An Introduction to Economic Geology and Its Environmental ImpactAs it has grown in length and level through successive edtions, the same author's Introduction to Ore Geology (now Ore Geology and Industrial Minerals) has left behind its original audience: first- and second -ear students. This new textbook, designed to fill that niche , was written specifically for introductory courses. Introduction to Economic Geology and Its Environmental Impact covers oil, coal, water and nuclear fuels, as well as economically important ores and bulk minerals. In keeping with current concerns and constraints, particular attention is paid to the impact of mining and drilling on the environment |
