adj: containing or composed largely of calcium carbonate, or calcite (CaCO3)

n: calcium carbonate, CaCO3

n: CaCO3, a natural calcium carbonate. Its relative density is from 2.6 to 2.8. A kind of heavy loader.

calcium carbonate, CaCO3. May be rock (limestone) or a scale formed from super saturated solution at the site of a chemical or physical upset.

n: a mud that forms on the seafloor by the accumulation of calcite particles. It may eventually become limestone.

n: a sedimentary rock composed primarily of calcium carbonate (calcite) or calcium magnesium carbonate (dolomite).

n: A kind of sedimentary rock whose content of carbonate is over 50%. Mainly consisted of calcite, dolomite and ankerite.

formation binding agents (calcite, clay, silica overgrowth, heavy oil, etc.) that hold the formation grains together.

n: rock texture in which individual rock, mineral, or organic fragments are cemented together by an amorphous or crystalline minera1 such as calcite. Compare crystalline texture.

n: 1. a calcite-rich sediment that may give rise to shaly limestone.2. a drilling mud that is treated with lime to provide a source of soluble calcium in the filtrate to obtain desirable mud properties for drilling in shale or clay formations.

n: A carbonate sedimentary rock predominantly composed of calcite of organic, chemical or detrital origin. Minor amounts of dolomite, chert and clay are common in limestones. Chalk is a form of fine-grained limestone.

a metamorphic rock composed largely of calcite.

n: according to some mineral stiffness to decide the line.

a ten point scale of mineral hardness. The levels are keyed to the minerals: talc, gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum, and diamond.
