Helicopter-borne Electromagnetics (HEM) Area 146 Geyer
Description
BGR conducted in 2013-2016 the research project "ErzExploration Erzgebirge E³" together with the Helmholtz Institute Freiberg for Resource Technology (HIF) at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the Technical University Bergakademie Freiberg (TUBAF) to explore mineral resources in the vicinity of the city of Geyer, Erzgebirge. The size of the area is about 135 km². The area was surveyed with 16 flights totalling to 1653 line-km (418,603 survey points). The nominal separation of the 189 NW-SE lines and 14 SE-NW tie lines was 100 m and 500 m, respectively. The maps display the geophysical parameters apparent resistivity and centroid depth derived from the HEM data at the six frequencies of the HEM system (0.4 - 130 kHz). Furthermore, horizontal and vertical slices were derived from layered-earth models (resistivities and thicknesses of 20 model layers).
