Abstract

The invention relates to the technical field of deep prospecting of geological exploration, and provides a skarn type iron-rich ore deep exploration method and system based on multi-element geophysics, the method combines direct prospecting with indirect prospecting, adopts multiple geophysical methods such as gravity, magnetic method, electrical method, earthquake and the like, exerts the advantages of each geophysical method, and improves the exploration efficiency. According to the method, cross constraint and joint interpretation of multi-element geophysical information are carried out, deep ore body extension is deduced, drilling verification is carried out, geophysical well logging is carried out, geophysical interpretation results are repeatedly corrected with drilling and well logging information as constraints, accurate positioning of the hidden magnetite body is achieved, the exploration success rate is increased, and the exploration cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of deep ore prospecting in geological exploration, and in particular relates to a deep exploration method and system for skarn-type iron-rich ore deposits based on multivariate geophysics. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the increase of the exploration depth, the difficulty of obtaining deep geological information has increased significantly, and the drilling cost has also increased significantly. The traditional prospecting method of "drilling as the mainstay and geophysical exploration as a supplement" has gradually been transformed into "both geophysical exploration and drilling" in order to improve drilling insights. Ore rate and reduce exploration cost. Skarn-type iron-rich ore is easily affected by multiple factors such as overlying stratum shie...
