Abstract

The invention belongs to the technical field of isotope composition determination of rocks and minerals, and particularly relates to an analyzing and extracting device and method of oxygen isotope composition in the rocks and the minerals. The analyzing and extracting device comprises a waste treatment system, a first 1 / 2 inch stainless steel vertical main pipeline and twelve sets of identical oxygen isotope sample extraction, separation, purification and collection systems; the analyzing and extracting method comprises the following steps that 1, sample introducing is conducted; 2, a whole system is baked to be vacuum-degassed; 3, pentafluoride bromine reagent is transferred, and fluorination reaction is conducted; 4, oxygen is separated, purified and collected; and 5, the waste is treated. According to the analyzing and extracting device and method of oxygen isotope composition in the rocks and the minerals, the problem that oxygen isotope fractionation is prone to being caused in the process of isotope sample preparation can be solved, and the accuracy of analysis and test and the efficiency of analysis and test are improved.

Description

technical field [0001] The invention belongs to the technical field of determination of isotope composition of rocks and minerals, and in particular relates to an analysis and extraction device and method for the composition of oxygen isotopes in rocks and minerals. Background technique [0002] The determination of oxygen isotope composition in rocks and minerals can be used to study the formation conditions and mechanism, source, evolution and interaction with surrounding rocks of minerals and rocks. Oxygen isotope analysis has become a powerful tool for petrology and mineralogy research. It plays a very important role in revealing the source, migration, evolution and ore-forming process of ore-forming fluids, and provides a theory for clarifying the ore-forming mechanism of ore deposits. in accordance with. Fully extracting, purifying and completely collecting oxygen in rocks and minerals is the prerequisite for analyzing the oxygen isotope composition in rocks and miner...
