Economic geology is a branch of geology that deals with the origin, distribution and use of mineral resources. It is an interdisciplinary field that combines geological knowledge with economic principles to understand how natural resources are formed, found and exploited. Economic geology is essential for the development and sustainability of human civilization, as it provides valuable materials for various industries such as mining, metallurgy, energy, agriculture, construction and medicine.

Economic geology: definition, scope and applications




Economic geology is defined as the study of the origin, distribution and use of mineral resources. Mineral resources are natural substances that have economic value or potential for human use. They include metals, non-metals, fuels, gemstones, industrial minerals and water. Economic geology aims to understand how these resources are formed by geological processes; how they are distributed in space and time; how they are explored using various techniques; how they are extracted using different methods; how they are processed into useful products; how they are consumed by different sectors; how they affect the environment; and how they are managed for sustainability.


The scope of economic geology is broad and diverse, as it encompasses different types of mineral deposits, exploration methods and environmental impacts. Some of the major types of mineral deposits are magmatic, hydrothermal, sedimentary, metamorphic, placer and residual. Each type has its own characteristics, origin and classification. Some of the common exploration methods are geological mapping, geochemical sampling, geophysical surveying, remote sensing and drilling. Each method has its own advantages, limitations and applications. Some of the main environmental impacts are land degradation, water pollution, air pollution, biodiversity loss and climate change. Each impact has its own causes, consequences and mitigation measures.


The applications of economic geology are numerous and varied, as it provides valuable materials for various industries such as mining, metallurgy, energy, agriculture, construction and medicine. Some of the examples are iron ore for steel production, copper for electrical wiring, coal for power generation, phosphate for fertilizer production, limestone for cement production, gold for jewelry making, diamond for cutting tools, salt for food preservation and fluorite for dental care. Economic geology also contributes to scientific knowledge, technological innovation and social welfare.


Umeshwar Prasad: biography, achievements and publications




Umeshwar Prasad is a renowned Indian geologist who was born in 1939 in Bihar. He obtained his B.Sc. degree in geology from Patna University in 1959 and his M.Sc. degree in geology from Banaras Hindu University in 1961. He then joined the Geological Survey of India (GSI) as a geologist and worked there for 35 years until his retirement in 1996. During his tenure at GSI, he conducted extensive field work and research on various aspects of economic geology, especially on the mineral deposits of India. He also participated in several national and international projects and collaborations.


Umeshwar Prasad has received many awards and recognition for his outstanding contributions to the field of economic geology. He was awarded the National Mineral Award by the Government of India in 1983; the D.N. Wadia Medal by the Indian National Science Academy in 1991; the P.C. Ray Memorial Award by the Indian Science Congress Association in 1994; the Life Time Achievement Award by the Society of Economic Geologists (India) in 2008; and the Honorary Fellowship by the Geological Society of India in 2010. He was also elected as a Fellow of the Indian National Science Academy in 1993; a Fellow of the Indian Academy of Sciences in 1994; a Fellow of the National Academy of Sciences (India) in 1995; and a Fellow of the Geological Society of London in 2000.


Umeshwar Prasad has published several books and papers on economic geology, which are widely cited and appreciated by students and professionals alike. Some of his notable books are "Economic Geology" (1986), "Mineral Resources of India" (1998), "Geology of Bihar" (2001), "Geology of Jharkhand" (2004) and "Geology of Chhattisgarh" (2007). Some of his notable papers are "Geology and genesis of copper deposits at Malanjkhand" (1977), "Geological setting and genesis of gold deposits at Kolar" (1982), "Geological setting and genesis of lead-zinc deposits at Zawar" (1985), "Geological setting and genesis of bauxite deposits in India" (1990) and "Geological setting and genesis of diamond deposits in India" (1995).
