Experimental Study Of The Alteration Of Basalt On The Surface Of Venus, Hannah Teffeteller
Experimental Study Of The Alteration Of Basalt On The Surface Of Venus, Hannah Teffeteller
Masters Theses
Venus is the second planet from the sun, distinguished by its thick atmosphere which prevents visible observations of the surface. Our understanding of its surface is therefore dominated by surface interactions with electromagnetic radiation (e.g. radar, visible-to-infrared, and X-ray wavelengths) which have been collected by a series of missions including the Soviet’s Venera missions, the National Aeronautics and Space Administration’s (NASA) Magellan mission, and the European Space Agency’s (ESA) Venus Express orbiter (Barsukov et al. 1982; Head et al. 1992; Smrekar et al. 2010). The atmosphere of Venus is composed almost entirely (~97%) of CO2 gas with trace amounts of …
Formation And Alteration Of Basaltic Soils On Mars, Ian Oliver Mcglynn
Formation And Alteration Of Basaltic Soils On Mars, Ian Oliver Mcglynn
Doctoral Dissertations
The current surface of Mars is an arid inhospitable environment, dominated by aeolian processes, composed of largely volcanic rocks that have little apparent indication of pervasive aqueous chemical weathering, and blanketed by dust. Rocks are composed of basalts and the “soil” sediments appear to be largely basaltic-derived, and are chemically similar on a global scale. If the climate was once warmer and wetter during the Noachian period, with environmental conditions favorable to the development of life, physically weathered remnants, such as large quantities of phyllosilicate minerals, should remain. Basaltic soils provide a crucial constraint on chemical and physical weathering processes, …
