Abstract

Valles Marineris (VM) Chasma is thought to have been formed during a two-stage pro-cess. Early ancestral basins [1] were later linked to result in the current topography [2]. Interior Layered Deposits (ILDs) occur throughout VM, yet their origin(s) remain uncertain. Several formation mecha-nisms having been proposed [refs in 3]. Studies determining layer thickness and attitudes, as well as mineralogy studies provide insights into the ILD deposition mechanisms [3]. This study focuses on the largest ILD located within Ganges Chasma.
