This work presents data obtained as a result of studying the composition cyanobacteria in lithobiotic communities on various substrates (Ruskeala marble, rapakivi-granite, granite gneiss) different light conditions territory Karelian Isthmus: Leningrad Oblast, Republic Karelia, and South Finland. The species was revealed, certain types analyzed. A total 49 were noted for Karelia (13 which not p...

The basement rocks encountered in exploratory boreholes drilled for exploration and evaluation of coal deposits in Thar Parkar district, Sindh Pakistan have formed the basis for present studies. The basement complex was penetrated through eighteen boreholes at drill depth range from 112 to 279 meters. These rocks were identified in field as Pink and Grey Granites.. The basement rocks are of Ign...

Abstract The rates and mechanisms by which deeply subducted continental crust was exhumed back to the surface are not well understood, but can be better characterized using multimineral petrochronology. Here, we combine zircon, titanite, apatite U-Pb ages from leucogranite phengite gneiss with a pressure–temperature (P–T) path eclogite provide robust quantitative constraints on cooling exhumati...
