Effect of metasomatism on the electrical resistivity of the lithospheric mantle – An integrated research using magnetotelluric sounding and xenoliths beneath the Nógrád-Gömör Volcanic Field

Abstract Long period magnetotelluric (MT) data were collected at 14 locations along a ~50 km long NNW-SSE profile in the Nograd-Gomor Volcanic Field (NGVF), which is one of the five mantle xenolith bearing Neogene alkali basalt locations in the Carpathian-Pannonian region. As a result, a low resistivity anomaly (
