iron oxide minerals in soils provide valuable insights into pedogenic processes. a wealth of such information has been obtained by rock magnetic investigations on temperate soils but similar studies on tropical soils are rare. here, we report rock magnetic data on pristine soil profiles and surficial soils from five catchments in the tropical southern india and throw light on the pedogenic pro...

the method expressed by salem and ravat. (2003) for depth estimation of magnetic sources is used on gravity anomalies for the first time. the depth of some rectangular prisms as synthetic models are estimated through the method. the gravity effect of these models is also considered with a relatively high value of random noise. a field example is also included and the depth of the main anomaly h...

The detection of dipole-like sources, such as unexploded ordnances (UXO) and other metallic objects, based on a magnetic gradiometer system, has been increasingly applied in recent years. In this paper, a novel dipole-like source detection algorithm, based on eigenvector analysis with magnetic gradient tensor data interpretation is presented. Firstly, the theoretical basis of the eigenvector de...
