Method for accurately measuring homogeneous temperature of volatile component-rich melt inclusion

Abstract

The invention relates to the technical field of uniform temperature measurement of melt inclusions, and particularly discloses a method for accurately measuring the uniform temperature of a volatile-component-rich melt inclusion, which comprises the following steps: step 1) preparation of an inclusion sample: preparing a quartz slice containing a target melt inclusion; (2) preparing a sample chamber: fixing a rhenium sheet on a diamond anvil surface at the lower half part of the hydrothermal diamond anvil cell; (3) loading an experimental sample: putting the quartz sheet containing the target melt inclusion into a central hole of the rhenium sheet; 4) preheating, and adjusting the volume of bubbles in the sample chamber; (5) heating, homogenizing and measuring temperature: heating the sample chamber by using a temperature controller until the temperature is completely homogenized into a melt phase, and measuring the completely homogenized temperature; the hydrothermal diamond anvil cell is applied to the uniform temperature measurement experiment of the volatile component-rich melt inclusion, so that the burst or leakage of the volatile component-rich melt inclusion can be prevented, the in-situ real-time observation can be realized, and the measured uniform temperature value is more accurate.

Description

technical field [0001] The invention relates to the technical field of uniform temperature measurement of melt inclusions, in particular to a method for accurately measuring the uniform temperature of volatile-rich melt inclusions. Background technique [0002] Melt inclusions are natural magma samples captured during the crystallization growth of igneous rock minerals. After being captured under high-temperature and high-pressure environments, melt inclusions have been sealed in relatively incompressible host minerals, so they can effectively preserve a large amount of physical and chemical information about the surrounding magmatic medium when their host minerals were formed. It is a very important aspect in the study of ore deposits to carry out uniform temperature measurement on melt inclusions, and to be able to invert the temperature conditions (diagenetic and mineralization temperature) at the time of their formation. [0003] At present, the equipment used for the h...
