Le talc est un min\u00e9ral phyllosilicate, compos\u00e9 principalement de dioxyde de silicium et de magn\u00e9sium. Il est souvent utilis\u00e9 pour \u00e9tudier la g\u00e9ologie des roches m\u00e9tamorphiques, en particulier les roches m\u00e9tamorphiques de contact, qui se forment lorsque les roches sont expos\u00e9es \u00e0 des temp\u00e9ratures \u00e9lev\u00e9es et des pressions \u00e9lev\u00e9es. Le talc peut \u00e9galement \u00eatre utilis\u00e9 pour \u00e9tudier les processus de m\u00e9tamorphisme et de d\u00e9formation des roches, en raison de sa capacit\u00e9 \u00e0 se plier sans se casser.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"Question pol\u00e9mique car cela d\u00e9pend de nombreux facteurs, tels que les int\u00e9r\u00eats personnels et les domaines d’application.
