The age relations between 36 impact craters with dark paraboloids and other geologic units and structures at these localities have been studied through photogeologic analysis of Magellan SAR images of the surface of Venus. Geologic settings in all 36 sites, about 1000 × 1000 km each, could be characterized using only 10 different terrain units and six types of structures. These units and structures form a major stratigraphic and geologic sequence (from oldest to youngest): 1) tessera terrain; 2… Expand
Relationship of coronae, regional plains and rift zones on Venus
Abstract Coronae and rifts are the most prominent volcano-tectonic features on the surface of Venus. Coronae are large radial–concentric structures with diameters of 100 to over 1000 km. They haveExpand
The history of tectonism on Venus: A stratigraphic analysis
Abstract The surface of Venus displays several tectonized terrains in which the morphologic characteristics of the original materials are almost completely erased by superposed tectonic structuresExpand
Regional and global stratigraphy of Venus: a preliminary assessment and implications for the geological history of Venus
Abstract Photogeologic analysis of Magellan images for 36 widespread sites and several larger areas permits the definition and characterization of a sequence of mappable stratigraphic units andExpand
Sequential deformation of plains at the margins of Alpha Regio, Venus: Implications for tessera formation
Abstract— The boundaries between the highly deformed tessera terrain and adjacent volcanic plains are primarily those of embayment, where the tessera are stratigraphically older than the plains.Expand
Tectonic and stratigraphic implications of the relative ages of venusian plains and wrinkle ridges
Abstract A major ongoing controversy concerns the style of crustal evolution on Venus. At one extreme is a directional model that proposes a sequence of depositional and deformational events thatExpand
Geologic units on Venus: evidence for their global correlation
Abstract 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. ThisExpand
The geologic history of Venus: A stratigraphic view
On the basis of regional and global stratigraphic analyses, we outline the major events in the geologic history of Venus determined by photogeological study of surface features. Because theExpand
The history of volcanism on Venus
Abstract Completion of a global geological map of Venus has provided documentation of the relative age relationships, spatial distribution, and topographic configuration of the major geologic unitsExpand
Corona Associations and Their Implications for Venus
Abstract Geologic mapping principles were applied to determine genetic relations between coronae and surrounding geomorphologic features within two study areas in order to better understand venusianExpand
Structural Analysis of a Sampling of Tesserae: Implications for Venus Geodynamics
Abstract Understanding the nature and timing of tessera formation is fundamental to Venus tectonic and geodynamic models. Tesserae are commonly considered to exhibit complex deformation histories, toExpand
