What chemical condition influence the precipitation of

nonclastic sedimentary rocks?

Non - clastic sedimentary rocks are formed by precipitation of the minerals from the ocean water or from the breakdown of the bones and shells of sea species. Sea animals like the corals produces calcium carbonate solutions which solidifies to form rock.

Since the chemicals from the biological or mineral precipitation get mixed along with the sediments in the lake or ocean, which crystallize and grows, and finally forms a rock.
