Overview

What is he best known for?

The fields of study he is best known for:

  • Volcano
  • Basalt
  • Sedimentary rock

His primary scientific interests are in Geochemistry, Paleontology, Volcano, Pyroclastic rock and Volcanic rock. His work deals with themes such as Sedimentary depositional environment, Stratigraphy and Facies, which intersect with Geochemistry. His research integrates issues of Volcanism, Earth science and Geomorphology in his study of Volcano.

His work in Earth science addresses subjects such as Volcanic pipe, which are connected to disciplines such as Pyroclastic fall and Pyroclastic surge. His Pyroclastic rock research incorporates elements of Pumice, Caldera, Magma and Diatreme. Raymond Alexander Fernand Cas combines subjects such as Turbidity current and Debris flow with his study of Volcanic rock.

His most cited work include:

  • Volcanic successions, modern and ancient (843 citations)
  • Volcanic Successions Modern and Ancient: A geological approach to processes, products and successions (264 citations)
  • Subaqueous pyroclastic flows and ignimbrites: an assessment (135 citations)

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

The scientist’s investigation covers issues in Geochemistry, Pyroclastic rock, Volcano, Volcanic rock and Petrology. His Geochemistry study integrates concerns from other disciplines, such as Facies and Geomorphology. The concepts of his Geomorphology study are interwoven with issues in Eruption column, Volcanic ash, Pyroclastic fall, Pyroclastic surge and Breccia.

His studies deal with areas such as Pumice, Caldera, Igneous rock and Clastic rock as well as Pyroclastic rock. His work carried out in the field of Volcano brings together such families of science as Tectonics and Earth science. The study incorporates disciplines such as Lapilli and Maar in addition to Phreatomagmatic eruption.

He most often published in these fields:

  • Geochemistry (63.71%)
  • Pyroclastic rock (39.66%)
  • Volcano (33.76%)

What were the highlights of his more recent work (between 2012-2020)?

  • Geochemistry (63.71%)
  • Volcano (33.76%)
  • Pyroclastic rock (39.66%)

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

His primary areas of investigation include Geochemistry, Volcano, Pyroclastic rock, Volcanic rock and Basalt. His Geochemistry research is multidisciplinary, incorporating perspectives in Geomorphology and Yilgarn Craton. His Geomorphology research integrates issues from Eruption column, Pyroclastic fall and Dense-rock equivalent.

His Volcano study combines Seismology and Paleontology studies. The Pyroclastic rock study combines topics in areas such as Clastic rock, Petrology, Facies, Caldera and Kimberlite. Raymond Alexander Fernand Cas focuses mostly in the field of Basalt, narrowing it down to matters related to Zircon and, in some cases, Terrane.

Between 2012 and 2020, his most popular works were:

  • Calibrating the pTRM and charcoal reflectance (Ro%) methods to determine the emplacement temperature of ignimbrites: Fogo A sequence, São Miguel, Azores, Portugal, as a case study (53 citations)
  • The origin of a large (> 3 km) maar volcano by coalescence of multiple shallow craters: Lake Purrumbete maar, southeastern Australia (52 citations)
  • Eruption processes and deposit characteristics at the monogenetic Mt. Gambier Volcanic Complex, SE Australia: implications for alternating magmatic and phreatomagmatic activity (48 citations)

In his most recent research, the most cited papers focused on:

  • Volcano
  • Basalt
  • Sedimentary rock

Raymond Alexander Fernand Cas mainly focuses on Geochemistry, Volcano, Volcanic rock, Phreatomagmatic eruption and Basalt. In his work, Archean, Felsic and Ultramafic rock is strongly intertwined with Yilgarn Craton, which is a subfield of Geochemistry. He works mostly in the field of Volcano, limiting it down to topics relating to Sedimentology and, in certain cases, Intraplate earthquake, Volcanic explosivity index, Paleomagnetism and Stratigraphy.

His research investigates the link between Phreatomagmatic eruption and topics such as Earth science that cross with problems in Volcanic glass and Peperite. The various areas that he examines in his Basalt study include Magma chamber, Mantle and Crust. His Pyroclastic rock research incorporates themes from Caldera, Effusive eruption and Geomorphology.
