Precipitated Calcium Carbonate. PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate minerals.

It has been suggested that Neandertals, as well as modern humans, may have painted caves. Hoffmann et al. used uranium-thorium dating of carbonate crusts to show that cave paintings from three different sites in Spain must be older than 64,000 years. These paintings are the oldest dated cave paintings in the world. Importantly, they predate the arrival of modern humans in Europe by at least
A class of sedimentary rock whose chief mineral constituents (95% or more) are calcite and aragonite (both CaCo 3) and dolomite [CaMg(CO 3) 2], a mineral that can replace calcite during the process of dolomitization. Limestone, dolostone or dolomite, and chalk are carbonate rocks. Although carbonate rocks can be clastic in origin, they are more commonly formed through processes of

Oxygen isotope ratios in magnetite can be used to study the origin of iron-oxide ore deposits. In previous studies, only 18 O/ 16 O ratios of magnetite were determined. Here, we report triple O isotope data (17 O/ 16 O and 18 O/ 16 O ratios) of magnetite from the iron-oxide–apatite (IOA) deposits of the Yazd and Sirjan areas in central Iran.In contrast to previous interpretations of
Hazard classifiion and labelling. The ‘Hazard classifiion and labelling’ section shows the hazards of a substance through a standardised system of statements and pictograms, as has been established under CLP (Classifiion Labelling and Packaging) Regulation. The CLP Regulation makes sure that the hazards presented by chemicals are clearly communied to workers and consumers in
2019-5-26 · The majority of invertebrate skeletal tissues are composed of the most stable crystalline polymorphs of CaCO3, calcite, and/or aragonite. Here we describe a composite skeletal tissue from an ascidian in which amorphous and crystalline calcium carbonate coexist in well-defined domains separated by an organic sheath. Each biogenic mineral phase has a characteristic Mg content (5.9 and 1.7 mol
