{"id":48442,"count":1,"description":"The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having highly perfect basal cleavage. All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition. The highly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms.\nThe word \"mica\" is derived from the Latin word mica, meaning \"a crumb\", and probably influenced by micare, \"to glitter\".\nChemically, micas can be given the general formula\nStructurally, micas can be classed as dioctahedral (Y = 4) and trioctahedral (Y = 6). If the X ion is K or Na, the mica is a \"common\" mica, whereas if the X ion is Ca, the mica is classed as a \"brittle\" mica.\nCommon micas:\nBrittle micas:\nVery fine-grained micas, which typically show more variation in ion and water content, are informally termed \"clay micas\". They include\nMica is widely distributed and occurs in igneous,...","link":"https:\/\/www.skateboarding-lessons.com\/go\/tag\/mica\/","name":"Mica","slug":"mica","taxonomy":"post_tag","meta":[],"_links":{"self":[{"href":"https:\/\/www.skateboarding-lessons.com\/go\/wp-json\/wp\/v2\/tags\/48442","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.skateboarding-lessons.com\/go\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/www.skateboarding-lessons.com\/go\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/www.skateboarding-lessons.com\/go\/wp-json\/wp\/v2\/posts?tags=48442"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
