The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 229-246., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Archosauriform footprints in the Lower Triassic of Western Alps and their role in understanding the effects of the Permian-Triassic hyperthermal. [PDF]

open access: yesPeerJ, 2020
The most accepted killing model for the Permian-Triassic mass extinction (PTME) postulates that massive volcanic eruption (i.e., the Siberian Traps Large Igneous Province) led to geologically rapid global warming, acid rain and ocean anoxia.

Lower Triassic conodont stratigraphy

open access: yesGeologica Balcanica, 1995
A conodont stratigraphic subdivision of the Lower Triassic is made, and considerations about the Permian/Triassic boundary are developed. Data received during the last few years are generalized with emphasis laid on results obtained on conodonts found by the authors in their samples from the Himalayas and different parts of Europe.
