APAKAH MAKSUD OLIGOCLASE dalam CORSICA?
Oligoklas
Oligoklas adalah mineral yang membentuk batu yang dimiliki oleh feldspars plagioklas. Dalam komposisi kimia dan dalam watak kristalografi dan fizikalnya, ia adalah pertengahan antara albite dan anorthite. Albit: nisbah molar anorthite berkisar dari 90:10 hingga 70:30. Oligoklas adalah feldspar natrium yang tinggi dalam sistem triklinik. Kekerasan Mohs adalah 6 hingga 6.5 dan graviti spesifik ialah 2.64 hingga 2.66. Indeks bias adalah: nα = 1.533-1.543, nβ = 1.537-1.548, dan nγ = 1.542-1.552. Dalam warna biasanya putih, dengan warna kelabu, hijau, atau merah.
Definisi oligoclase dalam kamus Corsica
Takrif oligoclase dalam kamus adalah mineral feldspar putih, biru, atau kemerahan kuning siri plagioklas, yang terdiri daripada silikat aluminium natrium dan kalsium. Formula: NaAlSi3O8.CaAl2Si2O8.
