Problems solved by technology

However, for the first method, there are two problems in the test of inclusions in the late stage of direct bonding of rocks. The first problem is to measure the temperature with a glass piece. This method is likely to cause the homogeneous temperature of the inclusions to be higher than the actual homogeneous temperature. And the higher the actual homogenization temperature of the inclusions, the higher the test results; the second problem is to dissolve the inclusions. The homogenization temperature tested by this method is relatively accurate, but the inclusions are easy to break, which is not conducive to the same The group carried out multiple test analysis
The method of boiling gelatin can solve the problems brought by the first method, but the long-term high-temperature boiling gelatin will cause the destruction of the inclusions in the rock slices; High experimental error is difficult to estimate

Embodiment 1

[0027] A flat surface is cut out of the rock sample and the flat surface is polished. Put the polished rock in a Teflon cup, add Petroepoxy154, its depth is not over the rock sample. The Teflon cup was placed in a high pressure casting instrument, the pressure was set at 1.3 MPa, and the temperature was set at 40°C. After 1 hour, the rock samples were taken out and placed at room temperature (25°C) for 0.5 hours. Afterwards, the polished surface of the rock sample was bonded to a glass slide with fir glue, and then sliced ​​and polished to obtain a fabricated thin slice of fluid inclusions.

Embodiment 2

[0029] A flat surface is cut out of the rock sample and the flat surface is polished. Put the polished rock in a Teflon cup, add Petroepoxy154, its depth is not over the rock sample. The Teflon cup was placed in a high pressure casting instrument, the pressure was set at 1.1 MPa, and the temperature was 50°C. After 1.2 hours, the rock samples were taken out and placed at room temperature (25°C) for 0.5 hours. Afterwards, the polished surface of the rock sample was bonded to a glass slide with epoxy resin, and then sliced ​​and polished to obtain a fabricated thin slice of fluid inclusions.

Embodiment 3

[0031] A flat surface is cut out of the rock sample and the flat surface is polished. Put the polished rock in a Teflon cup, add Petroepoxy154, its depth is not over the rock sample. The Teflon cup was placed in an airtight container, evacuated to a pressure of 0.5 MPa, and heated to 45° C. for 1.5 hours. After 1.2 hours, the rock samples were taken out and placed at room temperature (25°C) for 0.5 hours. Afterwards, the polished surface of the rock sample was bonded to a glass slide with 502 glue, and then sliced ​​and polished to obtain a prepared thin slice of fluid inclusions.

[0032] The entire flake production process of the present invention will not affect the test and analysis results of fluid inclusions in the later stage; the prepared rock flakes can be dissolved from the glass with acetone, etc., and the glue injected into the rock will not be dissolved, thereby ensuring that the rock The sheet will not be broken, which can improve the test and analysis results ...

Abstract

The invention provides a manufacturing method of a fluid inclusion slice. The method comprises the following steps carried out in sequence: (1) cutting out a plane on a rock sample, and polishing the plane; (2) injecting glue into the rock sample obtained in the step (1) by adopting glue; (3) solidifying the glue injected into the rock sample obtained in the step (2); and (4) adhering the polished plane of the rock sample obtained in the step (3) to a glass sheet by adopting an adhesive, and performing slicing and polishing to obtain the fluid inclusion slice, wherein the glue used in the step (2) is indissoluble in acid, alkali and / or an organic solvent, and the adhesive used in the step (4) is easily dissoluble in acid, alkali and / or an organic solvent. By virtue of the manufacturing method provided by the invention, a more perfect fluid inclusion slice can be manufactured; and the manufacturing method serves for obtaining a first-class fluid inclusion slice analysis result, and then serves for geological researches of study of mineral deposits, petroleum geology and the like.

Description

technical field [0001] The invention relates to the field of mineral exploration, and more specifically, to a method for making a fluid inclusion sheet. Background technique [0002] Fluid inclusions in rocks are the only research method that can provide direct information on geological fluid activities in the process of geological evolution history. Therefore, the research results of fluid inclusions can be widely used in fields such as mineral deposits, petroleum geology, structural geology, fluid migration in the earth's interior, and the evolution process of magmatic rock systems. [0003] Traditionally, there are two methods for making fluid inclusion sheets: direct grinding and gel boiling. The direct grinding method first cuts out a plane from the rock and polishes it; then sticks it on the glass slide with epoxy resin or fir glue; then cuts and polishes the other side to a thickness of 20-60 μm. The basic steps of the glue boiling method are basically the same as t...
