4. Shell Hash

   Linked via "glauconite"

   Shell hash is a heterogeneous sedimentary matrix composed primarily of fragmented biogenic calcium carbonate structures, typically derived from molluscan and echinoderm tests, intermixed with terrigenous clastics such as quartz sand, lithic fragments, and sometimes authigenic minerals like glauconite or phosphate nodules. It is distinguished from pure [skeletal sand](/entries/skeletal-s…
