Abstract

The invention provides a method for discriminating the redox property of an ore-forming fluid based on the cathodoluminescence characteristic of scheelite in a quartz vein type deposit. The method comprises the following steps: obtaining multiple scheelite samples; choosing scheelite particles based on the mineralogy, the morphology and the output characteristics of the scheelite particles in thescheelite samples in order to obtain high-quality scheelite particles; obtaining the scanning electron microscopy-cathodoluminescence images and the back scattering images of the high-quality scheelite particles; dividing the high-quality scheelite particles based on the scanning electron microscopy-cathodoluminescence images and the back scattering images according to the morphology and internalstructural characteristics of the scheelite particles in order to obtain multiple types of the high-quality scheelite particles; carrying out in-situ analysis on rare earth elements in the multiple types of the high-quality scheelite particles to obtain europium content and molybdenum content data; and establishing an element distribution map according to the europium content and molybdenum content data, wherein the element distribution map is used for indicating the redox property of the ore-forming fluid for forming the scheelite.

Description

technical field

[0001] The invention relates to the field of research on characteristics of scheelite ore-forming fluids in quartz vein-type deposits, in particular to a method for distinguishing redox properties of ore-forming fluids based on cathode luminescence characteristics of scheelite in quartz vein-type deposits. Background technique

[0002] Quartz vein type tungsten deposit is the type of tungsten deposit with the longest mining history, the most abundant output, the widest distribution and the deepest research degree in my country. The main body of the quartz vein type tungsten deposit is quartz vein, and there are also quartzite type, granite type, etc. Mineralization, as well as veins or alterations such as greisen veins, carbonate veins, and arsenopyrite topaz layers, these mineralization, alterations, and the time-space relationship of related rock masses and strata, etc., together constitute the quartz vein type tungsten The metallogenic subsystem of the depos...
