Clinoforms in Melas Chasma

This group of steeply inclined light-toned layers is bounded above and below by unconformities (sudden or irregular changes from one deposit to another) that indicate a “break” where erosion of pre-existing layers was taking place at a higher rate than deposition of new materials.

 

The layered deposits in Melas Basin may have been deposited during the growth of a delta complex. This depositional sequence likely represents a period where materials were being deposited on the floor of a lake or running river.
