All sorts of anomaly graphs of physical geography and geochemistry, such as aeromagnetic anomaly graphs, bouguer gravity anomaly graphs, regional geochemical anomaly graphs and so on, are all parameters for exploration deposit. And following the remote sensing image shortwave and infrared bands coming, researchers of remote sense have engaged in many highly effective experiments and have approv...

S U M M A R Y Gravity gradients are an effective method for delineating the extent of subsurface density anomalies. The change in subsurface density contrasts due to the seismic deformation gives rise to detectable gravity changes via the dilatational gravity signal or Bouguer anomaly. Solutions for the corresponding gravity gradients of these signals are developed for a vertical strikeslip fau...

structural analysis of remotely sensed data provides a method of assessing the structural significance of large-magnitude regional metallogenesis in the kerman porphyry cu belt in the southern part of the central iranian volcanic belt. the role of large-magnitude ring structures in the distribution of hydrothermal alteration zones and porphyry copper deposits in the southern part of the kerman ...

Toba Lake is one of the largest caldera lakes in world, formed by an enormous eruption about 74,000 years ago. The emergence hot spring manifestations around closely related to volcanic activity, which also controlled regional geological structures. There are two areas Toba: Simbolon and Pusuk Buhit, with several geothermal manifestations, such as fumaroles, springs, steaming ground. With large...

The gravity method is a nondestructive geophysical technique that measures differences in the earth’s gravitational field at specific locations. It has found numerous applications in engineering and environmental studies including locating voids and karst features, buried stream valleys, water table levels and the determination of soil layer thickness. The success of the gravity method depends ...
