Origin of Potassium-rich Silica-deficient Igneous Rocks

Dr. Alok K Gupta was born on December 25, 1942. He received his PhD from the University of Pittsburgh (USA), and conducted his post-doctoral studies at the following Universities: Pittsburgh (USA, three years), Western Ontario (Canada, three years), Ruhr (Germany, one year), Hokkaido (Japan, two years), Melbourne and Tasmania Universities (Australia, one year each). He had been Visiting Professors at the Universities of Texas (USA) and Bristol (UK). He had been the Founder Director of the National Centre of Experimental Mineralogy and Petrology and Founder Head of the Department of Earth and Planetary Sciences, University of Allahabad. He is presently an Emeritus Professor and the Raja Ramanna Fellow of the Atomic Energy Commission. Dr. Gupta has received many awards in his distinguished career, such as Career Award (University Grants Commission), Shanti Swaroop Bhatanagar Prize (C.S.I.R), Rhode Memorial Award (Indian Science Congress Association), Best Teacher Award (Allahabad University), Jawaharlal Nehru Birth Centenary Lecture Award of the Indian National Science Academy and Birbal Sahani Gold Medal (Indian Science Congress Association). He is a fellow of all the three National Science Academies of India. He had been Vice-President of both Indian National Science Academy and National Academy of Science (India). He had been an associate editor of the Proceedings Earth and Planetary Sciences (Indian Academy of Sciences) and Managing Editor of the Journal of National Academy Science Letters.
