Rapid Preparation Method of Internal Cavity Polishing of Deep-sea Foraminifera

Abstract

The present invention relates to marine biology, paleoceanography, sedimentary geology and other disciplines, and can be applied in the fields of foraminifer species identification research, marine environment indication research, paleoenvironment reconstruction and global change research, etc. Specifically, it is a A rapid preparation method for deep-sea foraminifera lumen structure grinding plate. Foraminifera isolated from deep-sea sediments were treated with gum immersion, hanging drop embedding, position adjustment and water grinding, that is, complete grinding of the inner cavity structure of deep-sea foraminifera was quickly obtained. The invention can more accurately identify the species of the foraminifera through the level information obtained by grinding, and avoid scientific confusion such as identification errors caused by external morphological variations such as the shape, texture, and number of chambers of the foraminifera. The invention provides accurate scientific basis and quick problem-solving scheme for the accurate identification of types of deep-sea foraminifera and the research on indications to the marine environment, paleoenvironment reconstruction research, global change research and other subject fields.

Description

technical field [0001] The present invention relates to marine biology, paleoceanography, sedimentary geology and other disciplines, and can be applied in the fields of foraminifer species identification research, marine environment indication research, paleoenvironment reconstruction and global change research, etc. Specifically, it is a A rapid preparation method for deep-sea foraminifera lumen structure grinding plate. Background technique [0002] The method for preparing traditional grinding discs has no research plan suitable for deep-sea foraminifera with thin and brittle shells. In addition, the operation steps, chemical materials and experimental tools required for experiments are completely different from those of the present invention, and there are experimental operations. The content is cumbersome, the experiment process takes a long time (1-3 months), and the success rate is low, and it is easy to cause the specimen to rupture and the experiment to fail. The s...

Problems solved by technology

[0003] (1) It is necessary to make films and prepare glue in advance, and use liquid glue materials to bake glue, which is time-consuming and labor-intensive, and it is easy to cause partial aging of the gum. The baking process is difficult to control, and the curing degree of the glue needs to be checked from time to time

[0004] (2) In the process of burying fossils, foraminifera specimens are likely to be hollow inside, which will cause the specimens to break during the grinding and flipping process; in addition, due to the high viscosity of the glue solution when the traditional method is baked, the air bubbles inside the specimen It is difficult to drain all at once. It needs to be repeated many times and the air bubbles are manually broken with a dissecting needle. After the glue is completely solidified, it is heated again. Affects the observation of fossils and identification results; if the baking glue is too old, it will cause a lot of air bubbles, which will cause the specimen to break during the grinding process, and the experiment will fail

[0005] (3) During the grinding and sealing process, due to the traditional method of baking the glue first and then burying the fossils, the colloid becomes hard and brittle after solidification, and its elasticity becomes smaller. Structural fractures occur from time to time, resulting in incomplete specimens and even experimental failures
