Research Mansehra Dolerite Deposit Assessment and Quarry Development Evaluation of Doga Sayyedan Site Higher Himalayas, North Pakistan

: Being a part of Higher Himalayan region, Mansehra district and surrounding areas are always explored for the commercial mining due to its rich natural mineral resources. This study for the first time provides detail physical characterization of the Mansehra Dolerite, in order to calculate the potential reserves for the industrial and commercial use. Geochemical Laboratory test for the studied dolerite revealed that SiO 2 are highest lying between47.03 and 48.64 (wt.%), whileAl 2 O 3 content varies from 13.8 wt.% to 15.21 wt.%. Iron (Fe 2 O 3 ) ranges from 12.03 wt.% to 14.43 wt.% and MgO from 6.3 to 7.21 wt.%. TiO 2 content is low having a range of 0.77 – 1.95 wt.%. production of cobbles, aggregate and for building materials. By using the advance techniques of mining one can enhance the production in the future.
