Embodiment Construction

[0041] Multi-element optimal set control exploration of Longshan gold-antimony deposit.

[0042] The Longshan gold-antimony deposit is located in Taizhimiao Township, Xinshao County, Hunan Province. The deposit is produced in the shallow metamorphic strata of the Sinian Jiangkou Formation. It is controlled by sandy argillaceous clastic rock formations, fault fracture zones and deep magmatic hydrothermal fluids. Mesophilic magmatic hydrothermal deposits.

[0043] 28 near-mine altered rock samples were collected in the mid-sections of No. 1 and No. 2 veins of the Longshan gold-antimony mine at elevations of 800 meters, 710 meters and 630 meters. Coefficient, according to the target grouping method to make the target grouping dendrogram as figure 1 , to calculate the eigenvalue of its correlation coefficient, the preferred ore-controlling elements closely related to gold are: Sb, As, MgO, Se, Al 2 o 3 , Th, Zr, Bi, Fe 2 o 3 , MnO 2 , Y, Be, V, In 14 elements. Calculated by...

Abstract

The present invention relates to ore deposit prospecting method and is especially one multielement optimized control method of prospecting ore deposit. The optimized method finds out the abnormal theoretical value characteristic of the ore-forming elements and spatial distribution rules based on the analysis and test of all elements in samples from the prospected area to reach the aim of prospecting ore deposit. The specific steps includes field operation and laboratory analysis and test, including clustering analysis, target grouping analysis, dendrogram drawing, ore-controlling element optimization, regression equation establishment for ore-forming elements and ore-controlling element, ore-forming element theoretical value calculation, drawing, etc.

Description

technical field [0001] The invention relates to an ore prospecting method; in particular, it relates to a multi-element optimization set control method for ore prospecting. Background technique [0002] The traditional geochemical prospecting methods of ore deposits include primary halo geochemical prospecting, secondary halo geochemical prospecting, hydrogeological chemical prospecting, heavy sand measurement, genetic mineralogy prospecting, etc., all of which can obtain the spatial distribution of single element content in an instant The ore prospecting prediction is carried out according to the law or the distribution law of a single mineral or mineral habit in space. Due to the influence of internal and external geological effects and human activities after the formation of ore deposits, the geochemical halo of ore deposits is often destroyed, or there are superimposed elements, which directly affect the effect of ore prospecting. Sometimes duri...
