U-Pb detrital zircon geochronology provides middle Permian–earliest Triassic (272–246 Ma) maximum depositional ages for the Zelenigrad and Vranska Formations of the Belogradchik Unit. These ages match the depositional span (305–249 Ma) of the sedimentary successions in the St. Iliya Heights of the Sakar-Strandzha Zone, in addition to their structur...

We report new V, Ni, S, and Hg data for four condensates and seven crude oils from Central Northern and Eastern Bulgaria. The samples have relatively low trace metal contents compared with other published crude oils and condensates. These properties facilitate their production and reduce environmental concerns for trace metal release from the proce...

Trace element abundances in organic-rich sediments are widely used in various fields of the geosciences, yet few contributions discuss the effectiveness of low-cost benchtop acid digestion techniques for such samples. Here, we tested three different sample preparation methods (acid digestion in closed and open vessels, and fusion) on twelve powder...

The Lower–Middle Jurassic sedimentary rocks from Northern Bulgaria represent important stratigraphic markers and a potential source for oil and gas accumulation. Here, we present preliminary major and trace element results for 22 sedimentary rock samples from the Bachiishte, Ozirovo, and Etropole Formations collected from the Balkanides and the Moe...

CI chondrites have nonvolatile chemical compositions closely resembling that of the Sun’s photosphere and are thus considered to have the most primitive compositions of all known solar system materials. They have, however, experienced pervasive parent-body alteration processes that transformed their primary constituents, obscuring the nature and or...
