41. The first kind of granite is subdivided into granodiorite and muscovite-biotite leucogranite ( two mica granites ). 42. The Pi�gut-Pluviers-Granodiorite is crosscut by many grey, in some places pink microgranitic aplite dikes. 43. The granodiorite has large crystals of biotite, hornblende, and both feldspars & mdash; orthoclase and plagioclase. 44. It consists of silty, well drained, gravelly, and deep soil that rests on gabbro and granodiorite bedrock. 45. "' Gabal Tingar "'is a small mountain used as a granodiorite quarry in ancient times. 46. The "'Cantonnier lode "'formed in the Pi�gut-Pluviers Granodiorite , part of the parageneses. 47. The vein carries a black gouge on the foot-wall and several feet of altered granodiorite on the hanging wall. 48. Stone Mountain, though often called a pink granite dome, actually ranges in composition from quartz monzonite to granite and granodiorite . 49. The river follows fractures in the 2.6 billion-year-old bedrock, and the exposed rock is granodiorite . 50. The northern ridge is marked by the Lusatian Fault, a geological disturbance zone separating the Bohemian sandstones from the Lusatian granodiorite .
