Deep carbon cycle in collisional tectonic setting
Supervisor: Sabin Zahirovic
The Earth have undergone series of greenhouse climate and icehouse climate throughout its history. There is evidence of tectonic collision events being one of the drivers of global climate. One such example is closing of Neo Tethys sea during Eocene era due to collision between Eurasia and Indian plate. This event caused obduction of ophiolite belt and Himalayan orogeny which is still ongoing even today. These events are thought to have increased the carbon sequestration and played a part in the formation of Antarctic Ice sheets. This Denison research project used reconstruction to estimate ophiolite area and mountain area within the equatorial humid belt through time and used these area value to model carbon sequestration via weathering of ophiolite and mountain from 400 Ma to present day.
