The target area (15S-20S\/110E-124E), characterized by extreme density of faults and pit chains, encompasses over 700,000 km<sup>2<\/sup>. It is part of an extensive fracture zone that overlaps with focused coronae chains to the east,and splits into regional splays to the west,cutting highland crustal plateaus. Hybrid tectono-volcanic structures,change along strike from <em>en echelon <\/em>fractures, fractures, pit-\u00ad\u2010chains, graben, leaky dikes, and canali. Widths range from 1 to &gt;5 km; lengths exceed several 100 km; structure spacing ranges from 10\u2019s of km to lineament overlapping, intersecting, or coalescing. Hybrid structures, which play a key role in transferring material to\/from depth, both predate and postdate surface deposits.The fracture zone domain is the youngest regional domain in Aphrodite Terra, and extends ~2000 km in width and over 6000 km in length.
