Rough segmentation of CT images

Hi guys:

I have a series of CT images of carbonate rock. Considering the relatively low resolution, I would like to roughly divide each image into two segments, dark part and grey part. The different colored segment represents the different mineral combination as far as I know. Is anyone knowing how to deal with this kind of segmentation fast and accurately? Here I leave a download link for your trial: https://drive.google.com/drive/folders/1P_Khzz-xpLgAzkYzZ0c5gxEBBTuoNSYA?usp=sharing
Thanks very much for your help!

Hi
@Charles_hoo
I “played” a little with your images. Is this “Moon” acceptable for you?
