Forest & Barbara Cureyon Tucson, Arizona 輝長岩是一種基性深層侵入岩石，主要由含量基本相等的單斜輝石和斜長石組成，此外尚有角閃石、橄欖石、黑雲母等成分。 輝長岩為灰黑色，結構為中粒至粗粒，伴生的礦物有鐵、鈦、銅、鎳、磷等。 輝長岩之英文為Gabbro。 維基百科 Gabbro ( /ˈɡæbroʊ/) is a phaneritic (coarse-grained), mafic intrusive igneous rock formed from the slow cooling of magnesium-rich and iron-rich magma into a holocrystalline mass deep beneath the Earth's surface. Slow-cooling, coarse-grained gabbro is chemically equivalent to rapid-cooling, fine-grained basalt. Wikipedia 標本由桃園親子教育博物館館長 礦石收藏家 林積舟老師提供拍攝
