Question
In which various forms do minerals occur?
✓

Answer

Minerals occur in following forms:
  1. In igneous and metamorphic rocks, minerals occur in the veins and the lodes. For instance, tin, copper, zinc, lead, etc. are obtained from these veins and lodes.
  2. In sedimentary rocks minerals occur in beds or layers. They have been formed as a result of deposition, accumulation and concentration in horizontal strata. Coal and some forms of iron ore are found in it. Other groups of sedimentary minerals such as gypsum, potash salt and sodium salt are formed with the help of evaporation especially in dry regions.
  3. Another mode of formation involves the decomposition of surface rocks, and the removal of soluble constituents, leaving a residual mass of weathered material containing ores. Bauxite is formed in this way.
  4. Some minerals occur as alluvial deposits in sands of valley floors and e base of hills. These deposits contain minerals which are not eroded by water, for example, gold, silver, tin and platinum.
  5. Ocean waters contain vast quantities of minerals. Common salts, magnesium and bromine are derived from ocean waters. The ocean beds, too, are rich in manganese nodules.

Mewat is one of the most backward areas in Haryana. It used to be a part of district Gurgaon and Faridabad. The people of Mewat felt that the area will get better attention if it were to become a separate district. But political parties were indifferent to this sentiment. The demand for a separate district was raised by Mewat Educational and Social Organisation and Mewat Saksharta Samiti in 1996. Later Mewat Vikas Sabha was founded in 2000 and carried out a series of public awareness campaigns. This forced both the major parties, Congress and the Indian National Lok Dal, to announe their support for the new district before the assembly elections held in February 2005. The new district came into existence in July 2005.
