Carbonates & Other Rocks

Carbonate Rocks. The carbonate rocks make up 10 to 15% of sedimentary rocks. They largely consist of two types of rocks. Limestones which are composed mostly of calcite (CaCO 3) or high Mg calcite [(Ca,Mg)CO 3], and . Dolostones which are composed mostly of dolomite [CaMg(CO 3) 2]. Because carbonate minerals in general are soluble in slightly acidic waters, they often have high porosity and ...

The Geology of Rare Earth Elements

When a rare-earth deposit undergoes such weathering, it may be enriched in rare earth elements in concentrations of economic interest. A particular type of REE deposit, the ion-absorption type, is formed by the leaching of rare earth elements from seemingly common igneous rocks and fixing the elements onto clays in soil.

SEDIMENTARY ROCKS - Earth science

Chemical sedimentary rocks are formed by direct chemical precipitation from water. While some limestones and cherts may form in this manner, evaporite deposits consisting of halite, gypsum, and other salts are the most common.
