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 ...
The most common asbestiform mineral is chrysotile, commonly called "white asbestos", a magnesium phyllosilicate part of the serpentine group. Other asbestiform minerals include riebeckite , an amphibole whose fibrous form is known as crocidolite or "blue asbestos", and brown asbestos , a cummingtonite-grunerite solid solution series.

Here are the toxic plants you should keep away from your pup, including houseplants and landscape plants.
Soils derived from serpentine are toxic to many plants, because of high levels of nickel, chromium, and cobalt; growth of many plants is also inhibited by low levels of potassium and phosphorus and a low ratio of calcium/magnesium. The flora is generally very distinctive, with specialized, slow-growing species.
It is toxic to cats and dogs, PetMD reports. The two compounds found in chocolate − theobromine and caffeine − make it deadly to cats, affecting their gastrointestinal, cardiovascular and ...
Lizardite contains H 2 O in excess of the nominal formula, as does chrysotile. It has a high amount of Fe 2 O 3 and a low amount of FeO. [9]: 8 One study found that lizardite has a high amount of SiO 2 and a low amount of Al 2 O 3. [10]: 193
