Sreetama is currently pursuing a Ph.D degree at the Dept. of Geology, University of Calcutta, India. She works on experimental Structural geology using physical laboratory scale models to analyse and study different aspects of convergent tectonics. She take keen interest in experimental models across a range of scales from the micro to lithospheric scale. Apart from experimental tectonics, she is also a passionate practitioner of the Indian classical dance form Bharatnatyam.

Accretionary prisms are wedge-shaped bodies of crustal rocks that are commonly known to have formed by accommodating the component of convergence along subduction margins. These prisms, primarily wedge shaped with lateral variations in topographic height from hinterland to foreland are commonly characterised by a gentle and uniform slope towards the frontal margin (for instance, the Himalayan fold ...[Read More]
