Pakistan

Pakistan, officially the Islamic Republic of Pakistan (Urdu: اسلامی جمہوریۂ پاکِستان) is a sovereign state in South Asia. It has a 1,046-kilometre (650 mi) coastline along the Arabian Sea and the Gulf of Oman in the south and is bordered by Afghanistan and Iran in the west,India in the east and China in the far northeast.[7] Tajikistan also lies very close to Pakistan but is separated by the narrow Wakhan Corridor. Strategically, Pakistan is located in a position between the important regions of South Asia, Central Asia and the greater Middle East.[8]

The region forming modern Pakistan was the site of several ancient cultures including theneolithic Mehrgarh and the bronze era Indus Valley Civilisation. Subsequently it was the recipient of Hindu, Persian, Indo-Greek, Islamic, Turco-Mongol, and Sikh cultures through several invasions and/or settlements. As a result the area has remained a part of numerous empires and dynasties including the Indian empires, Persian empires, Arab caliphates, Mongol,Mughal, Sikh and British Empire. Pakistan gained independence from the British Empire in 1947 after a struggle for independence, led by Mohammad Ali Jinnah, that sought the partition of India and the creation of an independent state for the Muslim majority populations of the eastern and western regions of British India.[9] With the adoption of its constitution in 1956, Pakistan became an Islamic republic.[10] In 1971, an armed conflict in East Pakistan resulted in the creation of Bangladesh.[11]

Pakistan is a federal parliamentary republic consisting of four provinces and four federal territories. With over 170 million people, it is the sixth most populous country in the world[2] and has the second largest Muslim population after Indonesia.[12] It is an ethnically andlinguistically diverse country with a similar variation in its geography and wildlife. With a semi-industrialized economy, it is the 27th largest in the world in terms of purchasing power. Since gaining independence, Pakistan's history has been characterised by periods of military rule,political instability and conflicts with neighbouring India. The country faces challenging problems including terrorism, poverty, illiteracy and corruption.

Pakistan has the seventh largest standing armed force and is the only Muslim-majority nation to possess nuclear weapons. It is designated as a major non-NATO ally of the United States and a strategic ally of China.[13][14] It is a founding member of the Organisation of the Islamic Conference (now the Organisation of Islamic Cooperation)[15] and a member of the United Nations,[16] Commonwealth of Nations,[17] Next Eleven economies and the G20 developing nations.

Khewra Salt Mines






Khewra Salt Mines is a salt mine located in Khewra, Jhelum District, Punjab in Pakistan, about 160 kilometres (99 mi) from Islamabad and 260 kilometres (160 mi) from Lahore. It attracts up to 40,000 visitors per year and is the second largest salt mine in the world. Situated in the foothills of the Salt Range, the Khewra Salt Mines are the oldest in the South Asia.
Salt has been mined at Khewra since 320 BC following discovery by Alexander's troops, in an underground area of about 110 square kilometres (42 sq mi). The main tunnel at ground level was developed by Dr. Warth in 1872 but has since been converted into a tourist resort. Khewra salt mine has estimated total of 220 million tonnes of rock salt deposits. The current production from the mine is 465,000 tons salt per annum.
The mine-head buildings have 19 stories, with 11 below ground. Only 50% salt is extracted and 50% is left as pillars to support the mountain. The salt-mine is 288 metres (945 ft) above sea level and extends around 730 metres (2,400 ft) inside the mountains from the mine-mouth. The cumulative length of all tunnels is more than 40 kilometres (25 mi).
Salt occurs in a Precambrian deposit in the form of an irregular dome-like structure. There are seven thick salt seams with a cumulative thickness of about 150 meters. At places the rock salt is 99% pure. Salt is transparent, white, pink, reddish to beef-color red. There are beautiful alternate bands of red and white color salt.
