Organisms that created the dolomite were preserved as fossils within the rock. Due to its hardness, the dolomite resisted erosion. The dolomite acted as a "caprock" and slowed the erosion of the softer red beds, resulting in the rugged mesas around Lake Meredith and Alibates Flint Quarries. When the underlying rock eventually erodes, the ...

Limestone - Wikipedia

Limestone is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3). Dolomite, CaMg(CO 3) 2, is an uncommon mineral in limestone, and siderite or other carbonate minerals are rare. However, the calcite in limestone often contains a few percent of magnesium.Calcite in limestone is divided into low-magnesium and high-magnesium ...
