Device and method for extracting rare gas from rock mineral sample inclusion

Abstract

The invention relates to a device and method for extracting rare gas from a rock mineral sample inclusion, the extraction device comprises a bearing block, a crucible, an extrusion mechanism and a hydraulic driving mechanism, wherein the top surface of the bearing block is provided with a sample pool, and the sample pool is connected with a vacuumizing device and a gas purification device through a ventilation pipeline. The crucible is arranged in the sample pool so as to accommodate a rock mineral sample; an extrusion block is movably arranged in the crucible so as to extrude a rock mineral sample; the extrusion mechanism is hermetically connected to a pool opening of the sample pool and can be propped against the extrusion block; the hydraulic driving mechanism is connected with the extrusion mechanism so as to apply hydraulic driving force to the extrusion mechanism, so that the extrusion block extrudes and crushes the rock mineral sample, and the rare gas in the inclusion is released. The rare gas in the rock mineral sample inclusion is released in a hydraulic extrusion crushing manner, and the extracted rare gas is completely from the inclusion, so that a test result can correctly reflect geological information such as rare gas tracing indication and a metallogenic fluid source.

Description

technical field [0001] The invention belongs to the technical field of geological and mineral exploration, and in particular relates to a device and method for extracting rare gas from rock mineral sample inclusions. Background technique [0002] Noble gases refer to the gases corresponding to all group 0 elements on the periodic table of elements, also known as noble gases, and become important tracers for geological processes because of their unique chemical inertness. In geological and mineral exploration, the rare gas components and isotopes in rock mineral inclusions contain rich ore-forming geological information, which play an important role in tracing and indicating the study of the origin and source of minerals and the period of mineral accumulation. Therefore, the preparation of noble gases in rock inclusions is the premise and guarantee for the analysis of noble gas components and isotopes. [0003] In the prior art, the method of ball milling and crushing is use...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a device and method for extracting rare gases from inclusions of rock mineral samples, so as to solve the problem that in the prior art, ball milling and crushing methods cannot be used to extract pure rare gases from inclusions, and the extracted rare gases contain both inclusions The rare gas released by the body also contains the rare gas released by the lattice, which leads to the technical problems that the subsequent test results of the rare gas cannot correctly reflect the trace indication of the rare gas, the source of the ore-forming fluid and other geological information.
