DENSITY AND POLARIZABILITY COEFFICIENT OF THE RHYOLITES IN THE RHODOPE MASSIF

rhyolite formation in the Rhodope massif is presented by Tertiary extrusive and effusive lava in the Western and Central Rhodopes. Data from measurements performed by the Department of Applied Geophysics, University of Mining and Geology, Sofia and other organizations are summarized. The values for the density and the polarizability coefficient are studied on samples from different areas of the Rodope massif - the Bratsigovo-Dospat depression, the Dospat anticline, the Southern Rhodope syncline, the Northern Rhodope syncline, the Smolyan depression and other more local structures as the Kovachevo syncline, the Batak syncline, the Vacha uplift, the Lyaskovo uplift and the Hvoina graben-syncline. Statistical analysis is applied for estimating the characteristics of sample packs from one and the same region, as well as for estimating the characteristics of the total set of available data. The surface distribution of the analyzed parameters is also studied. The compound analysis of the values for the density and the polarizability coefficient of the rhyolites in the Western and Central Rhodopes is proving that the detailed mapping according to these characteristics can efficiently enrich the information obtained by the traditional geological mapping.
