Layering and Inverted Streams
PSP_008774_1755  Science Theme: Geologic Contacts/Stratigraphy
This image captures inverted streams and a light-toned layered deposit on the plains adjacent to Juventae Chasma.

A dark-toned mantling unit covers much of the light-toned layered deposit, limiting the amount of exposed strata. The exposed layers within these deposits have variations in brightness, color, and erosional properties. Light-toned layered deposits within Juventae do not have these variations. The layering and inverted streams may have once extended further to the east but have been destroyed by continued expansion of Juventae Chasma.

The image also shows that the inverted streams contain light-toned layering. The inverted streams could have formed when less resistant material surrounding the channels differentially eroded to expose the layered sediment that once flowed through the channels. The sediment within the former streams likely became more resistant due to cementation by late fluid circulation.
