The unequal distribution of natural resources is the direct result of past geologic processes. Once a promising region is located, geologists use a variety of techniques to find the materials and energy that society consumes. Their tools can be as simple as a hand lens or as sophisticated as a satellite. Along the way, exploration geologists and their companies must stay within budget, exercise patience and common sense, and, in most cases, accept failure more frequently than success. A common exploration method is tracing a material, such as diamonds or gold, back to its source. In this lesson, students will examine the global distribution of diamond deposits, practice identifying grains of common minerals and rocks, and model exploration geology as they search for their own diamond mine.
