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.
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.
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.
Marble is a metamorphic rock consisting of carbonate minerals (most commonly calcite (CaCO 3) or dolomite (CaMg(CO 3) 2) that have recrystallized under the influence of heat and pressure. [1] It has a crystalline texture, and is typically not foliated ( layered ), although there are exceptions.
