Jim D. Marshall focuses on Paleontology, Ordovician, Isotopes of oxygen, Carbon cycle and Total organic carbon. His work is connected to Gondwana, Cretaceous, Petrography, Stratotype and Biostratigraphy, as a part of Paleontology. His research in Petrography intersects with topics in Sedimentary depositional environment and Diagenesis.
His Ordovician study combines topics in areas such as Marinoan glaciation, Sea level and Ice sheet. His Isotopes of oxygen research is multidisciplinary, incorporating elements of Earth science and Lake water. His Geochemistry research incorporates themes from Sediment and δ18O.
Jim D. Marshall mostly deals with Paleontology, Diagenesis, Oceanography, Calcite and Geochemistry. The various areas that Jim D. Marshall examines in his Diagenesis study include Sedimentary rock, Dolomite, Petrography, Sedimentary depositional environment and Meteoric water. Jim D. Marshall has included themes like Atmospheric circulation, Sediment and Isotopes of oxygen in his Oceanography study.
As part of the same scientific family, Jim D. Marshall usually focuses on Isotopes of oxygen, concentrating on δ18O and intersecting with Bog and Hydrology. His Calcite research includes themes of Concretion, Outcrop and Isotope geochemistry. His primary area of study in Geochemistry is in the field of Carbonate rock.
His scientific interests lie mostly in Paleontology, Diagenesis, Physical geography, Calcite and Facies. His Diagenesis study incorporates themes from Sedimentary depositional environment and Petrography. Jim D. Marshall interconnects Stage, Ecological succession, Delta front and Cretaceous in the investigation of issues within Petrography.
His Physical geography study integrates concerns from other disciplines, such as Organic matter, Total organic carbon and Holocene. His Calcite research integrates issues from Outcrop, δ18O, Ostracod, Concretion and Sedimentary structures. His δ18O research focuses on Abundance and how it relates to Oceanography.
His primary areas of investigation include Calcite, Oceanography, Ostracod, Paleontology and Atlantic multidecadal oscillation. His work deals with themes such as Outcrop, Diagenesis, Concretion and Sedimentary structures, Sedimentary depositional environment, which intersect with Calcite. His Oceanography study combines topics from a wide range of disciplines, such as Atmospheric circulation and Isotopes of oxygen.
His Ostracod research incorporates elements of Clastic rock, Lagerstätte, Lithification, Facies and Horizon. His works in Sedimentary rock and Taphonomy are all subjects of inquiry into Paleontology. His biological study spans a wide range of topics, including δ18O, Abundance and Sediment.
