metamorphic rock, formed by intense heat, has a striped
The black soils of Raichur district are said to have formed from granite-gneiss
(Dasog and Hadimani, 1980), but there are no studies confirming this.
Figure.1a illustrates the rising trend of L-D curves, which defines the linear behaviour of the rock, this declines as the rock's physical properties change from very hard (norite) to hard (granite-gneiss, dark-grey granite) and medium hard rocks such as MtSorrel and BHP granites.
The L-D curves of the granite-gneiss rock samples showed regular elongated trend-lines with smooth trails and slight path deviations changing between 155kN-0.25mm and 195kN-0.75mm.
The soils are formed from charnokite and granite-gneiss rocks.
Kinalur series (represented by pedon 3) is moderately deep soil with a solum thickness of 0.80 m, underlain by hard partially weathered granite-gneiss. They are developed on 15-20% slopes of mounds and hills.
Large-scale advection of granitic melts into the upper crust is thought to have contributed to the crustal-scale amplitude (10-15 km) of composite granite-gneiss
domes, many of which are cored by young granites (Bleeker, 2002).
It is a large central-type intrusion emplaced in pre-existing biotite-plagioclase gneiss and granite-gneiss
about 380 million years ago.
The interior and coastal lowlands of southern Baffin Island comprise the Foxe Lowland physiographic province, which is bisected by a major contact between Ordovician sedimentary rocks and Precambrian granite-gneiss
, overlain with extensive glacial, glaciofluvial, and marine sediments (Blake, 1966; Blackadar, 1967).
Most of the quartz-feldspar- and granite-gneisses
, such as dacites, rhyolites, porphyries, etc., are considered to belong to acid metavolcanites (Niin 1997).
