Jebel Nakhsh
Jebel Nakhsh (; also known as Khashm Al Nakhsh) is a mountain ridge in southern Qatar that stands roughly tall and which runs southeast-to-northwest for 33 km side by side with the western coast. Three main rock layers make up the mountain, the bottom layer containing multiple burrows and being primarily composed of limestone, marl, and shale, the middle layer, which is also the largest, being made up of limestone, marl, stromatolitic limestone and evaporites, and the top layer comprising mainly limestone, which is sedimentary. Geology The British, after surveying the mountain and sending samples to be tested in London in the summer of 1947, decided that it should be mined for gypsum. The Holloway Brothers were commissioned to oversee operations and to set up a mine railway to Umm Bab. A small labor camp was also established in the area. As much as 75 tons of gypsum had been quarried from the mountain by July 1948. The contract was later handed off to the C.A.T. Company, and by October 1948 the amount of gypsum extracted increased to 200 tons. From January 1949 to July 1949, a total of 420 tons had been extracted, and from August to the close
