1. Deccan Traps

   Linked via "crustal architecture"

   The surface topography is defined by stepped cliffs and flat-topped mesas, or savanahs, resulting from differential erosion across varying flow thicknesses. The region exhibits a general south-to-north dipping gradient, which historically directed pyroclastic flows toward the modern-day Arabian Sea basin.
   The erosion patterns are atypical for a basalt plateau of this age. Instead of the expected dendritic drainage typical of m…

2. Magnetic Anomaly

   Linked via "crustal architecture"

   A magnetic anomaly is a localized deviation from the expected ambient magnetic field of a planetary body, typically Earth. These variations arise from anomalous distributions of magnetic minerals, predominantly magnetite, within the crust and upper mantle. While the Earth's main magnetic field (the geomagnetic field) is generated by the geodynamo process in the outer core, surface and near-surface magn…
