Problems solved by technology
[0004] The technical problem to be solved by the present invention is to provide a non-destructive analysis method for quickly determining the type of lunar glass, which is a non-destructive, fast and low-cost method for discriminating the type of lunar glass used in the laboratory. The method adopts Raman spectroscopy It can better distinguish the lunar glass without causing damage and pollution to the sample. It is not only the technical basis for the analysis and research of my country's Chang'e-5 return to the lunar soil sample laboratory, but also can provide a basis for future lunar sample Raman data interpretation and lunar exploration. The load design provides support, which effectively solves the above-mentioned problems such as sample destruction, pollution, high cost, large sample volume, and low spatial resolution.

Embodiment 1
[0021] Embodiment 1: as attached Figure 1~6 As shown, a non-destructive analysis method for quickly determining the type of lunar glass, the method includes the following steps: 1. Using a micro-Raman spectrometer to collect the Raman spectrum of the lunar glass; 2. Analyzing the Raman spectrum at 400-600cm -1 Raman peak position in the Raman shift range (RPP 400–600 ) to identify the type of lunar glass.
[0022] The discriminant method of step 2 is: RPP 400–600 >570cm -1 The Lunar Glass is Lunar Volcanic Glass, RPP 400–600 -1 The moon glass is the moon impact glass.
[0023] In step 2, when the RPP 400–600 -1 , then according to the Raman spectrum at 400–600cm -1 with 800–1200cm -1 Raman peak position within the Raman shift range (RPP 400–600 and RPP 800–1200 ) can be used to discriminate the type of moon impact glass.
[0024] The method for judging the type of glass impacted by the moon is as follows: when the RPP 800–1200 >1510-RPP 400–600 That is, the mare h...

The invention discloses a non-destructive analysis method for quickly determining the type of lunar glass. The method includes the following steps: 1. collecting the Raman spectrum of the lunar glass by using a micro-Raman spectrometer; 2. analyzing the Raman spectrum at 400-600 cm ‑1 Raman peak position in the Raman shift range (RPP 400–600 ) to identify the type of lunar glass. It is a non-destructive, fast and low-cost method for identifying the type of lunar glass used in the laboratory. This method can better distinguish lunar glass by using Raman spectroscopy without causing damage or pollution to the sample. Not only in our country The technical basis for the analysis and research of Chang'e-5's return to the lunar soil sample laboratory can also provide support for future lunar sample Raman data interpretation and lunar exploration load design, which can realize non-destructive, non-polluting, high-efficiency and low-cost of different types of lunar glass Accurate identification.
Description
technical field [0001] The invention relates to a lunar glass analysis method, in particular to a non-destructive analysis method for quickly determining the type of lunar glass, and belongs to the technical field of lunar glass analysis. Background technique [0002] The fine-grained regolith (lunar soil) widely distributed on the surface of the moon is an important carrier for studying the formation and evolution of the moon, geological processes, and the space environment of the lunar surface. Lunar soil is usually composed of various rock fragments, mineral debris, and a certain amount (volume ratio ~20%-30%) of glassy substances, etc. These vitreous substances generally include: glasses of volcanic origin and glasses of impact origin. The former was formed by lunar volcanic eruptions, and is an important research object for understanding the composition of the moon’s interior materials and the evolution of the moon’s mantle; while the impact glass is the material forme...
