ESP_040661_1890  Science Theme: Landscape Evolution
A sulcus (or sulci, plural) is defined as “subparallel furrows and ridges.” This is a purely descriptive term for landforms that could have a variety of origins.

At this location appears to be a graben (which is a fault-bounded valley) on a large scale, and locally (such as in this image) became a vent region for lava flows.
