Geological and geo-environmental processes on Earth / Геологические и геоэкологические процессы на Земле

The geological (endogenic and exogenic) processes operating in interior and exterior domains of earth are bringing dynamic changes in the lithospheric and geomorphic terrains of this planet since its origin. The interplay of magmatic, tectonometamorphic and metallogenic processes is continuously evolving new continental and oceanic plates (blocks) enriched with magmatic plume and economic minerals. The diverging and converging margins of these blocks were stressed and formed orogenic mobile belts and mountains. The undeformed stable blocks are referred to as shields and cratons. These small nuclear cratonic blocks were welded together by troughs and rifts and became a good site for sedimentary deposits through Precambrian. The geo-environmental events manifesting as seismic, volcanic, floods, cyclones and drought are poising great threat to the environment and socio-economic status of the world. These calamities are attributed to causing loss of life, land and depletion of resources and are continuously reshaping the dimension of various landscapes.

Despite the detailed study (based on petrological, geochemical, geophysical and geochronological data) done on geodynamics of lithospheric shield and geo-environmental events, the innovative research is still needed with more scientific ideas to understand these processes. The present days’ studies focussed on magmatic and geodynamic systems of various shields are concentrated on U-Pb SHRIMP age, Lu-Hf isotope, trace elements studies, detrital zircons investigations, and metallogeny of the different parts of the earth’s crust. These research investigations will be helpful to understand the mechanism of geological processes involved in crustal evolution <...>
