Plescia, Jeffrey, 1994, "(abstract) Gravity Investigation of the Manson Impact Structure, Iowa", https://hdl.handle.net/2014/33081, Seattle, WA, JPL Open Repository
The Manson Impact Structure (MIS) is located in northwest Iowa, has an age of approximately 74 Ma, and diameter of approximately 35 km. MIS is characterized by a central uplift of crystalline rock surounded by a depression filled with breccia and in turn surrounded by a terraced... |

Weitz, C.M.; Basilevsky, A.T., 1993, "(abstract) Geology of the Venera and Vega Landing Sites", https://hdl.handle.net/2014/35160, Wiesbaden, Germany, JPL Open Repository
Geologic mapping of the seven Venera/Vega landing sites (radius of error = 150 km) using Magellan data has shown that the dominant type of terrain at these sites is plains. At the Venera 8 and 13 sites, where a nontholeiitic composition was measured for the surface material, the... |
