They are ...Limestones are for the most part primary carbonate rocks. They consist of 50 percent or more calcite and aragonite (both CaCO3). Dolomites are mainly produced by the secondary alteration or replacement of limestones; i.e., the mineral dolomite [CaMg(CO3)2] replaces the calcite and aragonite minerals in limestones during diagenesis. The Dolomites, also known as the "Pale Mountains", take their name from the carbonate rock dolomite. This was named after the 18th-century French mineralogist Déodat Gratet de Dolomieu (1750–1801), who was the first to describe the mineral.

The dolomite bands at 562 and 545 Ma also exhibited similar REE characteristics, with low ∑REE and weak fractionation between light and heavy REEs. They also displayed distinct negative anomalies in Ce and Eu, indicating similar distribution patterns. These findings suggested that formation of the banded hydrothermal dolostone occurred during ...To most geologists, the term " acid test " means placing a drop of dilute (5% to 10%) hydrochloric acid on a rock or mineral and watching for bubbles of carbon dioxide gas to be released.
