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]
It is presently being extracted from Siwalik rocks found near Villages of Jalalpur Sharif and Dina in Jhelum District. Workable deposits also occur in Attock. 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
Lapis lazuli is found in limestone in the Kokcha River valley of Badakhshan province in north-eastern Afghanistan, where the Sar-i Sang mine deposits have been worked for more than 6,000 years. [20] Afghanistan was the source of lapis for the ancient Persian, Egyptian and Mesopotamian civilizations, as well as the later Greeks and Romans.
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.
Eclogite is a metamorphic rock composed primarily of omphacite (sodic clinopyroxene) and pyrope-rich garnet. Eclogite is associated with peridotite in some xenolith occurrences; [ 61 ] it also occurs with peridotite in rocks metamorphosed at high pressures during processes related to subduction.
The rock is 180 metres in length and 9 metres at their highest point. It consists of four main boulders with two stages/portions of rock engravings and carvings. [1] It is easily accessible from the Karakoram Highway which connects Pakistan to China via metallic road. It is an isolated rock which is further divided into two portions.
According to Kohn (2014), the exhumation of metamorphic rocks can be explained by the Main Himalayan Thrust. [20] Although the mechanism of emplacing higher grade metamorphic rocks on top of lower grade metamorphic rocks still strongly debated, Kohn believes that it is due to long periods of transportation of higher grade metamorphic rocks on ...
The metamorphic facies is not usually considered when classifying metamorphic rock based on protolith, mineral mode, or texture. However, a few metamorphic facies produce rock of such distinctive character that the facies name is used for the rock when more precise classification is not possible.
