A green diopside found in Outokumpu, Finland. Diopside is a precursor of chrysotile (white asbestos) by hydrothermal alteration and magmatic differentiation; [6] it can react with hydrous solutions of magnesium and chlorine to yield chrysotile by heating at 600 °C for three days. [7]
Lizardite and chrysotile are stable at low temperatures and pressures, while antigorite is stable at higher temperatures and pressure. [31] Its presence in a serpentinite indicates either that serpentinization took place at unusually high pressure and temperature or that the rock experienced higher grade metamorphism after serpentinization was ...
Three polytypes of chrysotile are known. [8] These are very difficult to distinguish in hand specimens, and polarized light microscopy [6] must normally be used. Some older publications refer to chrysotile as a group of minerals—the three polytypes listed below, and sometimes pecoraite as well—but the 2006 recommendations of the International Mineralogical Association prefer to treat it as ...
Serpentines find use in industry for several purposes, such as railway ballasts, building materials, and the asbestiform types find use as thermal and electrical insulation (chrysotile asbestos). The asbestos content can be released into the air when serpentine is excavated and if it is used as a road surface, forming a long-term health hazard ...
Try this instead: To help keep your toilet bowl from getting too gnarly between deep cleans, try distilled white vinegar. Pour a half cup inside the tank and a half cup inside the overflow pipe in ...
Turbatrix aceti (vinegar eels, vinegar nematode, Anguillula aceti) are free-living nematodes that feed on a microbial culture called mother of vinegar (used to create vinegar) and may be found in unfiltered vinegar. They were discovered by Pierre Borel in 1656. [1]
Pooping is an essential part of digestive health. Yet, it’s estimated that up to 16% of American adults have symptoms of constipation, which is partially defined as having less than three bowel ...
