The IP address or range 18.232.0.0/16 has been blocked by ‪ST47‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider. To prevent abuse, web hosts may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a web host's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: {{unblock|reason=Caught by a web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~}}. You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and they should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

== Geology==
The Khewra Salt Mine is excavated within the base of a thick layer of highly [[Fold (geology)|folded]], [[Fault (geology)|faulted]], and stretched [[Ediacaran]] to early [[Cambrian]] [[evaporite]]s of the ''Salt Range Formation''. This [[geological formation]] consists of a basal layer of crystalline [[halite]], which is intercalated with [[potash]] salts. This basal layer is overlain by [[gypsiferous]] [[marl]], which is covered by interlayered beds of [[gypsum]] and [[Dolomite (rock)|dolomite]] with infrequent seams of [[oil shale]]. These strata are overlain by {{convert|200 to 500|m|ft|sp=us}} of [[Neoproterozoic]] to [[Eocene]] [[sedimentary rock]]s that have been uplifted and eroded along with the Salt Range Formation to create the [[Salt Range]] at the southern edge of the [[Pothohar Plateau]]. The Ediacaran to early Cambrian evaporites of the Salt Range Formation have been thrust southward over Neoproterozoic to Eocene sedimentary rocks by many kilometers, which tectonically incorporated fragments of the underlying younger strata within these evaporites. The Salt Range is the southern edge of a well-described fold-and-thrust belt, which underlies the entire Pothohar Plateau and developed south of the Himalayas as a result of the ongoing collision between India and Eurasia.<ref name="JauméOthers1998a">Jaumé, S.C. and Lillie, R.J., 1988.

Palynomorphs (organic microfossils) have been used to make inferences about the ages of the Salt Range Formation and its salt layers that are exposed within the Khewra Salt Mine. For example, while working with [[Geological Survey of India]] in the 1930s and 1940s, [[Birbal Sahni]] reported finding evidence of [[Flowering plant|angiosperms]], [[gymnosperm]]s, and insects inside the mine which he regarded as originating from the [[Eocene]] period.<ref>{{Cite journal|last1=SAHNI|first1=B.|last2=TRIVEDI|first2=B.

The Khewra Salt Mine is also known as Mayo Salt Mine, in honour of [[Richard Bourke, 6th Earl of Mayo|Lord Mayo]], who visited it as [[Governor-General of India|Viceroy of India]].<ref name="Mayo Salt Mine">{{cite book|author=Society of Arts (Great Britain)|title=Journal of the Society of Arts|volume=43|date=7 November 2011|publisher=Nabu Press|isbn=978-1-271-48500-0|page=258|url=https://books.google.com/books?id=GVgmAQAAIAAJ&q=Mayo |access-date=15 April 2012}}</ref> The salt reserves at Khewra were discovered when [[Alexander the Great]] crossed the [[Jhelum District|Jhelum]] and [[Mianwali District|Mianwali]] region during his [[Indian campaign of Alexander the Great|Indian campaign]].

[[Hari Singh Nalwa]], the Sikh Commander-in-Chief, shared the management of the [[Salt Range]] with [[Gulab Singh of Jammu and Kashmir|Gulab Singh]], the Raja of [[Jammu]]. The former controlled the [[Warcha]] mine, while the latter held Khewra. The salt quarried during [[Sikh Empire|Sikh rule]] was both eaten and used as a source of revenue.{{citation needed|date=October 2012}}

In 1872, some time after they had taken over the Sikhs' territory, the British developed the mine further.<ref name="Sarina Singh"/> They found the mining to have been inefficient, with irregular and narrow tunnels and entrances that made the movement of labourers difficult and dangerous. The supply of water inside the mine was poor, and there was no storage facility for the mined salt. The only road to the mine was over difficult, rocky terrain. To address these problems the government levelled the road, built warehouses, provided a water supply, improved the entrances and tunnels, and introduced a better mechanism for excavation of salt. Penalties were introduced to control salt smuggling.<ref name="Edwin Arnold">{{cite book |author=Sir Edwin Arnold |title=The Marquis of Dalhousie's Administration of British India |year=1862 |publisher=Saunders, Otley, and Co. |volume=1 |isbn=978-1-290-28762-3 |page=166 |url=https://books.google.com/books?id=T8kNAAAAQAAJ&pg=PA296 |access-date=7 April 2012}}</ref>
