Embodiment Construction

[0026] The scheme of the present invention will be described in detail below in conjunction with an example of ore prospecting in the Dongshan tin-silver-zinc-copper-lead polymetallic deposit in Baiyinchagan, Inner Mongolia.

[0027] The first step is to select the Baiyinchagan Dongshan polymetallic ore-forming area in Inner Mongolia to deploy prospecting work. This area is located in the Huanggangliang-Dajing polymetallic ore-forming area of ​​the Paleozoic-Mesozoic-Cenozoic polymetallic ore-forming belt in the Greater Khingan Mountains of Inner Mongolia, surrounded by the Maodeng tin-copper deposit, the Dajing tin-polymetallic deposit, the Baiyinnur lead-zinc deposit and the Bairen Daba silver deposit. Lead-zinc deposits, etc.; Yanshanian granite porphyry branches are distributed in the southwest of the exploration area; there are extensional faults near EW trending in the middle of the exploration area, and are dislocated by NE trending faults ( figure 1 ). These favorable...

Abstract

The invention discloses a hidden polymetallic ore prospecting method. The method utilizes a rock debris geochemistry, a induced electric medium gradient scanning surface and a controllable source audio magnetotelluric sounding method to explore a hidden polymetallic ore bed controlled by a fracture structure, firstly selects a favorable polymetallic ore mining area according to a geological miningrule, and then utilizes the rock debris geochemistry measurement and defines a multi-element combined abnormal group; then, in the multi-element combined abnormal group area, an occurrence area of the polymetallic ore is defined by utilizing the induced electric medium gradient scanning surface; and finally, in the occurrence area of the polymetallic ore, the high-resistance mineralization and alteration zone is defined by utilizing the controllable source audio magnetotelluric sounding measurement. The hidden polymetallic ore prospecting method has the characteristics of accurate position identification of the blind deposit and obvious prospecting effect. By adopting the method, the prospecting breakthrough of the tin-silver-zinc-copper-lead polymetallic ore hidden under loose sedimentsis realized in the Baiyin Chagan Dongshan mining area of the Inner Mongolia Autonomous Region.

Description

technical field [0001] The invention relates to the technical field of hidden ore prospecting in geological exploration, in particular to a hidden vein polymetallic ore prospecting method controlled by a fault structure. Background technique [0002] Mineral resources are an important material basis for social and economic development. More than 95% of human energy, more than 80% of industrial raw materials and more than 70% of agricultural production raw materials come from mineral resources. The total amount of mineral resources in my country is large, but the per capita is small, the endowment is poor, and the bulk and pillar minerals are insufficient. With the continuous and rapid growth of the demand for mineral resources due to economic and social development, the supply of bulk mineral resources in my country is in short supply, such as the external dependence of copper reaching about 70%, which seriously threatens the security of national resources. However, due to ...
