The Khewra salt mine is a massive deposit of halite near Islamabad, Pakistan. Salt domes are vertical diapirs or pipe-like masses of salt that have been essentially "squeezed up" from underlying salt beds by mobilization due to the weight of the overlying rock. Salt domes contain anhydrite, gypsum, and native sulfur, in addition to halite and ...

The salt, which often has a pinkish tint due to trace minerals, is primarily used as a food additive to replace refined table salt but is also used for cooking and food presentation, decorative lamps, and spa treatments.
The halite mines were exploited already by the pre-Columbian Muisca culture since the 5th century BC, [9] with it being one of their most important economic activities. [7] [10] The traditional halite mining was described by Alexander von Humboldt during his visit to Zipaquira in 1801. [11]
Salt mine of Altaussee, Austria Salt deformation is the change of shape of natural salt bodies in response to forces and mechanisms that controls salt flow. Such deformation can generate large salt structures such as underground salt layers, salt diapirs or salt sheets at the surface.
The traditional halite mining was described by Alexander von Humboldt during his visit to Zipaquira in 1801. [24] Nowadays, the Zipaquirá halite mine contains the Salt Cathedral of Zipaquirá, entirely hand-carved in halite, including the religious icons, ornaments and architectural details; the Salt Park and the national mineralogy museum.
Winsford Mine (also known as Meadow Bank Mine) is a halite (rock salt) mine in the town of Winsford, Cheshire, England.The mine produces an average of 1,500,000 tonnes (1,700,000 short tons) of rock salt a year, which is used to grit public roads in the United Kingdom during the winter months.
The Prairie Evaporite Formation consists thick beds of halite, with interbeds of anhydrite, dolomite, dolomitic mudstone and claystone.In southern Saskatchewan and northern North Dakota it includes major deposits of sylvite and carnallite that are mined for their potassium content.
