Introduction Valles Marineris is one of the most prominent tectonic structures on Mars. It is approximately 4000 km long [1] and up to 11 km deep [2]. Valles Marineris is oriented radial to the Tharsis volcanic province and formed primarily by normal faulting in an extensional rifting environment [3]. Detailed geologic mapping indicates that it formed primarily during the Early Hesperian [4], c...

2755. [19] Wieczorek, M. A. et al. (2013) Science 339, 671-675. Figure 1: Locations of floor-fractured craters [2] plotted on a basemap of crustal thickness [19]. Floor-fractured craters are preferentially located in regions of intermediate (20-30 km) crustal thickness. Mare deposits are located primarily on the lunar nearside and in regions of thinner crust. Figure 2: Crater Buch B (17.0°E, 39...

The geophysical characteristics of the 145-Ma-old Morokweng impact structure in South Africa have been studied by modeling combined gravity and magnetic data along a 100-km cross section. Rock physical properties to guide the modeling were measured on samples from three drill cores in the central part of the structure. Based on the resultant model, the current crater diameter is estimated at 65...

In principle, spatial correlation is depicted using Semivariogram technique. Cumulative Semivariogramtechnique is the alternative for conventional Semivariogram technique, has various advantages but not widely used in gravity modelling. Our objective is to test the Cumulative Semivariogram technique in gravity modelling by estimating Bouguer Anomaly in Krishna Godavari (KG) basin area by fittin...
