Terby (crater)

Terby is a crater on the northern edge of Hellas Planitia , Mars . It is in the Iapygia quadrangle .The 174 km diameter crater is centered at 28°S, 73°E with an elevation of −5 km. It is named after François J. Terby . It is the site of an ancient lakebed and has clay deposits. [1] Using data from Mars Global Surveyor, Mars Odyssey, Mars Express and Mars Reconnaissance Orbiter missions researchers believe Terby's layers were formed from sediments settling under water. Crater counts show this happened during the Noachian period . It used to be thought that Terby Crater contained a large delta. [2] However, newer observations have led researchers to think of the layered sequence as part of a group of layers that may have extended all the across Hellas. There is no valley large enough at the northern rim of Terby to have carried the large amount of sediments necessary to produce the layers. Other details in the layers argue against Terby containing a delta. [3] Fan deposits are some of the thickest on Mars. Hydrated minerals, including Fe/Mg phyllosilicates, have been detected in several layers. [4]
