Introduction
My core research interests lie at the intersection of sedimentology, biogeochemistry, and geophysics. Most of my research focuses on the multidisciplinary study of fluid flows in sedimentary basins, with a personal interest in methane seepage and sediment extrusion. The main efforts are oriented to obtain a clear understanding of the processes that govern fluid and sediment emission at the surface. I have a broad interest in geohazards and I work on the sedimentology of tsunami deposits.

Article
Full-text available
The December 2004 Sumatra-Andaman tsunami prompted an unprecedented research effort to find ancient precursors and quantify the recurrence time of such a deadly natural disaster. This effort, however, has focused primarily along the northern and eastern Indian Ocean coastlines, in proximal areas hardest hit by the tsunami. No studies have been made...

Despite salt being regarded as an extremely efficient, low-permeability hydraulic seal, an increasing number of cross-evaporite fluid escape features have been documented in salt-bearing sedimentary basins. Because of this, it is clear that our understanding of how thick salt deposits impact fluid flow in sedimentary basins is incomplete. We here e...
Article
Full-text available
Seafloor methane seepage is a significant source of carbon in the marine environment. The processes and temporal patterns of seafloor methane seepage over multi-million-year time scales are still poorly understood. The microbial oxidation of methane can store carbon in sediments through precipitation of carbonate minerals, thus providing a record o...
Article
Full-text available
Over the last decade, there has been a resurgence of interest in the climatic and tectonic mechanisms that drove the Messinian salinity crisis (MSC) and the associated deposition of thick evaporites. The MSC represents an unprecedented palaeoceanographic change that led to a very short (c. 640 kyr) ecological and environmental crisis. However, acro...
Article
Full-text available
Understanding triggers and evolution of post-depositional sediment intrusion is of major importance to decrease the risk associated with hazards to infrastructure and environment from events such as submarine landslides and fluid escape. Whereas deep-sourced intrusions (>1 km) are widely documented, early burial examples are poorly recognized and h...

Tectonically controlled topography influences deep-water sedimentary systems. Using 3-D seismic reflection data from the Levant Basin, eastern Mediterranean Sea, we investigate the spatial and temporal evolution of bedforms on a deep-water fan cut by an active normal fault. In the footwall, the fan comprises cyclic steps and antidunes along its axi...

Despite having a profound impact on the structural evolution of salt‐influenced basins, spatial and temporal variations in rates of salt flow, and their key controls, remain largely unconstrained. We investigate early stage salt‐detached gliding using a 3D seismic data set from the Levant Margin in the Eastern Mediterranean, where gravitational ins...

We investigate early-stage salt-detached gliding using a 3D seismic dataset from the Levant Margin in the Eastern Mediterranean, where gravitational instability due to margin uplift has caused north-westward translation of the Messinian salt sheet and its Plio-Pleistocene clastic overburden. Large, NE-trending, base-salt anticlines have allowed the...

Methane seepage at the seafloor is a source of carbon in the marine environment and has long been recognized as an important window into the deep geo-, hydro-, and bio-spheres. However, the processes and temporal patterns of natural methane emission over multi-million-year time scales are still poorly understood. The microbially-mediated methane ox...

A remarkable exposure of carbonate pipe-like and slab concretions occurs along the Enza riverbanks on the northern Apennines foothills (Italy). Based upon geochemical and field evidences, their genesis has been attributed to microbial-governed carbonate precipitation from hydrocarbon-enriched fluids. The pipe-like concretions are thus interpreted a...
