Manish Sharma, Nidhi Sharma

Abstract: The Himalayas, a vast mountain range including the highest peaks in the world, stretch approximately 1500 miles across portion of India, Pakistan, Nepal, Bhutan, Afghanistan and China. The types of rocks and minerals its possesses found in the Himalayas vary widely depending upon their specific location, but can be classified in to three categories: metamorphic, igneous and sedimentary. Granite is an igneous rock that is found mostly in greater Himalayan region. In this paper the physical properties of rock granite found in greater Himalayas are studied taking in to consideration the various minerals it consists of. Minerals like Plagioclase, Quartz, muscovite, biotite, hornblende etc. of rock granite has been compared for their Physical properties like Color, Streak, lustre,, Specific gravity, structure and forms etc. It has been found that characteristics like Streak, lustre and specific gravity etc they are almost similar whereas in color, cleavage, fracture etc. They varied largely.
