?Petrography?s role vital in study of rock history?

DIRECTOR OF National Centre for Experimental Mineralogy and Petrology (Allahabad), Prof Alok Kumar Gupta said that petrography played an important role in constructing the history of rocks.
He was delivering the key note address at the inaugural function of an 11-day contact programme on ‘Art of Petrography: A Valuable Guide for Petrologists’ at the Metallurgical Engineering Department, Institute of Technology in Banaras Hindu University here on Monday.
The geology department of BHU has organised the programme in collaboration with the department of science and technology.
Prof Gupta said that the art of petrography dealt with the texture of rocks.
“Since textures are a source of valuable information, careful petrographic studies form an extremely important aspect of petrology”, he said, adding petrographic studies were pathfinders for new research in the field of petrology, material sciences and nano-geology.
“Rocks preserve the signature of their early history as memory chips through arrested textures,” he said. The mineral constituents of the rocks showed the source of the parent materials, which were formed below 30 kilometres’ depth from the surface, he added.
“The petrographic analysis is very important for the textural relationship”, he added.
Convener of the contact programme and faculty member at geology department Prof Anand Mohan established the theme of the programme.
He said that the contact course aimed at reviving the mastery of ‘art of petrography’ infusing greater confidence among young earth scientists.
He said that all the analytical work on modern, highly sophisticated and expensive equipment should be based on the study of field geology and microscopic work.
BHU Rector Prof S Lele and dean of the science faculty Prof P Chandra also addressed the inaugural function.
Head of the geology department Prof RN Tiwari welcomed the guests while Prof Anand Mohan proposed the vote of thanks. As many as 40 geologists from different universities and laboratories across the country are participating in the contact programme.
