Rapid preparation method for lumen grinding disc of deep-sea foraminifera

Abstract

The invention relates to the disciplines of marine biology, paleoceanography and sedimentary geology, can be applied to the field of the identification research of the species of foraminifera, the research of marine environment indication, the research of paleoenvironmental reconstruction and global change, and the like, and in particular provides a rapid preparation method for a lumen structure grinding disc of deep-sea foraminifera. The foraminifera obtained from the separation of deep-sea sediments are subjected to gum dipping lumen, hanging drop embedding, positioning fixation and water-grinding disc processing, that is, a complete grinding disc of the lumen structure of the deep-sea foraminifera is quickly obtained. The method provided by the invention, through the layer information obtained by the grinding disc, can more accurately identify the species of foraminifera, avoids scientific confusion such as identification errors caused by external morphological variations such as the shape, texture and number of compartments of the worm body, and provides accurate scientific basis and quick problem solving solutions for the disciplines of accurate identification of the species of deep-sea foraminifera, the research thereof of marine environment indication, the research of paleoenvironmental reconstruction, the research of global change, and the like.

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
