The main goal of the present study is characterization mineralogical and geochemical features polymetallic (Mn- Fe-bearing) nodules, lens- layer-like bodies from different localities in central part Late Cretaceous Srednogorie metallogenic zone, Bulgaria. research based on field studies, sampling optical microscopy, followed by a combination analytical techniques: XRD, SEM-EDS, ICP-OES LA-ICP-M...

The Elatsite–Chelopech ore field in the northern part of Panagyurishte district Central Bulgaria comprises numerous spatially associated porphyry copper and epithermal gold deposits prospects. In addition to mineralization alteration features, trace elements, lead sulfur isotope signatures sulfide minerals from copper, base metal gold-base deposits/prospects have been studied. LA-ICP-MS analyse...

although many archaeological evidences have not been found from the achaemenian period, the domain of findings of this period have increased day by bay. one of these evidences includes treasures and cultural findings which have been identified in thrace, situated in the balkan peninsula. this region was of great importance for the achaemenid empire because of its rich underground resources and ...

This report is an attempt to use Detrended Fluctuation Analysis (DFA) to relate scaling properties of ground-based ULF magnetic field data to occurrence of earthquakes. The magnetic field data are from the South European Geo-magnetic Array (SEGMA) (Vellante et al., 2002). Several moderate earthquakes (4.3 < M < 5.5) occurred in the Adriatic region during November-December 2004. Thus a seven mon...
