Prospecting method for melting cobalt ore from mountain-making magma

Abstract

The invention relates to a prospecting method for melting cobalt ore from mountain-making magma, which comprises the following steps: selecting a prospecting area in an extension environment in whichlate Silurian epoch-Lower Devonian is in a land-land collision stage, carrying out water system sediment measurement, and preliminarily screening a target area through area aeromagnetic anomaly; carrying out large-scale high-precision gravity and magnetic method measurement on the preliminarily screened target area, and specifically delineating a basic-super basic rock mass; preliminarily screening an ore-bearing rock mass through a controllable source audio magnetotelluric method according to the delineated basic-super basic rock mass, carrying out large-scale soil geochemical measurement, and determining a cobalt ore prospecting clue; and delineating ore bodies through further sampling analysis of surface mineral geological survey, groove exploration and drilling. The prospecting methodcan reduce the prospecting range, has the advantages of being short in prospecting period, capable of improving the prospecting success rate and high in prospecting efficiency, and meanwhile can be widely applied to finding of various metal ores in a magnesium-iron-ultra-magnesium-iron rock area.

Description

Technical field [0001] The invention relates to the field of prospecting methods, in particular to a prospecting method for orogenic magma fused cobalt ore. Background technique [0002] Orogenic deposits are formed in a tectonic environment where the edges of the convergent plates are squeezed or twisted. They are controlled by structures and are genetically related to orogenic processes in time and space. Magma dissociated ore deposit refers to a homogeneous magma melt at a higher temperature, when the temperature and pressure drop, it separates into two or more immiscible melts and forms a deposit. [0003] The ore-bearing lithology, ore-controlling elements, and ore body characteristics of the basic-ultrabasic rock cobalt deposit produced in the extensional environment of the continental-continent collision stage are different from those of other regions. Conventional electrical methods such as transient electromagnetic sounding methods are difficult to complete the correspond...

AI Technical Summary

Problems solved by technology

[0003] The ore-bearing lithology, ore-controlling elements and ore body characteristics of the basic-ultrabasic cobalt deposits produced in the extensional environment of the continental-continental collision stage are different from those in other areas. According to the conventional DC resistivity sounding and Conventional electrical methods such as transient electromagnetic sounding methods are difficult to complete the corresponding exploration work; and may prolong the exploration cycle, low ore prospecting efficiency and inconspicuous ore prospecting effect, etc.
