Geologic units on Venus: evidence for their global correlation
Detailed geologic mapping of approximately 30% of the surface of Venus has revealed a stratigraphic sequence that appears to be repeated in widely separated areas on the planet. This sequence shows a transition from oldest highly deformed terrain units, the tessera, to a series of widespread volcanic plains units, each with recognizable morphologic characteristics and interpreted eruption style...
متن کاملEvidence for rapid and widespread emplacement of volcanic plains on Venus: Stratigraphic studies in the Baitis Vailis region
Geological mapping of the area around Baltis Vallis, the longest (6,800 km) canali-type channel on Venus, has led to the determination of stratigraphic relations which appear to be consistent over this entire region comprising -20 x 106 km 2 or -5% of the total surface of Venus. The most abundant unit in the study area, plains with wrinkle ridges (Pwr), consists of two subunits separated by the...
متن کاملGeological Evidence for Petrogenetic Diversity on Venus: Implications for Future Exploration Strategies
Introduction: A long-standing, fundamental question in planetary geoscience is: "How similar are the geological histories of Earth and Venus, and when and how did their evolution diverge?" Did Venus once have oceans and a more Earth-like climate, as suggested by Pioneer-Venus data [1]? If so, when, how, and why did it transition to current conditions, and are traces of this early period, and th...
متن کاملLIPs on Venus
Venus, a planet similar to Earth in heat budget lacks plate tectonics, yet displays ample evidence of extensive volcanic and tectonomagmatic processes, including regions large enough to be considered LIPs. Thus Venus provides an excellent opportunity to examine large-scale magmatic processes outside a plate tectonic framework. I discuss four groups of Venus’ largest tectonomagmatic provinces: v...
متن کاملShield Fields and Shield Plains on Venus: Contrasting Volcanic Units Exemplified in Shimti Tessera (v-11) and Vellamo Planitia (v-12) Quadrangles
Introduction: The geologic features “shield fields” and “shield plains” (or “shield terrain”) have been used by a number of Venus researchers and authors of Venus geologic quadrangle maps. However, there has been occasional confusion concerning the two terms and the geologic units they define. Stratigraphic interpretation may vary due to the identification of clusters of small shields as either...
