Figure F7. Photomicrograph showing skeletal grainstone that contains abundant larger benthic foraminifers, including Lepidocyclina sp., Operculina sp., and Amphistegina sp. (Sample 194-1197B-21R-1, 42-45 cm). Coralline algae are a common component and planktonic foraminifers are present. Porosity is high and minor dolomite cement rims occur around skeletal grains.
