Overview

What is he best known for?

The fields of study he is best known for:

  • Sedimentary rock
  • Paleontology
  • Igneous rock

Alcides N. Sial mainly investigates Paleontology, Geochemistry, Sedimentary rock, Chemostratigraphy and Pluton. The Craton, Glacial period, Cretaceous and Siliciclastic research Alcides N. Sial does as part of his general Paleontology study is frequently linked to other disciplines of science, such as Excursion, therefore creating a link between diverse domains of science. His work carried out in the field of Geochemistry brings together such families of science as Batholith and Proterozoic.

The concepts of his Chemostratigraphy study are interwoven with issues in Corumbella and Group. His studies in Pluton integrate themes in fields like Dike, Petrology, Shear zone, Magma and Terrane. His study looks at the relationship between Archean and fields such as Zircon, as well as how they intersect with chemical problems.

His most cited work include:

  • 4.4 billion years of crustal maturation: oxygen isotope ratios of magmatic zircon (705 citations)
  • Integrated correlation of the Vendian to Cambrian Arroyo del Soldado and Corumbá Groups (Uruguay and Brazil): palaeogeographic, palaeoclimatic and palaeobiologic implications (151 citations)
  • Soft-sediment deformation at the base of the Neoproterozoic Puga cap carbonate (southwestern Amazon craton, Brazil): Confirmation of rapid icehouse to greenhouse transition in snowball Earth (141 citations)

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

The scientist’s investigation covers issues in Geochemistry, Paleontology, Chemostratigraphy, Pluton and Isotopes of carbon. Alcides N. Sial interconnects Batholith, Epidote and Porphyritic in the investigation of issues within Geochemistry. His is doing research in Craton, Glacial period, Cretaceous, Precambrian and Sedimentary rock, both of which are found in Paleontology.

His Craton research is multidisciplinary, incorporating elements of Cap carbonate, Basement and Carbonate platform. His study in Pluton is interdisciplinary in nature, drawing from both Petrology, Shear zone, Hornblende and Terrane. Alcides N. Sial combines subjects such as Structural basin, δ18O and Supergroup with his study of Isotopes of carbon.

He most often published in these fields:

  • Geochemistry (55.87%)
  • Paleontology (34.41%)
  • Chemostratigraphy (13.77%)

What were the highlights of his more recent work (between 2016-2021)?

  • Geochemistry (55.87%)
  • Paleontology (34.41%)
  • δ13C (6.88%)

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

Alcides N. Sial mostly deals with Geochemistry, Paleontology, δ13C, Chemostratigraphy and Sedimentary rock. His Geochemistry research is multidisciplinary, incorporating perspectives in Structural basin, Batholith and Porphyritic. His biological study spans a wide range of topics, including δ18O, Oceanography, Coral, Caiman latirostris and Atoll.

His Chemostratigraphy research includes themes of Carbon isotope excursion, Phanerozoic, Large igneous province and Geochronology. His Sedimentary rock research also works with subjects such as

  • Siliciclastic together with Meteoric water, Aragonite and Outcrop,
  • Organic matter which connect with Continental shelf and δ15N. His Mafic research is multidisciplinary, relying on both Amphibole and Zircon.

Between 2016 and 2021, his most popular works were:

  • Cloudina-Corumbella-Namacalathus association from the Itapucumi Group, Paraguay: Increasing ecosystem complexity and tiering at the end of the Ediacaran (20 citations)
  • Ediacaran paleoenvironmental changes recorded in the mixed carbonate-siliciclastic Bambuí Basin, Brazil (17 citations)
  • Trace elements and isotope geochemistry (C, O, Fe, Cr) of the Cauê iron formation, Quadrilátero Ferrífero, Brazil: Evidence for widespread microbial dissimilatory iron reduction at the Archean/Paleoproterozoic transition (16 citations)

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

  • Sedimentary rock
  • Paleontology
  • Igneous rock

His primary scientific interests are in Paleontology, Geochemistry, Cap carbonate, Basement and Sedimentary depositional environment. His Paleontology study incorporates themes from Ecology, δ18O and δ13C. His work deals with themes such as Ecosystem and Anoxic waters, which intersect with Geochemistry.

He usually deals with Cap carbonate and limits it to topics linked to Facies and Dolostone, Unconformity, Snowball Earth and Marinoan glaciation. His Sedimentary depositional environment study which covers Rodinia that intersects with Stromatolite and Chemostratigraphy. His Siliciclastic study also includes

  • Outcrop together with Sedimentary rock,
  • Authigenic which connect with Dolomite.
