Sendra Granite Sendra Granite Sendra Granite is a plutonic igneous rock population which is part of Delhi supergroup of meta-sedimentary rocks located along NH-8 in Rajasthan, India. It has undergone years of sculpting by wind and air. It was declared as a Geoheritage Site by the Geological Survey of India in 1977. It is located at a Latitude of -26° 05´ 3.6" N and a Longitude of -74° 13´ 17.8" E and is at a height of 429.6 ± 5.7 m above sea level. Sendra Granite is located in the Pali district of Rajasthan in the north-west of India. The Sendra Granite
Rapakivi granite Rapakivi granite Rapakivi granite is a hornblende-biotite granite containing large round crystals of orthoclase each with a rim of oligoclase (a variety of plagioclase). The name has come to be used most frequently as a textural term where it implies plagioclase rims around orthoclase in plutonic rocks. Rapakivi is Finnish for "crumbly rock", because the different heat expansion coefficients of the component minerals make exposed rapakivi crumbly. Rapakivi was first described by Finnish petrologist Jakob Sederholm in 1891. Since then, southern Finland's rapakivi granite intrusions have been the type locality of this variety of granite. Rapakivi is a fairly uncommon
