Embodiment
[0027] The non-destructive separation method of microfossils in this embodiment, the flow chart is as follows figure 1 As shown, the following steps are taken:
[0028] 1) Use a crushing machine or hand hammer to crush the rock sample into 3cm 3 The small pieces are uniformly numbered and placed in the sample cylinder;
[0029] 2) At room temperature, add glacial acetic acid solution with a mass concentration of 15% to the sample tank, the glacial acetic acid solution completely covers the sample, and the sample is completely loose after soaking for 24 hours;
[0030] 3) The soaked sample is washed with a set of sieves consisting of an upper sieve and a lower sieve (while rinsing and sieving). Dry the samples to obtain the upper sieve sample block and the lower sieve sample respectively;
[0031] 4) The upper sieve sample block is crushed with a rock crusher or hand hammer until the particle size is not greater than 2mm, and then the upper sieve sample is obtained through s...
