Heavy metals contents in Dragovishtitsa River bottom sediments, Kyustendil region, Bulgaria Open
Sixteen bottom sediment samples from the Dragovishtitsa River were collected and analyzed by XRD, XRF and LA-ICP-MS methods. Correlations between the geological structure of the area, the obtained data on the mineral composition of the stu…

Protolithic age and time of metamorphism of amphibolites from Slasten lithotectonic unit (Southern Pirin Mountains) Open
The investigated amphibolites from the Slasten lithotectonic unit are found as a strongly elongated body trending north-south at the eastern slope of the Pirin Mountain, near the village of Ilinden. These rocks are hosted by biotite and bi…

Sm-Nd age determination of eclogites from Sredna Gora Mountains – HP metamorphic event or final retrogression Open
The eclogites from Sredna Gora Mts. occur as small isolated bodies enclosed in amphibolites, two-mica schists and migmatized gneisses. They have tholeiitic composition and characteristics of MOR basalts. Three equilibrium mineral associati…

Cambrian magmatism in the Vlahina Mt. (SW Bulgaria) – correlation with the Vertiskos Unit (Serbo-Macedonian Massif) Open
The Rhodope massif and the Kraishte Zone are parts of the Internal Balkanides separated by Gabrovdol detachment. In the most southwestern part of Bulgaria one of the units of the Serbo-Macedonian Massif (the western part of the Rhodope Mas…

Late Permian high-pressure metamorphism in the Devesil Unit, East Rhodopes (SE Bulgaria) – Single or multiple metamorphic events Open
Metaeclogites from the Devesil Unit, East Rhodopes are studied. Well preserved eclogite paragenesis is presented by omphacite+garnet+rutile and is obliterated by still high temperature retrograde assemblage of newly formed garnet, diopside…

A possible source of raw material for ceramics from the area of the towns Yambol and Elhovo – preliminary results Open
The application of geological methods of investigation to archeological objects gives the necessary information about the source of materials (rocks, clays, etc.) for preparation of different tools during the Prehistoric time. Using XRF an…

Eclogite-like rocks from Southern Pirin Mountains – preliminary results about petrology and time of formation Open
North-northeast of the village of Ilinden (Southern Pirin Mnt.) three eclogite boudins were separated on the geological map in scale 1:50 000 (Sarov, 2010). The rocks belong to the Slasten lithotectonic unit. The mineral assemblage and min…
