploration area,then made single-element geochemical maps,geochemical anomaly maps to determine the abnormalities of elemental composition of exploration area, make the element combination anomaly maps, prospecting prediction map,do demonstrated potential analysis to each element of exploration zone, propose the prospecting targets according to the forecasts.the following is the main understanding:(1)The geology exploration area is relatively simple. exploration area is mainly composed of medium-and coarse-grained monzogranite. the northeast are the fine grained syenogranites formed by late yanshanian magma intrusion activities and its long dikes. north and south. has of late yanshanian magmatic intrusive granite porphyry dikes. the late yanshanian magmatic activity is likely to be a major cause of mineralization.(2)compared to china’s average content of soil elements.the content of w.sn.mo.pb.zn five elements of lianghekou prospecting area occurs enrichment. and the enrichment coefficients were 2.03,2.62,3.09,2.30,1.57. while the content of another three elements such as Au.Ag.As has not reached china’s average content of soil elements.(3)on the basis of both correlation analysis and clustering analysis to the 9 elements named W.Mo.Sn.Cu.Pb.Zn.Au.Ag.As.we confirmed the element combination of district ore prospecting as ○1 W-Sn-Mo mainly formed by the late yanshanian magma intruding into the medium-and coarse-grained monzogranite once again at high temperature.and the ○2 Pb-Zn-Ag was mainly formed in the case of the second and third the similar intrusion at medium temperature.(4)According to the element combination.size. intensity and area of metallogenic.exploration area can be divided into two sections:Y1 and Y2. Y1 is located in the middle of exploration area as well as the northeast of zhaogou.of which the main elements of or e prospecting are pb.zn.w.mo.sn;Y2 is located in the south of exploration area as well asshalishu. of which the main elements of ore prospecting are Pb.Zn.Ag.In summary,we can get from the above is that exploration area has the ability of metallogening. The next step should continue to increase research on the exploration area.
