His primary areas of study are Geochemistry, Zircon, Geochronology, Craton and Archean. His studies deal with areas such as Foreland basin, Batholith and Supercontinent as well as Geochemistry. The various areas that Léo Afraneo Hartmann examines in his Zircon study include Metamorphic rock, Orogeny, Sedimentary rock, Provenance and Gondwana.
In his research on the topic of Geochronology, Basalt and Igneous rock is strongly related with Volcanic rock. His research in Craton intersects with topics in Titanite, Pyrite and Terrane. His study in Archean is interdisciplinary in nature, drawing from both Earth science, Island arc and Proterozoic.
Léo Afraneo Hartmann spends much of his time researching Geochemistry, Zircon, Basalt, Craton and Geochronology. As part of his studies on Geochemistry, he frequently links adjacent subjects like Petrology. Léo Afraneo Hartmann has researched Zircon in several fields, including Batholith, Gneiss, Mineralogy and Ophiolite.
As a member of one scientific family, Léo Afraneo Hartmann mostly works in the field of Craton, focusing on Terrane and, on occasion, Gondwana. The study incorporates disciplines such as Orogeny and Felsic in addition to Geochronology. His biological study deals with issues like Crust, which deal with fields such as Foreland basin.
His main research concerns Geochemistry, Zircon, Basalt, Volcano and Ophiolite. His Geochemistry study which covers Oceanic crust that intersects with Tourmaline. His Zircon study combines topics from a wide range of disciplines, such as Rodinia, Craton, Fold and thrust belt, Geochronology and Archean.
His studies in Craton integrate themes in fields like Precambrian and Continental crust. His Basalt study combines topics in areas such as Rhyodacite, Geode, Mineralogy, Cuesta and Breccia. Léo Afraneo Hartmann has included themes like Metasomatism and Mantle in his Ophiolite study.
Léo Afraneo Hartmann mainly focuses on Geochemistry, Zircon, Craton, Tonian and Ophiolite. His Geochemistry study combines topics from a wide range of disciplines, such as Foreland basin and Terrane. His Zircon research includes elements of Fold and thrust belt, Petrology and Archean.
His Petrology research incorporates themes from Suture, Rodinia and Geochronology. Precambrian, Basement, Provenance, Sedimentary basin and Metavolcanic rock is closely connected to Sedimentary depositional environment in his research, which is encompassed under the umbrella topic of Archean. His Craton research is within the category of Paleontology.
