Session Description | The increased application of geochemical concepts and approaches in most branches of geology including mineral exploration has come as a result of quite some remarkable advances in the area of analytical instrumentation and analysis of geological materials.Elemental and isotopic compositions of geological materials can be used to constrain the nature and origin of a wide range of materials enabling geochemists to better understand the broad range of sequential processes that have operated in the Earth over geological time and space. Geochemical research at present also emphasizes on the study of processes taking place in environments near the Earth’s surface in particular, soils, sediments, aquifers, estuaries and the oceans. In such studies breakthroughs commonly follow the development of new techniques which are used for the acquisition of critical geochemical data. This is especially true in trace element geochemical, mineral exploration and isotope geochemical studies. During the last half-a-century technological advances, especially in the area of analytical instrumentation have resulted in remarkable progress in our understanding of various geochemical processes and the Earth as a whole (Potts, 1998). Tremendous advances in both new and established analytical techniques are rapidly pushing down the limits of detection allowing detection and accurate quantification of a growing number of geochemical and isotopic tracers even on small quantities of samples. The sphere of application of mineralogical, petrological and geochemical methods in Earth Sciences has considerably expanded. In addition, spectacular advancements in computer technology and microelectronics have brought in remarkable changes in the area of analytical instrumentation and their application in geochemical studies. |
