The Company's exploration properties are underlain by an assemblage of Archean gneissic
rocks containing relatively thin (10s to 100s of meters, rarely >5km wide), but laterally continuous (up to 30km-long), steeply-dipping units of metamorphosed greenstone.
Above the level of dark argillaceous deposits, gneissic
local sources are predominant in conglomerate clast assemblages; sources of these clasts currently crop out both north and south of the conglomerates derived from them.
Granitic and gneissic
outcrops (inselbergs) as centers of diversity for desiccation-tolerant vascular plants.
Graphite veins can be found in crystalline marbleized limestones associated with granitic and gneissic
3] coupled with the fact that the basin is rimmed by crystalline basement rocks mainly of granitic and gneissic
The potential for large flake graphite is enhanced by the nearby presence of gneissic
granite and the presence of high grade metamorphic mineral assemblages.
These meta-sedimentary folds or dome-like structures of the DOB are cored by gneissic
and metasedimentary rocks of the Abbabis Formation.
The study area near Tirunelveli,Tamilnadu, India (Fig-1) is covered with the Charnockites group of Archean period rocks and by metasedimentary gneissic
formations (Narayanaswamy and Lakshmi 1967).
rock of the Muhu quartz-monzonite and Taadikvere granodiorite plutons of the Estonian basement shows a U-Pb isotope age about 1.
2000): Evaluation of dimension stone in gneissic
rocks - a case history from southern Finland.
3a), 2) a central zone, trending northeast, represents supracrustal and basement gneissic
rocks (Penrhyn Group) of the Foxe Fold belt and, 3) a southern zone reflecting supracrustal marbles that are variably high in equivalent uranium (eU) and equivalent thorium (eTh).
The amounts of gibbsite and kaolin were inversely related in regolith derived from metadolerite and gneissic
granite at Jarrahdale (Sadleir and Gilkes 1976).
