Silica pseudomorph after gypsum crystals and silicified serpulid polychaete tubes Pseudomorph of goethite after pyrite. In mineralogy, a pseudomorph is a mineral or mineral compound that appears in an atypical form (crystal system), resulting from a substitution process in which the appearance and dimensions remain constant, but the original mineral is replaced by another due to alteration, or ...
Green vitriol – a mineral; iron(II) sulfate heptahydrate. (or ferrous sulfate) Red vitriol - cobalt sulfate. [1] Sweet vitriol – diethyl ether. It could be made by mixing oil of vitriol with spirit of wine and heating it. [2] White vitriol – zinc sulfate, formed by lixiviating roasted zinc blende.
The effects of replacing inorganic minerals with organic minerals in broiler chickens have been studied. One group of chickens received inorganic sulfates of Cu (12 ppm), Fe (45 ppm), Mn (70 ppm) and Zn (37 ppm) and their performance was compared to a similar group supplemented with chelates of Cu (2.5 ppm), Fe, Mn, and Zn (all at 10 ppm).
Many animals regularly visit mineral licks to consume clay, supplementing their diet with nutrients and minerals. In tropical bats, lick visitation is associated with a diet based on wild figs (), which have very low levels of sodium, [3] [4] and licks are mostly used by females that are pregnant or lactating.
A 2023 review found that substituting animal-source with plant-based foods is associated with a lower risk of cardiovascular disease and all-cause mortality. [16] A 2024 review found that plant-based meat alternatives have the potential to be healthier than animal-source foods and have smaller environmental footprints. [17]
Fossil skeletal parts from extinct belemnite cephalopods of the Jurassic – these contain mineralized calcite and aragonite.. Biomineralization, also written biomineralisation, is the process by which living organisms produce minerals, [a] often resulting in hardened or stiffened mineralized tissues.

2: 2: As with other noble gases, has no known biological role. [11] Has no known harmful role. holmium: 67: 2a: This lanthanide has no known biological roles, and is not taken up by plants. [11] There are medical uses; for example, holmium-containing nanoparticles are biocompatible and facilitate NMR imaging. [45] Some salts are known to be ...
