Deep prospecting method based on primary halo of typical tungsten deposit

Abstract

A deep prospecting method based on the primary halo of a typical tungsten deposit includes the following steps: (1) establishing the ore-forming and halo-forming characteristic and an indicator for deposit of a typical tungsten deposit by the axial zoning sequence of abnormal elements and the correlation between W and various abnormal elements; (2) screening out an ore area containing the typicaltungsten deposit in a magmatic hydrothermal type-quartz vein type ore-forming system; (3) by steps of determining the lower limit of primary halo anomaly, homogenizing drilling data, and determining the single-element primary halo anomaly, creating a multi-element primary superimposed halo map of the deep prospective prospecting line profile in the ore area; (4) determining a deep prospecting target area by analogy with the ore-forming halo-forming characteristic and the indicator for deposit of the typical tungsten deposit; (5) and performing drilling verification. The method can convenientlyand quickly acquire the information of deep ore deposits, obtains a high prospecting success rate with a low exploration cost, and can accurately determine the prospecting target area according to the combination of abnormal elements and horizontal zoning features.

Description

technical field [0001] The invention relates to a deep ore prospecting method for solid minerals, in particular to a deep ore prospecting method based on the primary halo of a typical tungsten ore deposit. Background technique [0002] Tungsten ore (chemical) bodies mainly occur in sand slate, mainly in quartz vein type. A large number of fault structures are developed in the mining area, which are channels for mineral migration and storage space for hydrothermal precipitation. Ore formation is the magma-hydrothermal fluid rich in volatile matter and ore-forming elements in the deep heat source body (granite) that provides heat and ore sources for mineralization; The rock marble plays a certain shielding effect, so that the ore-forming materials and ore-forming fluids can be well preserved. [0003] In the magmatic hydrothermal type-quartz vein type tungsten mineralization system, the mineralization is often slightly different, and the vertical zoning sequence of the primar...

Problems solved by technology

As for whether there is reappearance in the deep part of the detected ore body, due to the limited understanding of the deep part of the geological survey and the multiple solutions of the geophysical prospecting method, the deep prospecting prediction basis provided by the geology and geophysical prospecting is limited, and the effect is poor
