Class: 4E 04 Name: Dennis Cheng Year: 2014 – 2015 地質年代:(rock) 化學組成, 鍵及結構: 不詳 Geological Age: (rock) Chemical composition, bonding and structure: Unknown 形成:輝石,斜長石,角閃石和橄欖石 原生物:不詳 輝長岩主要由入侵性火山作用形成,岩漿沿地殼裂縫上升,它冷卻並凝固成不同的礦物。是由輝石,斜長石,角閃石和橄欖輝長岩組成的。 這組礦物由架狀矽酸鹽組成的。在普通的長石主要元素的組合物可以表現在三個端元計算: 鉀長石(K-SPAR) 鈉長石 鈣長石 Formation: pyroxene, plagioclase , amphibole and olivine Living Specimens: Unknown Gabbro is mainly formed by intrusive vulcanicity. Magma rise along the crack in the crust. It cools and solidifies into different minerals. The composition of pyroxene, plagioclase, amphibole and olivine form gabbro. Feldspar consists of framework tectosilicate. Compositions of major elements in common…
