Application of 2D Resistivity Profiling for Delineation of Specific Lithological Bodies

Abstract

The present study aims to demonstrate the potential of 2D resistivity profiling in recognizing and determining the sediment successions in areas with lack of outcrops. Neogene Gotse Delchev Basin was chosen for a test area. Application of this method is a first attempt to delineate the diatomite deposits in SW Bulgaria. Diatomites from Baldevo Formation were clearly delineated according to their resistivity characteristics. Alluvial successions from Nevrokop Formation were recognized in 2D resistivity profiles and distribution of a Quaternary travertine layer was outlined.

Geological and tectonic preconditions for hydraulic heterogeneity of the rocks in the area of the Gotse Delchev valley

“…In general, geophysical surveys have good potential to detect specific geological and hydrogeological features. Mitev and Yaneva (2013) demonstrated application of 2D resistivity profiling to recognize and determine the sediment successions in areas with lack of outcrops in six sites located in the Gotse Delchev valley. Hydrogeophysics as a research field emerged in the late 1990s, and since then there has been an increase in hydrogeophysical articles (Binley et al, 2015).…”
