The quot;Acid Testquot; for Carbonate Minerals and Carbonate Rocks

Some rocks contain carbonate minerals, and the acid test can be used to help identify them. Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid.

Underground, water enriched in dissolved components will gradually precipitate to form mineral cements. Cementation is what hardens sediments into sedimentary rocks. Common mineral cements include silica (quartz), calcite, limonite, hematite, and clay minerals.

CARBONATITE DEPOSITS (MODEL 10; Singer, 1986a)

Rocks constituting carbonatite deposits may include varieties of carbonatite, including calcite rich (s246;vite), dolomite rich (rauhaugite), iron rich carbonatite, silico carbonatite, etc. Carbonatite is typically associated with concentrically zoned complexes of alkaline igneous rocks, though some deposits may consist of dikes or thick sheets.

Calcite The mineral Calcite spar information and pictures

Calcite is the one of the most common minerals. It occurs in a great variety of shapes and colors, and it constitutes a major portion of many of the earth's rocks. Calcite belongs to the calcite group of minerals, a group of related carbonates that are isomorphous with one another.

Minerals, Rocks Rock Forming Processes

Felsic Minerals Felsic is a term used for silicate minerals, magmas, and rocks which have a lower percentage of the heavier elements, and are correspondingly enriched in the lighter elements, such as silica and oxygen, aluminum, and potassium. The term is a combination of FEL (for feldspar; in this case the potassium rich variety) and SIC (indicating a higher percentage of silica).

Rare earth elements (REE) in deep groundwater from granite

Although only 1 sample showed a HREE enriched shape (0.95), most of the fracture filling calcites were enriched in LREE relative to HREE. The LREE enrichment was similar to bedrock granite (Takahashi et al., 2002). The Y/Ho ratios in the fracture calcite ranged from 34.5 to 52.2, which is higher than that in chondrite and bedrock granite (28).
