Delineation method of pegmatite lithium deposit based on γ total amount and high-density electric method measurement

Abstract

The invention discloses a delineation method of pegmatite lithium ore based on gamma total amount and high-density electric method measurement, which includes collecting the gamma irradiation rate on each section and the apparent resistivity and apparent polarity at different depths of the section. Mark the abnormal measurement points in the apparent resistivity, apparent polarizability and gamma irradiation rate; input the apparent resistivity and apparent polarizability into the inversion software to obtain the apparent resistivity profile and apparent polarizability profile; Use Mapgis software to generate the planar profile of the total gamma measurement; input the format-converted apparent resistivity profile, apparent polarizability profile and planar profile into Mapgis software to generate a comprehensive profile; use abnormal measurement points in the profile profile Circle the first occurrence area and the second occurrence area respectively; mark the overlapping first occurrence area and the second occurrence area as pegmatite dike lithium ore-rich area, and mark the remaining first occurrence area And the second occurrence area is marked as the suspected area of ​​pegmatite dike lithium deposit.

Description

Technical field [0001] The present invention relates to the field of deposit surveying techniques, and more particularly to a circle-specific method based on the total amount of γ and high density electrical method. Background technique [0002] Lithium mine is an important strategic mineral, including the two-semilitational lithium ore, a salt lake-type lithium mine and granite-shaped, granite, and a salt lake-type lithium ore, a salt lake, which is currently accompanied by a brine-type lithium ore. The development and utilization technology has not yet achieved better breakthroughs, and the new energy lithium battery industry uses lithium resources in the same manner as the main material source of hard rock type lithium ore. [0003] The prospecting method of traditional Wenjing rock lithium mine is to determine the target area through regional geological surveys, special geological surveys, and chemical probe and other means, and then expose the verification through a large nu...

AI Technical Summary

Problems solved by technology

[0003] The traditional pegmatite lithium ore prospecting method is to determine the target area through regional geological survey, special geological survey, chemical exploration and other means, and then expose and verify through a large number of trenching work. There are several problems in the process: in Sichuan In many places, the mountains are high and the forests are dense, and the terrain is severely cut. The geological survey work requires a lot of manpower and material resources. A large amount of trenching work cannot be carried out by large-scale machinery. The trenching can only be excavated manually, which is inefficient and takes a long time. Add more costs; in addition, under the current situation, under the stricter requirements of environmental protection, the concept of green exploration is advocated, and the traditional geological prospecting through a large number of trenches to reveal ore will be more and more restricted
