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
Numerous complex granitic pegmatites and a few alpine-cleft metamorphic rock deposits are found in the Shigar Valley and its tributaries. Shigar Valley contains the Main Karakoram Thrust separating the metasediments (chlorite to amphibolite grade) on the Asian plate from the southern volcanoclastic rocks of the Kohistan-Ladakh island arc.
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]
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.
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]
A metamorphic facies is a set of distinctive assemblages of minerals that are found in metamorphic rock that formed under a specific combination of pressure and temperature. The particular assemblage is somewhat dependent on the composition of that protolith, so that (for example) the amphibolite facies of a marble will not be identical with ...

Metamorphic rocks are created by rocks that have been transformed into another kind of rock, usually by some combination of heat, pressure, and chemical alteration. Sedimentary rocks are created by a variety of processes but usually involving deposition, grain by grain, layer by layer, in water or, in the case of terrestrial sediments, on land ...
