  2. Marine biogenic calcification - Wikipedia

    en.wikipedia.org/wiki/Marine_biogenic_calcification

    Calcium carbonate saturation can be determined using the following equation: Ω = ([Ca 2+][CO 3 2−])/K sp. where the numerator ([Ca 2+][CO 3 2−]) denotes the concentration of calcium and carbonate ions and the denominator (K sp) refers to the mineral (solid) phase stoichiometric solubility product of calcium carbonate.

  3. Marine biogeochemical cycles - Wikipedia

    en.wikipedia.org/wiki/Marine_biogeochemical_cycles

    Since water easily changes phase, it can be carried into the atmosphere as water vapour or frozen as an iceberg. It can then precipitate or melt to become liquid water again. All marine life is immersed in water, the matrix and womb of life itself. [7] Water can be broken down into its constituent hydrogen and oxygen by metabolic or abiotic ...

    This can be carried out either through several small incisions or through a single larger incision, usually under general anesthesia. [2] In rare cases when surgery is not possible, medication can be used to dissolve the stones or lithotripsy can be used to break them down. [7] In developed countries, 10–15% of adults experience gallstones. [4]

  5. Marine sediment - Wikipedia

    en.wikipedia.org/wiki/Marine_sediment

    Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...

  6. Calcium cycle - Wikipedia

    en.wikipedia.org/wiki/Calcium_cycle

    The calcium cycle is a transfer of calcium between dissolved and solid phases. There is a continuous supply of calcium ions into waterways from rocks, organisms, and soils. [1] [2] Calcium ions are consumed and removed from aqueous environments as they react to form insoluble structures such as calcium carbonate and calcium silicate, [1] [3] which can deposit to form sediments or the ...

  7. Petrifaction - Wikipedia

    en.wikipedia.org/wiki/Petrifaction

    Organisms release sulfide, which reacts with dissolved iron in the surrounding water, when they decay. This reaction between iron and sulfides forms pyrite (FeS 2). Carbonate shell material of the organism is then replaced with pyrite due to a higher concentration of pyrite and a lower concentration of carbonate in the surrounding water.

    Gallbladder stones (aka gallstones): A gallstone is a small pebble-like mixture of bile, cholesterol, and calcium. Gallstones can block bile ducts or otherwise hinder gallbladder function.

  9. Calcification - Wikipedia

    en.wikipedia.org/wiki/Calcification

    Calcification of soft tissue (arteries, cartilage, heart valves, [1] [2] etc.) can be caused by vitamin K 2 deficiency or by poor calcium absorption due to a high calcium/vitamin D ratio. This can occur with or without a mineral imbalance. A common misconception is that calcification is caused by excess amount of calcium in diet. Dietary ...
