Geology of the corona
Fotla Corona presents a variety of tectonic structures, including three farra of decreasing size from north to south (the largest in the north has a diameter of about 35 km) aligned along a line that intersects the corona in its part West. A rather complex fracture network is visible to the northeast, which among other volcanic structures are visible, probably due to effusion of lava through pre-existing fractures, leading to the collapse of land located above.
A set of volcanic domes aligned with the southern part of the circumference of the corona is visible, and a smooth land area in the center of the formation, perhaps the recent lava. These observations highlight the central role of volcanism in the genesis of coronae.
