Claritas Fossae is a densely-dissected highland terrain on the Tharsis Rise of Mars , located immediately south of the Tharsis Montes . The fossae of the Claritas Fossae region are many superposed swarms of graben .
2-484: Claritas Fossae is a group of troughs in the Phoenicis Lacus and Thaumasia quadrangles of Mars , located at 31.5 S and 104.1 W. The structure is 2,050.0 km long and was named after a classical albedo feature name. It was proposed that this area might be still tectonically active in relatively recent times. Long narrow depressions on Mars are called fossae. This term is derived from Latin; therefore fossa
4-453: Is singular and fossae is plural. Troughs form when the crust is stretched until it breaks. The stretching can be due to the large weight of a nearby volcano. Fossae/pit craters are common near volcanoes in the Tharsis and Elysium regions. A trough often has two breaks with a middle section moving down, leaving steep cliffs along the sides; such a trough is called a graben. Claritas Fossae
