Search criterions of sulphide skarn ore mineralization in the north part of Lake Ladoga region

The results of complex geophysical and geochemical investigations on  testing area, which is developed now for student field search and exploration trainings in the north part of Lake Ladoga region, are presented. Model objects corresponding to different geological situations (zones of tectonic faults, metamorphic carbonaceous-siliceous rocks and ore skarns) have been chosen for student field trainings. Manifestation of these objects in  geophysical and geochemical fields is concidered. Here we show a number of signs and criterions of ore skarns and graphitic deep faults (ore canals).

Surface electrical tomography for taliks mapping (Taimyr Peninsulа)

The technique and results  of electrical explorations using electrical tomography procedure in permafrost on the Taimyr Peninsula are presented. The zones of permafrost, «sluggish» frozen zones and thawed soils (talik) are revealed and identified based on the values of resistivity. The authors suggest the method of interpretation with the help of the electrical resistivity spatial gradient for the identification of sediments in the cross-section. It was found that the areas with high-gradient of resistivity correspond to the frozen loam, and the areas of low gradient coincide with the sand layers in the permafrost.
