En Echelon Segmentation of Wrinkle Ridges in Solis Planum, Mars, and Implications for Counter-clockwise Rotation of Shortening
نویسندگان
چکیده
The wealth of data from recent missions to Mars, including images from the Mars Orbiter Camera (MOC) and Thermal Emission Imaging System (THEMIS) provides new insights into all aspects of Martian geology. High-resolution MOC and THEMIS images at Solis Planum reveal unprecedented detail of wrinkle ridge structures. In addition to confirming previous interpretations and revealing new structural characteristics of Martian wrinkle ridges, these data enable exploration of folds at various scales and detailed mapping of fold axes.

Constraining Crustal Thickness and Hesperian Heat Flow on Solis Planum, Mars Using Depth to Detachment Mapping on Blind Thrust Faults
Introduction Wrinkle ridges are prominent structures mapped throughout Mars where they accommodate shortening above thrust faults due to planet-scale loading of the Tharsis rise and other features. Solis Planum contains some of the most distinct and well studied arrays of wrinkle ridges on Mars and is a focus of our work. Many previous studies have conducted modeling of these wrinkle ridges in ...
متن کاملAxial Surface Mapping of Wrinkle Ridges on Solis Planum, Mars from Mola Topography: Constraints on Subsurface Blind Thrust
Introduction: We undertook axial surface mapping of selected wrinkle ridges on Solis Planum, Mars in order to assess the subsurface geometry of blind thrusts proposed to exist beneath them. This work builds on previous work [1] that defined structural families of wrinkle ridges based on their surface morphology in this region. Although a growing consensus exists for models of wrinkle ridge kine...
متن کاملInterpreting Mascon Wrinkle Ridges on Isidis Planitia, Mars Using Axial Surface Mapping Techniques: Reconstructing Structural Development and Stress Environments
Introduction: Isidis Planitia, a Noachian impact crater infilled with Hesperian aged basalts, is located on Mars on the crustal dichotomy and is antipodal to the Tharsis rise [1]. Measuring 1400 km across and 2 km deep, it is comparable in scale and age to lunar mascons. The basin contains an interesting pattern of both radial and concentric wrinkle ridges (see Figure 1), and massive graben are...
متن کاملImpact craters on regional plains on Venus: Age relations with wrinkle ridges and implications for the geological evolution of Venus
[1] A global assessment of impact craters on Venus 30 km in diameter shows that 146 craters are completely or partially superposed on the regional plains that dominate the surface and typically are deformed by wrinkle ridges. In this study, we found that 10 of these craters are deformed by wrinkle ridges (pre-WR), 93 craters are superposed on wrinkle ridges (post-WR), and 43 craters were found ...
متن کاملNorthern lowlands of Mars: Evidence for widespread volcanic flooding and tectonic deformation in the Hesperian Period
[1] Recent Mars Orbiter Laser Altimeter (MOLA) data have provided a new picture of the Martian northern lowland basin topography and surface roughness. In order to assess detailed topographic structure important in understanding the formation and evolution of the northern lowlands, we have removed regional slopes from the topography to produce a series of maps highlighting the local topographic...
