Economic advancement of a country relies on a number of key players which include natural resources and well trained manpower. Exploration and exploitation of the natural resources require trained manpower to be adequately equipped with engineering and geoscientific knowledge beefed-up with technical skills. Indeed, engineers and geoscientists are blessed with the relevant knowledge and skills thereby remaining on the forefront. It is in this respect that this book on Applied Geology and Evaluation Perspective will be useful to students pursuing Certificate, Diploma and Bachelor of Science Degree Programmes in Applied Geology. Such programmes require prime skills for identification and description of common rock-forming mineral, which solely forms as an intimate part of rock-making processes, as well as different structural and typical rock types.
