摘要
Abstract
In response to the exploration difficulties of hidden fluorite deposit in shallow coverage areas,a"geological-physical-chemical"collaborative exploration system has been constructed innovatively,and high precision magnetic surveying,induced polarization,and soil geochemical exploration technologies have been integrated to reveal geophysical-geochemical response characteristics of hidden ore bodies.Through high precision magnetic survey,negative magnetic anomaly areas have been circled,and polariza-tion bands have been identified through induced polarization gradient.Combining with fluoride calcium a-nomaly tracking,5 target areas have been accurately delineated in Quaternary coverage area of Fangcheng county.It is revealled that the buried depth of the ore body is 36.5~52.3m,and the thickness is 2.6~5.2m.It is confirmed that there is a spatial coupling law between physical and chemical exploration anoma-lies and the concealed ore body.Geophysical and geochemical characteristics of fluorite deposits in tectonic altered rock types have been revealled.It is proposed that comprehensive geophysical methods and comple-mentary geochemical techniques can effectively suppress ambiguity.This achievement will provide a tech-nical solution for the exploration of concealed fluorite deposits in shallow coverage areas,and has impor-tant demonstration significance for the exploration of similar deposits.关键词
