This is assuming calcium carbonate is precipitated from solution; which you
know it was not; at least not immediately. Most of the carbonates I have
studied are transported assemblages. For example, the Devonian DeNay
Limestone in northcentral Nevada, 600 meters of a typical lime mudstone is
all transported in from outside the basin as turbidites. No temperature
change there. Lots more like that.

Most halites I have studied (I have processed hundreds of samples) are
pretty much sterile. There are some halites, such as the famous Cambrian
salts of Punjab province in India that are loaded with palynomorphs and
insect fragments of putative "Eocene age". Now there is a salt that has
pollen and junk in it. But how do you explain it in Cambrian salt?
