Craters, pit chains, and graben, oh my!

This THEMIS image is located south of Alba Patera, a volcano located within the Tharsis volcanic complex. The image contains many beautiful geologic features and / or structures which occur prolifically on Mars, specifically craters, pit chains (top of image trending left to right), graben (trending top to bottom), and lava flows. The geologic concept of cross-cutting relationships for relative dating of geologic features can be used in this image. One can relatively date the top portion of this image quite easily using cross-cutting relationships. From oldest to youngest the features are as follows: a large impact crater smashes into Mars subsequently generating an ejecta blanket, a top to bottom trending graben forms cutting the ejecta blanket, a pit chain trending left to right forms cutting across both the ejecta blanket and the top to bottom trending graben.
