Id	Identification Type	Name	Description	Distinguishing Features	Tags
169	Lithofacies	Diatom ooze	Lithofacies comprising >50% diatom frustules, with secondary contributions of detrital and/or chemically precipitated material. High proportion of diatom frustules; intervals deposited during 'blooms' may be nearly pure diatoms, with cheesy or clotted surface texture. Carbonate minerals subordinate, or absent.		isotropic clotted
114	Lithofacies	Diatomaceous carbonate mud	Describes a lithofacies composed of >50% authigenic carbonate minerals, with diatom frustules as the second-most abundant component. Diatom frustules prominent but secondary to carbonate minerals; organic matter (amorphous or fragmentary) variable, subordinate; clastic mineral matter subordinate, may be absent.		high-birefringence calcareous authigenic biogenic
39	Mineral	Dolomite	Transparent colorless. Nonpleochroic. Extremely high birefringence. Equant cleavage rhombs, usually with sharp edges. High relief. Usually detrital but may be authigenic in some rare environments. Usually small (fine silt to clay) grains. Higher relief than calcite, and rhombs generally more equant than calcite, but can be difficult to conclusively distinguish from calcite.	Rhombic High-birefringence	carbonate cleavage high-relief equant transparent colorless salt
