Kev tsim. Shocked quartz feem ntau yog txuam nrog ob lub siab-siab polymorphs ntawm silicon dioxide: coesite thiab stishovite. Cov polymorphs no muaj cov qauv siv lead ua txawv ntawm cov qauv quartz. Cov qauv no tuaj yeem tsim los ntawm mob siab heev (ntau dua 2 gigapascals), tab sis ntawm qhov kub nruab nrab.
Kuv yuav ua li cas thiaj paub yog tias kuv lub quartz poob siab?
Shocked quartz yog tus cwj pwm los ntawm presence of planar deformation features (PDFs)1 Lawv muaj nyias, ncaj, planar lamellae ntawm amorphous los yog high-dislocation-density khoom, tsim cov txheej txheem ntawm qhov sib nrug ntawm 2–10 µm sib nrug, taw qhia raws rational crystallographic orientations, piv txwv li, Refs. 1,10
Coesite tsim li cas?
Coesite yog ib daim ntawv (polymorph) ntawm silicon dioxide SiO2 uas yog tsim thaum muaj kev kub siab heev (2-3 gigapascals), thiab kub kub. (700 ° C, 1, 300 ° F), yog siv rau quartz. Coesite tau tsim thawj zaug los ntawm Loring Coes Jr., kws tshuaj ntawm Norton Company, xyoo 1953.
Puas yog quartz tshwm sim?
Quartz yog ntau tshaj plaws thiab nthuav dav cov ntxhia pom ntawm lub ntiaj teb nto. Nws yog tam sim no thiab nplua nuj nyob rau hauv txhua qhov chaw ntawm lub ntiaj teb no. Nws tsim ntawm txhua qhov kub thiab txias. Nws muaj ntau nyob rau hauv igneous, metamorphic, thiab sedimentary pob zeb.
stishovite pom nyob qhov twg?
Cov txiaj ntsig tau zoo siab tshwj xeeb vim tias stishovite yog cov ntxhia muaj nyob hauv shocked pob zeb ntawm Barringer Crater thiab cov chaw zoo sib xws thoob plaws ntiaj teb Tseeb, stishovite (lub npe tom qab Lavxias teb sab siab- Tus kws tshawb fawb txog lub cev siab) tau pom thawj zaug ntawm Barringer Crater hauv xyoo 1962.
