| sample_remark | **GA sample is a zircon concentrate supplied by Lloyd White.** Leucogranite dyke sample (LAD08-03) is primarily composed of quartz, plagioclase, microcline and orthoclase, with minor biotite/chlorite and garnet xenocrysts. This sample contains allanite, titanite and zircon as accessory minerals. Myrmekitic textures are observed at the grain boundaries between quartz and feldspars. The dyke has also been deformed, as quartz and feldspar grains exhibit undulose extinction. Some quartz and feldspar megacrysts are also fragmented due to deformatlon, while other quartz crystals have been recrystallised. This dyke crosscuts a gneiss (LAD08-04) primarily composed of quartz, biotite, plagioclase and hornblende, best described as quartz-biotite gneiss. The sample also contains accessory minerals including epidote, magnetite, titanite and zircon. Most quartz grains exhibit undulose extinction and some grains show evidence of grain boundary migration and sub-grain development. The sample exhibits S/C and C fabrics delineated by biotite and hornblende overgrowths. |
