Microfossil nondestructive separation method
The invention relates to a microfossil nondestructive separation method. The method comprises the following steps: a fragmented rock sample is placed in a dilute acid solution with solute mass concentration being 5-15% for being immersed until the rock is loosen, the immersed sample uses a sieve set...

| description | The invention relates to a microfossil nondestructive separation method. The method comprises the following steps: a fragmented rock sample is placed in a dilute acid solution with solute mass concentration being 5-15% for being immersed until the rock is loosen, the immersed sample uses a sieve set composed of an upper sieve and a lower sieve for sample washing, the sample on the upper sieve andthe sample on the lower sieve are dried after sample washing, and an upper sieve block and a lower sieve sample are respectively obtained; the upper sieve block is broken, and then is subjected to sample washing and sample drying to obtain an upper sieve sample; and sample selection is carried out on a lower sieve sample and the upper sieve sample. During processes of a traditional acidolysis method, the rock sample is immersed in the acid solution during a whole process with long time, and acid etching on the microfossil is severe so that yield and completeness are influenced. According to the provided microfossil no |
