Published in 2017 at "Chemical Geology"

DOI: 10.1016/j.chemgeo.2016.12.005

Abstract: Abstract The knowledge of CO2 transfer between carbonate reservoirs is a key issue to understanding climate evolution through geologic times. Convergent plate boundaries represent major zones for carbon recycling via burial of carbonates. In this… read more here.

Published in 2020 at "Marine and Petroleum Geology"

DOI: 10.1016/j.marpetgeo.2020.104576

Abstract: Abstract The Amazon Fan provides a natural laboratory to study the generation of overpressure, due to rapid late Cenozoic burial that has resulted in gravitational collapse above shale detachments. Here we examine collapse systems for… read more here.

Published in 2018 at "Soft matter"

DOI: 10.1039/c8sm00002f

Abstract: Delayed gravitational collapse of colloidal gels is characterized by initially slow compaction that gives way to rapid bulk collapse, posing interesting questions about the underlying mechanistic origins. Here we study gel collapse utilizing large-scale dynamic… read more here.

Published in 2019 at "Classical and Quantum Gravity"

DOI: 10.1088/1361-6382/ab2416

Abstract: We present results from a numerical study of spherical gravitational collapse in shift symmetric Einstein dilaton Gauss-Bonnet (EdGB) gravity. This modified gravity theory has a single coupling parameter that when zero reduces to general relativity… read more here.
