Large-breadth rock core slice preparation and manufacturing method thereof

Abstract

The invention provides a Large-breadth rock core slice preparation and a manufacturing method thereof. The manufacturing method comprises the following steps: sectioning a columnar rock core sample along a length direction to obtain the rock core sample with a first cutting surface; fixing the rock core sample on a hard base, mounting the hard base on a cutting machine, performing cutting processing on the rock core sample to obtain a rock core slice with a second cutting surface, and enabling the second cutting surface to be parallel to the first cutting surface; separating the rock core slice from the hard base; and adhering the rock core slice to a transparent matrix to obtain a large-breadth rock core slice preparation. By performing sectioning and cutting processing by using differentways, the size of the obtained rock core slice preparation can be much greater than the size of the existing rock core slice preparation, and the direct observation, the display and the long-term storage are convenient. And meanwhile, the cutting surface damage of the rock core sample in the cutting process is effectively reduced, and the waste of the important rock core and the key position andlike geological document is avoided.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a method for making a large-format rock core slice sample and the large-scale rock core slice sample prepared by the method. Background technique [0002] At present, according to the Geological and Mineral Industry Standards of the People's Republic of China - Rock and Mineral Appraisal Technical Specifications, the size of the core cutting edge specimen is only 22mm*22mm, which is relatively small and has a limited application range. Although it is beneficial to scientific research, it is not conducive to direct Observe and show. In addition, the inventors found that small-sized core slice specimens are easy to be lost and hard to find in the process of preservation, and it is difficult to achieve strict protection of important cores and key layers, resulting in the inability to provide technical support for the preservation and utilization of core collections s...
