Embodiment Construction

[0019] The present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention is not limited to the following description.

[0020] The sedimentary rock containing ore lead-zinc ore prospecting method of the present invention is characterized in that comprising the following steps:

[0021] a. According to the regional geological environment, the temporal and spatial distribution of lead-zinc deposits and the genetic type of deposits, the explored area is determined to be a sedimentary rock-hosting Pb-Zn-Cu polymetallic ore-forming subsystem related to Cenozoic thrust-nappe structures; The above-mentioned geological environment is a geographical structure formed by geological evolution. For example, the northern section of the Sanjiang River in Qinghai experienced the Paleo-Tethys evolution in the Late Paleozoic-Early Mesozoic, and the Indo-Asia continental collision orogenic evolution stage since the Cenoz...

Abstract

The invention discloses a method for exploring lead zinc ore in a sedimentary rock host. The method has the advantages that exploration efficiency is high, and the exploration period is short. The method comprises the following steps that firstly, according to the geographical environment and spatial-temporal characteristics, whether a metallogenic system is a sedimentary rock host Pb-Zn-Cu multi-metal metallogenic subsystem is analyzed and judged; secondly, according to the characteristics of the sedimentary rock host Pb-Zn-Cu multi-metal metallogenic subsystem, distribution of points, collection of relevant samples and analytical research are conducted; thirdly, the clue of the lead zinc ore is determined according to a sample collection result and an analysis result in the second step; fourthly, a mineral geological survey is conducted; lastly, a trial trench is constructed and a well is drilled for further sampling analysis, and a mineralized zone or an ore body is delineated. The method for exploring the lead zinc ore in the sedimentary rock host has the advantages that the exploration efficiency is high, and the exploration period is short through implementation of the steps.

Description

technical field [0001] The invention relates to an ore prospecting method, in particular to a lead-zinc ore prospecting method mainly used in permafrost regions. Background technique [0002] The ore-bearing structure, ore-controlling elements, and ore body exposure characteristics of sedimentary rock-hosting lead-zinc deposits in permafrost regions are different from those in general areas. Otherwise, the prospecting period may be prolonged, the prospecting efficiency is low, and the prospecting effect is not obvious. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for prospecting lead-zinc ore with high prospecting efficiency and short prospecting period. [0004] The technical solution adopted by the present invention to solve its technical problems is: sedimentary rock host ore lead-zinc ore prospecting method, it is characterized in that comprising the following steps: [0005] a. According to the...
