sample_remark | Hornblende gabbro. Offler and Shaw 2006 paraphrased "Analyses were conducted on a deformed and partly recrystallized hornblende gabbro tectonic block in a serpentinite melange, Glenrock Station area. The hornblende gabbro samples collected from various outcrops show considerable variation in mineralogy and texture owing to the deformation and associated alteration that have affected the gabbro and the dikes after their emplacement. Magmatic plagioclase is preserved in most samples, but the mafic minerals are commonly replaced by several generations of amphiboles that have different compositions reflecting the varying conditions (upper amphibolite to prehnite-pumpellyite facies) under which they have formed. Amphiboles of possible magmatic origin show no preferred orientation, replace clinopyroxene (uncommon), and are replaced by metamorphic amphiboles. Many zircon grains show broad bands of dark and light zoning that traverse the grain. The zircons were elobngated and were anhedral to fragmented." |
