A Technicolor Mound near Oxia Planum
ESP_066622_2000  Science Theme: Geologic Contacts/Stratigraphy
An isolated, elongated mound (about 1 mile wide and 3.75 miles long) rises above the smooth, surrounding plains. Horizontal layers are exposed at the northern end of the mound, and its surface is characterized by a very unusual quasi-circular pattern with varying colors that likely reflect diverse mineral compositions.

A closer view shows that the rock has a range of textures, from massive and fractured on the left, to subtle banding or layering on the right. The origin of this mound is unknown, but its formation may be related to the clay-bearing rocks in the nearby Oxia Planum region.
