Fellow of the Geological Society of America

Overview

What is he best known for?

The fields of study he is best known for:

  • Paleontology
  • Sedimentary rock
  • Ecology

The scientist’s investigation covers issues in Paleontology, Cap carbonate, Proterozoic, Precambrian and Glacial period. His research integrates issues of Doushantuo Formation and Isotopes of carbon in his study of Paleontology. His Cap carbonate study integrates concerns from other disciplines, such as Isotopes of strontium, Chemostratigraphy, Riphean and Marinoan glaciation.

His studies deal with areas such as Geochemistry, Phanerozoic, Cenozoic and Unconformity as well as Proterozoic. His Precambrian research incorporates elements of Corumbella and Namacalathus. His Glacial period research focuses on Diagenesis and how it connects with Craton.

His most cited work include:

  • A Neoproterozoic Snowball Earth (1867 citations)
  • Neoproterozoic variations in the C-isotopic composition of seawater: stratigraphic and biogeochemical implications. (700 citations)
  • A Whiff of Oxygen Before the Great Oxidation Event (661 citations)

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

His scientific interests lie mostly in Paleontology, Geochemistry, Proterozoic, Glacial period and Chemostratigraphy. His Paleontology study frequently draws parallels with other fields, such as Isotopes of carbon. In his study, which falls under the umbrella issue of Geochemistry, Environmental chemistry is strongly linked to Mineralogy.

His work focuses on many connections between Proterozoic and other disciplines, such as Acritarch, that overlap with his field of interest in Group. Alan J. Kaufman interconnects Fold and Unconformity in the investigation of issues within Glacial period. His Chemostratigraphy research includes elements of Doushantuo Formation, Biostratigraphy, Dolomite, Diagenesis and Sedimentary depositional environment.

He most often published in these fields:

  • Paleontology (57.58%)
  • Geochemistry (27.27%)
  • Proterozoic (25.45%)

What were the highlights of his more recent work (between 2016-2020)?

  • Geochemistry (27.27%)
  • Paleontology (57.58%)
  • Chemostratigraphy (18.79%)

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

Alan J. Kaufman mainly investigates Geochemistry, Paleontology, Chemostratigraphy, Diagenesis and Doushantuo Formation. His biological study spans a wide range of topics, including Oil shale, Cretaceous, Isotopes of carbon, Proterozoic and Isotopes of strontium. He combines topics linked to Carbon cycle with his work on Paleontology.

He has researched Chemostratigraphy in several fields, including Petrography and Dolomite. His Diagenesis research is multidisciplinary, relying on both Sedimentary rock, Terrigenous sediment, Trace element and Radiogenic nuclide. His Doushantuo Formation study combines topics in areas such as Glacial period, Deglaciation, Stratification and Diamictite.

Between 2016 and 2020, his most popular works were:

  • Extensive marine anoxia during the terminal Ediacaran Period. (60 citations)
  • Sedimentology and chemostratigraphy of the terminal Ediacaran Dengying Formation at the Gaojiashan section, South China. (21 citations)
  • Uranium isotope evidence for limited euxinia in mid-Proterozoic oceans (18 citations)

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

  • Paleontology
  • Sedimentary rock
  • Ecology

Alan J. Kaufman mainly focuses on Geochemistry, Chemostratigraphy, Facies, Paleontology and Proterozoic. Geochemistry is represented through his Sedimentary rock and Isotopes of oxygen research. His studies in Chemostratigraphy integrate themes in fields like Trace element, Dolomitization, Diagenesis and Geochronology.

As part of his studies on Paleontology, Alan J. Kaufman often connects relevant areas like Cycling. His Proterozoic study combines topics from a wide range of disciplines, such as Seafloor spreading, Carbonate rock, Oil shale and Anoxic waters. To a larger extent, Alan J. Kaufman studies Glacial period with the aim of understanding Cap carbonate.
