Marcasite at the Permian‐Triassic Transition
Geophysical Monograph Series, Page 377-399., 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.

Grain-Size Analysis of Ancient Deep-Marine Sediments Using Laser Diffraction
Frontiers in Earth Science, 2022 Grain-size analysis of siliciclastic sedimentary rocks provides critical information for interpreting flow dynamics and depositional environments in sedimentary systems and for analysing reservoir quality of sandstone.

Great earthquakes along the Western United States continental margin: implications for hazards, stratigraphy and turbidite lithology [PDF]
Natural Hazards and Earth System Sciences, 2012 We summarize the importance of great earthquakes (<i>M</i><sub>w</sub> ≳ 8) for hazards, stratigraphy of basin floors, and turbidite lithology along the active tectonic continental margins of the Cascadia subduction ...

Stratigraphy of the central parts of the Palaeoproterozoic Tampere Schist Belt, southern Finland: review and revision [PDF]
Bulletin of the Geological Society of Finland, 1998 The arc-type Palaeoproterozoic volcanic-sedimentary Tampere Schist Belt (TSB), close to the centre of the Svecofennian Orogen, comprises an E-W-striking major synform in its central parts.

A Review of Event Deposits in Lake Sediments
Quaternary, 2022 Event deposits in lake sediments provide invaluable chronicles of geodynamic and climatic natural hazards on multi-millennial timescales. Sediment archives are particularly useful for reconstructing high-impact, low-frequency events, which are rarely ...
