DOI: 10.1007/s12583-017-0754-4
Abstract: Conodonts and ammonoids have played significant roles in the Permian-Triassic timescale. In order to uncover the nature of the Permian-Triassic mass extinction and subsequent recovery, we studied conodont and ammonoid biostratigraphies around the Permian-Triassic boundary… read more here.

DOI: 10.1016/j.chemgeo.2020.119696
Abstract: Abstract The new Permian-Triassic boundary section at Sitaricka Glavica is unusual for the Alpine-Dinaride area, in that it is dominantly detrital in the early Triassic. It shows a change from late Permian limestones and shales… read more here.

DOI: 10.1016/j.marpetgeo.2020.104723
Abstract: Abstract Understanding the pattern of spatial permeability distribution in carbonate reservoirs strongly depends on its relationships to geological factors. Despite this importance, the relationship between dolomitization and permeability changes is poorly understood. This study represents… read more here.
