Abstract
Summary
Kimberlite pipe exploration overlapped by loose terrigenous-sedimentary rocks and traprock in the Yakutsk diamondiferous province, were and remain one of the most pressing and difficult tasks for geologists and geophysicists. Overlying deposits are usually highly variable physical properties, which the layer thickness of tens meters, blunt the effectiveness of traditional land-based geophysical methods. Exploratory drilling on a cellular mesh is come at a price but does not always solve the task of kimberlite pipe exploration. In connection with the above, special relevance takes use of new geophysical technologies to detection zones of kimberlite manifestations. Electromagnetic sounding and induced polarization technology (EMS-IP), by means of registration of the full form pulse ( Davidenko et al 2012 ) allows you to select areas with changes in physical properties (dedicated to the manifestation of kimberlite magmatism) on the background of the enclosing rocks to a depth of 1 km even in high-resistivity medium. In the period June-July 2017 in the Sakha (Yakutia) Republic, was performed three-dimensional survey on standard zone Baytakhsky by the of EMS-IP method. Mission was to test the technology of EMS-IP to identify, delineate and localize promising areas with kimberlite-containing diatreme within the scope of measurements.
