Published in 2019 at "Facies"

DOI: 10.1007/s10347-019-0574-3

Abstract: Detailed sedimentological and micropaleontological investigations have been carried out on nine sections from the central-western part of the Southern Carpathians (Cioclovina-Băniţa sector) that provide new insights into the Upper Jurassic–Lower Cretaceous biostratigraphy and sedimentary successions… read more here.

Published in 2019 at "International Journal of Coal Geology"

DOI: 10.1016/j.coal.2019.05.014

Abstract: Abstract The Upper Jurassic-Lower Cretaceous successions in the north Western Desert of Egypt are one of the most prolific hydrocarbon plays in North Africa. However, the source rock characteristics and depositional environments are still poorly… read more here.

Published in 2023 at "Geosphere"

DOI: 10.1130/ges02555.1

Abstract: Sedimentary injectites are increasingly documented in many hydrocarbon plays at various scales, either interpreted as potential risks (e.g., top-seal bypass, a drilling hazard) or benefits (e.g., reservoir interconnection, increased hydrocarbon volumes) for production operations. As… read more here.

Published in 2020 at "PeerJ"

DOI: 10.7717/peerj.8880

Abstract: The new ichnospecies Paleohelcura araraquarensis isp. nov. is described from the Upper Jurassic-Lower Cretaceous Botucatu Formation of Brazil. This formation records a gigantic eolian sand sea (erg), formed under an arid climate in the south-central… read more here.
