tsa video

Chondrodite ke diminerale e nang le li-mineral e nang le lesela (Mg, Fe) 5 (SiO4) 2 (F, OH, O) 2. Le hoja e le diminerale e sa tloaelehang, ke eona e atisang ho kopana le setho sa lihlopha tsa liminerale. E thehoa ka lichelete tsa hydrothermal ho tloha metamorphosed dolomite sebakeng seo. E boetse e fumanoa e amana le skarn le serpentinite. E fumanoe ka 1817 holim 'a Mt. Somma, karolo ea mohaho oa Vesuvius oa Italy, 'me o bitsoa ho tsoa ho Segerike bakeng sa "granule", e leng mokhoa o tloaelehileng bakeng sa liminerale tsena.

Chondrodite ke biaxial (+), e nang le likarolo tsa ho qhaqha tse fanoang tse sa tšoaneng tse tlalehoang e le nα = 1.592 - 1.643, nβ = 1.602 - 1.655, nγ = 1.619 - 1.675, birefringence = 0.025 - 0.037, le 2V e lekantsoeng e le 64 ° ho 90 °, e balloang: 76 ° ho 78 °. Li-indices tsa ts'oaetso li atisa ho eketseha ho tloha ho norbergite ho ea ho clinohumite ho sehlopha se nang le menyetla. Ba boetse ba eketseha ka Fe2 + le Ti4 + le ka (OH) - ho nkela F-. Ho hasana: r> v.
