Description
Technical Field
The invention relates to the technical field of target preparation, in particular to a sample target composed of diamond and an internal mineral inclusion and a preparation method thereof.
Background
Because of the limitation of technological means, samples (such as diamond and the like) from the deep part of the earth are extremely rare, and people know the deep mantle mainly through indirect means such as high-temperature and high-pressure experiments, seismology and astrochemistry research and the like, so that the understanding of the composition and evolution of the deep substances of the earth is restricted to a certain extent. The early stage mainly adopts a crushing method to take out mineral inclusion in the diamond, and tests the C isotope of the diamond by a combustion method, so that the integrity of a sample is destroyed, and the rare sample cannot be maximally utilized for multi-element test analysis.
In recent years, the modern in-situ micro-region microbeam technologies such as LA-ICPMS, SHRIMP and SIMS are applied to single mineral isotope composition research, so that samples are well reserved and the data accuracy of the samples is greatly improved. For common silicate minerals and oxides, epoxy targets are often made when testing for O isotopes. For rare diamond samples with extremely high hardness, the samples often contain mineral inclusion such as silicate, oxide or sulfide, if epoxy targets or alloy targets which are suitable for testing the equivalent element composition of the mineral inclusion O, S and indium targets which are suitable for testing the isotope composition of the diamond C, N are respectively manufactured, the steps are complicated, and a plurality of target manufacturing procedures can lead to abrasion and even deletion of the mineral inclusion, so that the mineral inclusion polished out of the surface is more rare. Thus, it is highly desirable to prepare sample targets suitable for in situ simultaneous analysis of diamond and its internal mineral inclusion C, N, O, S multi-isotope composition.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a sample target composed of diamond and a mineral inclusion therein and a preparation method thereof, wherein the sample target can simultaneously test the isotope composition of the mineral inclusion O, S and the isotope composition of the diamond C, N, and has simple flow and convenient operation.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
In a first aspect, the present invention provides a method of preparing a sample target of diamond and its inner mineral inclusions comprising the steps of:
(1) Cutting and polishing the diamond containing the mineral inclusion to obtain a sheet sample with the thickness of 0.8-1.2 mm;
(2) Placing solid indium into an alloy target holder, heating to 160-200 ℃, and cooling to obtain an indium target;
(3) And (3) placing the sheet sample on an indium target, compacting, and keeping the target surface flat to obtain the sample palladium consisting of the diamond and the mineral inclusion in the diamond.
The sample target composed of the diamond and the mineral inclusion in the diamond can respectively carry out O-S, C-N multi-element isotope test on the mineral inclusion and the host diamond on the same plane, has a flat target surface and meets the sample requirement of an ion probe on isotope system test. The principle is as follows: the liquid indium has low melting point and is stable in air, the C, N, O, S isotope system is not interfered, meanwhile, the liquid indium has better ductility, the diamond thin sheet can be placed in the liquid indium in sequence, and redundant indium blocks are cut after flattening. In addition, the diamond sheet containing the mineral inclusion is fixed on the indium target for testing by adopting the method, so that the prepared diamond containing the mineral inclusion can maintain long-term stability and detection accuracy, the rare mineral inclusion is well protected, the possibility that the rare mineral inclusion is worn or even lost in the process of target making is reduced, the target making period is effectively shortened, and the target making efficiency is greatly improved.

In the invention, the thickness of the diamond is enough to contain mineral inclusion, so that the thickness is kept uniform as much as possible, and the target is conveniently manufactured. If the thickness of the diamond is too large, the diamond sample is wasted; if the thickness of diamond is too small, the mineral inclusion cannot be well protected. Therefore, the thickness of the diamond sheet sample is controlled in the range, the O-S, C-N multi-isotope test is conveniently carried out on the mineral inclusion and the diamond respectively, and the integrity of the mineral inclusion can be protected, so that the situation that the mineral inclusion is worn or lost in the target making process is reduced.
Preferably, the diameter of the alloy target holder in the step (2) is 8-12mm.
In the invention, if the diameter of the alloy target holder is too large or too small, the on-machine test is inconvenient; and the diameter of the alloy target holder is too small, so that the diamond can not be well fixed, and the multi-isotope test of the mineral inclusion and the diamond is influenced. Therefore, the alloy target holder is controlled in the range, so that the operation is convenient, and the O-S, C-N multi-isotope test can be better performed on the mineral inclusion and the diamond respectively.
Preferably, in step (2), the solid indium is heated to 180 ℃.
Preferably, in the step (3), the liquid indium in the alloy target holder is cooled to 30-50 ℃, and then the redundant solid indium is cut off, so that the redundant solid indium can be better cut off, and the solid indium solidified in the alloy target holder is not influenced, thereby better improving the target making efficiency.
Preferably, the diameter of the mineral-containing inclusions in the diamond in step (1) is 10-500um.
More preferably, the diameter of the mineral-containing inclusions in the diamond in step (1) is 30-120um.
In the invention, the diameter of the mineral inclusion in the diamond is in the range, which is favorable for carrying out O-S, C-N multi-isotope test on the mineral inclusion and the diamond respectively.
Preferably, the pretreatment of the sheet sample in the step (1) includes the following steps: firstly, cleaning a slice sample by using ultrasonic waves, then wiping the surface of the slice sample clean, repeating for 3-4 times until oil stains and impurities on the surface cannot be seen under a microscope, and then placing the cleaned diamond into a sample bag for standby.
According to the method, the diamond is pretreated by the method, so that oil stains and impurities on the surface of the diamond are removed completely, and the mineral inclusion and the diamond are not easily affected by the oil stains and the impurities when being subjected to the O-S, C-N multi-isotope test, thereby being beneficial to improving the accuracy of the test.
In a second aspect, the invention also provides a sample target composed of the diamond prepared by the method and the mineral inclusion therein.
Compared with the prior art, the invention has the beneficial effects that:
(1) The sample target composed of the diamond and the mineral inclusion in the diamond can respectively carry out O-S, C-N multi-element isotope test on the mineral inclusion and the host diamond on the same plane, has a flat target surface and meets the sample requirement of an ion probe on isotope system test.
(2) According to the invention, the diamond sheet containing the mineral inclusion is fixed on an indium target for testing, so that the prepared diamond containing the mineral inclusion can maintain long-term stability and detection accuracy, the rare mineral inclusion is well protected, the possibility that the rare mineral inclusion is worn or even lost in the target preparation process is reduced, the target preparation period is effectively shortened, and the target preparation efficiency is greatly improved.
