Zircon Hf-O isotopic fingerprints in accretionary vs. collisional orogenesis Zircon Hf isotopes are able to identify the relative proportion of mantle and crustal inputs to magma systems, and different Hf isotopic patterns can be expected in different tectonic settings. Coupled …
Leveraging seismic data quality metrics for network supervision and sensitive earthquake detection In earthquake seismology, the last decade has led to ever growing datasets of continuous seismograms being recorded, stored, and made openly available. These ever increasing datasets (e.g., …
Improving modelling of seismic images through Point-Spread Function-based convolution Seismic images are generated when a source at the Earth’s surface initiates a pressure wave which travels through the Earth’s subsurface. As the wave hits layer boundaries in the Earth’s interior, …
What causes volcanic gaps in subduction zones? Insights from South central Alaska
Deep-water syn-rift sedimentary response to alternating Late Quaternary palaeoenvironments in the Gulf of Corinth (Greece) Relatively few detailed studies exist of rift axis depositional systems and the controls on their sedimentology and stratigraphy. Cores from the IODP Expedition 381 (Corinth …
Faulting at near-surface conditions: an example from unconsolidated deposits in the Central Apennines
"Geology fieldwork in the High Arctic – some pictures taken during the 2021 Sequence Stratigraphy course on Svalbard” By Flávio Norberto de Almeida Junior “Picture report from new remote seismic stations on Svalbard - how we worked against fog, ice, …

Coupling crustal-scale rift architecture with rifted margin salt tectonics: a geodynamic modelling approach Many rifted passive margins are associated with widespread and thick evaporite (i.e., salt) deposits, and pronounced syn-and post-rift salt tectonics. The majority and largest salt basins known-to-date …
Large Igneous Provinces, hydrovolcanism and paleoenvironments/paleohydrology: lessons from the Paraná Basin in South Brazil In many continental flood basalt provinces (CFBPs), primary mafic volcaniclastic deposits have been shown to be significant counterparts of better-known effusive (lava flow) facies, a notion …
Quaternary basin fill and evolution of the North Sea Basin: A synthesis of sequence stratigraphy and basin modeling techniques by Baig, Irfan; Faleide, Jan Inge; Aagaard, Per; Chuahan, Teena; Hjelstuen, Berit Oline Blihovde & Sejrup, Hans Petter
