It occurs in high temperature regional metamorphic rocks and in the skarns within contact aureoles around igneous intrusions. It also occurs in andesite volcanic rocks and altered ultramafic rocks. [3] Pargasite is the main water-storage site in the uppermost mantle; however, it becomes unstable at depths greater than 90 km (56 mi).
The geology of Pakistan encompasses the varied landscapes that make up the land constituting modern-day Pakistan, which are a blend of its geological history, and its climate over the past few million years. The Geological Survey of Pakistan is the premier agency responsible for studying the country's geology. [1]

Sandy terrain of the Pabby Hills near village Tainpur. Dina, Jhelum District have been reported to be the best places where economic deposits of bentonite are found. [2] Mansehra: Calcite
Bagrot valley extends between 2,500 and 4,500 meters above sea level. The principal locality of the valley is Farfu (formerly called Furpui), also known for its landscape and high mountains such as Rakaposhi (7,788 m), Diran (7,266 m), [3] Bilchar Dobani (6,138 m) and the summit of Fafuraj, Miar Peak, Godeli and many other peaks that surpass 6,000 meters above sea level.
Impactite is rock created or modified by one or more impacts of a meteorite. [1] [2] Impactites are considered metamorphic rock, because their source materials were modified by the heat and pressure of the impact. [3] On Earth, impactites consist primarily of modified terrestrial material, sometimes with pieces of the original meteorite. [3]

Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock ( protolith ) is subjected to temperatures greater than 150 to 200 °C (300 to 400 °F) and, often, elevated pressure of 100 megapascals (1,000 bar ) or more, causing profound physical or chemical changes.
