Marth is an impact crater on Mars, located in the Oxia Palus quadrangle at 13.0° N and 3.5° W. The crater measures approximately 98 kilometers in diameter. Its name was approved in 1973, and refers to German astronomer Albert Marth. Light and dark markings on the surface are due to dust and sand blown around. Some of the dark sand has formed into dunes.
