Overview

What is he best known for?

The fields of study he is best known for:

Paleontology
Ecology
Sedimentary rock

Stephen E. Grasby mainly focuses on Paleontology, Permian–Triassic extinction event, Extinction event, Early Triassic and Permian. His work on δ18O expands to the thematically related Paleontology. Extinction event is the subject of his research, which falls under Extinction.

The study incorporates disciplines such as Earth science and Large igneous province in addition to Extinction. He combines subjects such as Total organic carbon, Chemostratigraphy and Anoxic waters with his study of Early Triassic. His studies deal with areas such as Volcano, Sedimentary rock and Oceanography, Arctic as well as Permian.

His most cited work include:

On the causes of mass extinctions (174 citations)
On the causes of mass extinctions (174 citations)
Latest Permian mercury anomalies (155 citations)

What are the main themes of his work throughout his whole career to date?

Paleontology, Geochemistry, Permian, Arctic and Extinction event are his primary areas of study. The concepts of his Paleontology study are interwoven with issues in Permian–Triassic extinction event and Chemostratigraphy. His work deals with themes such as Siberian Traps and Oceanography, which intersect with Permian–Triassic extinction event.

His research integrates issues of Flood basalt, Structural basin and Aquifer, Groundwater in his study of Geochemistry. His Arctic research is multidisciplinary, incorporating elements of Ridge and Spring. His Extinction event research incorporates elements of Ordovician, Phanerozoic, Earth science and Large igneous province.

He most often published in these fields:

Paleontology (46.28%)
Geochemistry (30.17%)
Permian (27.27%)

What were the highlights of his more recent work (between 2018-2021)?

Geochemistry (30.17%)
Permian (27.27%)
Large igneous province (11.98%)

In recent papers he was focusing on the following fields of study:

Stephen E. Grasby mainly investigates Geochemistry, Permian, Large igneous province, Extinction event and Paleontology. His Geochemistry research includes elements of Seawater, Organic matter and Sediment. His work in the fields of Early Triassic overlaps with other areas such as Transient.

He has included themes like Sedimentary rock, Volcanism, Glacial period and Ordovician in his Large igneous province study. His study in Extinction event is interdisciplinary in nature, drawing from both Geologic record, Disturbance, Phanerozoic and Earth science. His work carried out in the field of Paleontology brings together such families of science as Permian–Triassic extinction event, Chemostratigraphy and Arctic.

Between 2018 and 2021, his most popular works were:

Mercury as a proxy for volcanic emissions in the geologic record (58 citations)
Terrestrial sources as the primary delivery mechanism of mercury to the oceans across the Toarcian Oceanic Anoxic Event (Early Jurassic) (52 citations)
Global mercury cycle during the end-Permian mass extinction and subsequent Early Triassic recovery (26 citations)
