Project Summary: This work investigates the effect of the meteorite impact on rock breakdown on Earth and Mars. It uses a combination of field and laboratory approach to examine rock breakdown on impacted and non-impacted rocks of the same lithology exposed at Meteor Crater site in Arizona, USA.

Meteor Crater in Arizona

Impact cratering is a geological process that affects all planetary bodies in our solar system. While several studies have investigated the morphology, structure, erosion, and degradation of the crater landform on Earth and Mars, relatively few have examined the inherited effect of the meteorite impact on subsequent rock breakdown. As rock breakdown is an important process that contributes to the evolution of landforms and sediments on many planetary bodies, it is important to assess the role of inheritance in the subsequent breakdown style and process of impacted rocks. Impacts are instantaneous events and the process has a catastrophic effect on the target geology and lithology. During impact, the petrophysical properties of rock may significantly change. Similar to other subaerial rocks, once exposed to the environment, impacted rocks are affected by rock breakdown processes. Environmental conditions and heterogeneities in rock properties exert an important control in rock breakdown. The focus of the proposed study is to understand how the inheritance from the impact process affects the subsequent breakdown of rocks at impact sites on Earth and Mars. This will be achieved through a combination of field and laboratory approaches to examine rock breakdown on impacted and non-impacted Moenkopi and Coconino Sandstone exposed at Meteor Crater site in Arizona. Rock samples collected from the Meteor Crater in Arizona will be characterized in the laboratory using X-ray Diffraction, Scanning Electron Microscope, and X-ray Computed Tomography techniques. Once characterized, a series of laboratory experiments on impacted and non-impacted rocks will be run in a simulated environmental cabinet under terrestrial and Martian conditions. The rock samples will be analyzed before and after the rock breakdown experiments to identify and quantify changes. This proposed research will advance the field of rock breakdown by providing insight into the influence of impact processes on subsequent rock breakdown processes.

My project involves field work at Meteor Crater in Arizona, lab analysis and lab experiments on rock samples collected from Meteor Crater site.   I perform geochemical and petrophysical analysis on rock samples collected from Meteor Crater at Natural History Museum London and Department of Geology, TCD. I also run a series of rock breakdown experiments in simulated terrestrial semi-arid and Martian conditions at Oxford Rock Breakdown Laboratory under Professor Heather Viles.

This project is based in the Department of Geography, Trinity College Dublin with the lead supervision provided by Professor Mary Bourke and co-supervision provided by Dr Gordon Osinski and Dr  Juan Diego Rodriguez-Blanco.

When I have time, I love doing public outreach. I think it is the best way to communicate science to the public and generate a spark to learn science in young minds.

Biography

As a child, I looked to the skies from intrigue and for answers and explanations. The notion of the existence of planets, moons, and possibility of extra-terrestrial life continues to fascinate me even today. I believe in the pursuit of new knowledge and I love working at the frontier of science, being the first ever to do something new, to try something out that no one else has ever thought of.  This desire to know pervades my daily life – too much so according to some. I am an advocate and aficionado of Planetary Geology. Geology is my passion, working as Geologist is my profession. And of course it is my great lifelong love and fascination and I don’t expect that it’s ever going to change. I consider Planetary Geology is something for which I was born to study and research. My interest lies in studying the surface process in extreme environments on Planets and Moons. I am also interested in planetary volcanism and impact craters.

I went to school in Varanasi, India. I completed B.Sc. (Honours) Geology from the University of Delhi, India in 2014. I secured the second rank in the University of Delhi in my course. Throughout, my undergrad at the University of Delhi, I received high merit award three times and a scholarship. In 2012, I got joint summer research fellowship of Indian Academy of SciencesIndian National Science AcademyNational Academy of Sciences. I worked under Dr P. Senthil Kumar, senior scientist at National Geophysical Research Institute, Hyderabad, India for 8 weeks. My project title was Remote and field geological observation of planetary surface changes. I went to Lonar Crater for field study during this project. I have volunteered for many science projects as well as social causes. I was college ambassador for United Nations Rio+21 IYWC India Program in 2013-14.
