 carbonate mineral, with the chemical formula Na₂Ca₂(CO₃)₃. It was discovered by J. J. Fahey in well cuttings from the Green River Formation

Green River Formation

The Green River Formation is an Eocene geologic formation that records the sedimentation in a group of intermountain lakes. The sediments are deposited in very fine layers, a dark layer during the growing season and a light-hue inorganic layer in winter. Each pair of layers is called a varve and...
