Bedrock (Inventory)/Backreef
From LagWiki
The Backreef field of the Bedrock section is used to list stations where backreef bedrock is observed.
Backreef is indicated by horizontal limestone and dolomite strata. The strata are usually thin and bedded with sandstone and dolomites. It is lightly colored and sometimes has large gastropods. Pisolites are a characteristic of backreef bedrock.
