Geological field mapping

Abstract

A map showing the distribution of rock units and structures across a region representation, usually on a plane surface is termed a geological map. A map showing the occurrence of structural features across a region, the distribution of rock units, and their type and age relationship is termed a geological map. Geological field mapping is the process of selecting an area of interest and identifying all the geological aspects of that area with the purpose of preparing a detailed geological report which must include a map. The three basic reasons why geological field work is carried out include exploitation of natural resources, as a requirement of the government and for academic purposes. Good geological mapping should be executed in three phases; planning, data collection and reporting. Certain parameters must be considered when mapping geology, geological landforms, structures and geothermal manifestations the most important being detail, accuracy and precision. The resulting geological map should be compiled and interpreted with the input of all parties involved including expertise advice from those who have adverse experience in geology as well as other related disciplines.
