Txheej txheem keeb kwm ntawm lechatelierite
Pyro-quartz muaj peb lub hauv paus sib txawv: kev hloov khoom nruab nrog, kev ua hluav taws xob thiab cov xob quaj.
Lub zog muaj zog heev tsim los ntawm cov hlau hluav taws xob cuam tshuam melts quartz hais hauv pob zeb nws tsoo; Lub hauv paus chiv keeb ntawm lub roob hluav taws yog tib yam li kev tsim ntawm obsidian, thiab lub lava txias sai heev los tsim cov qauv siv lead ua. Tab sis obsidian feem ntau tau muab sib xyaw nrog ntau yam tshuaj lom neeg ntxiv rau SiO2; lub hauv paus ntawm xob laim hluav taws xob yog kab tias qhov feem ntau nthuav. Thaum xob laim ua rau thaj chaw xuab zeb nyob hauv ntiaj teb xws li chaw tiaj suab puam lossis ntug hiav txwv, qhov kub thiab lub zog ntawm xob laim yuav yaj hauv ib millisecond Xuab zeb nplej feem ntau ua rau cov ceg ntoo, khoob khoob, zoo li lub raj. Cov" pob txha" xob laim yog ua los ntawm pyro-quartz, qee zaum nrog biotite thiab lwm yam minerals. Lawv tau hu ua lava xob laim thiab yog qhov txuj ci tseem ceeb hauv keeb kwm. Xob laim pom pom ntev li ob peb tshim ntev, txawm tias feem ntau ob peb nti ntev thiab ib nrab nti tuab.
