Michael R. Carroll mainly investigates Magma, Mineralogy, Sulfur, Andesite and Volcano. His research investigates the link between Magma and topics such as Igneous rock that cross with problems in Volatiles and Hornblende. His Mineralogy research is multidisciplinary, incorporating perspectives in Fugacity and Analytical chemistry.

His Sulfur study integrates concerns from other disciplines, such as Inorganic chemistry, Sulfate, Mineral redox buffer and Solubility. His research integrates issues of Lava, Magma chamber and Plagioclase in his study of Andesite. His work is dedicated to discovering how Volcano, Petrology are connected with Lava dome and other disciplines.

His most cited work include:

  • An Experimental Study of the Influence of Oxygen Fugacity on Fe-Ti Oxide Stability, Phase Relations, and Mineral—Melt Equilibria in Ferro-Basaltic Systems (418 citations)
  • Solubilities of sulfur, noble gases, nitrogen, chlorine, and fluorine in magmas (394 citations)
  • Remobilization of Andesite Magma by Intrusion of Mafic Magma at the Soufriere Hills Volcano, Montserrat, West Indies (379 citations)

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

His primary areas of investigation include Mineralogy, Geochemistry, Magma, Analytical chemistry and Solubility. His Mineralogy study combines topics from a wide range of disciplines, such as Crystallization, Fluid inclusions, Magma chamber, Plagioclase and Peralkaline rock. His Geochemistry course of study focuses on Alkali feldspar and Mineral and Crystallography.

His work carried out in the field of Magma brings together such families of science as Decompression, Petrology and Phenocryst. His research in Analytical chemistry intersects with topics in Mineral redox buffer, Oxidation state and Silicate. His studies in Solubility integrate themes in fields like Thermal diffusivity, Fugacity, Aqueous solution, Infrared spectroscopy and Diffusion.

He most often published in these fields:

  • Mineralogy (30.93%)
  • Geochemistry (27.84%)
  • Magma (26.80%)

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

  • Geochemistry (27.84%)
  • Alkali feldspar (10.31%)
  • Crystallization (12.37%)

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

Michael R. Carroll mostly deals with Geochemistry, Alkali feldspar, Crystallization, Peralkaline rock and Magma. As part of one scientific family, he deals mainly with the area of Geochemistry, narrowing it down to issues related to the Solubility, and often Inorganic chemistry. His Crystallization study combines topics in areas such as Chemical physics, Crystal growth and Trace element.

His Magma research incorporates elements of Petrology and Melt inclusions. His Petrology research is multidisciplinary, incorporating elements of Rhyolite, Supercooling, Explosive eruption and Nucleation. His study in Analytical chemistry is interdisciplinary in nature, drawing from both Sulfur, Fugacity, Hauyne and Silicate.

Between 2016 and 2021, his most popular works were:

  • Circulation path of thermal waters within the Laga foredeep basin inferred from chemical and isotopic (δ18O, δD, 3H, 87Sr/86Sr) data (13 citations)
  • The effect of diffusive re-equilibration time on trace element partitioning between alkali feldspar and trachytic melts (9 citations)
  • Vitrification treatment of municipal solid waste bottom ash (6 citations)
