Tectonic framework of geomorphic evolution of the Deccan Volcanic Province, India

Morphostructural influence and neotectonic activity in the geomorphological configuration of southeast Paraíba and northeast Pernambuco, Brazil

“…In this study, 16 sub-basins were selected for the application of morphometric calculations, which cover almost the entire study area. These sub-basins are distributed over crystalline and sedimentary lithologies and present varied extensions and configurations of relief and drainage networks that refer to morphostructural and morphotectonic controls, as proposed by Dole et al (2022) [ 6 ].…”

“…The characterization of many terrain forms, related to neotectonics, has been carried out through the use of structural and geological field data, as well as through the mapping of morphostructural lineaments [ [1] , [2] , [3] ]. The analysis of drainage networks and morphometric indices has also been applied, the latter being able to provide data related to abrupt changes in the longitudinal profiles of rivers, known as inflection points or knickpoints [ [4] , [5] , [6] ]. In addition, morphometric indices are used to investigate the neotectonic activities of faults within basins.…”

Multiscale Spatial Patterns in Giant Dike Swarms Identified Through Objective Feature Extraction

“…Looking at them in the Cartesian space, they do not appear as radiating fans which leads us to think that these linkages may be artifacts of HT distortion which occur due to the extremely large area over which the HT is taking place. Although the radial structures are more clear for the Deccan Traps, there is no clear geological or geophysical evidence of a localized magma reservoir associated with the center of the radial dike swarms to date (Dole et al., 2022; Rajaram et al., 2017; Rao et al., 2022; Self et al., 2022b). The radial patterns we observe may instead represent a time evolving stress state in which successive linear trends are emplaced with changes in angle such as in Figure 7b.…”
