How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
PhD candidate at The University of Queensland (Australia). I am interested in how subduction zones initiates and recycle fluid and solid phases back to the surface. I'm also working on the evolution of the Precambrian orogens. Currently, I am studying ophiolites in Australia, New Caledonia and New Zealand.
The late Early Paleozoic volcanic rocks in the East Kunlun orogen are crucial to determining collisional processes related to the evolution of the Proto-Tethys Ocean. We report new zircon U-Pb ages, whole-rock geochemistry and Sr-Nd isotopes from these volcanic rocks and constrain their tectonic setting and magmatic processes. This volcanic suite c...
Phase diagram modelling and U-Pb monazite ages reveal a clockwise Pressure-Temperature-time metamorphic evolution in the Paranaguá Terrane (Ribeira Belt – SE Brazil) and characterized important tectonic events. Comparisons of our dataset with the Dom Feliciano and Kaoko belts indicate a contrasting metamorphic evolution of South American and Africa...
Voluminous flux of a hydrous component from subducting oceanic lithosphere into the forearc mantle and its contribution to arc magmas have long been recognised but the transfer of solid-phase materials has received less consideration. Although xenocrystic zircons are known from some arc magmas and ophiolitic chromitites their origins remain enigmat...
Dominantly Mesozoic to Proterozoic xenocrystic zircons extracted from Tiébaghi chromitite coexist with a well-defined population (30%) of Eocene magmatic grains (U-Pb: 48.2 ± 1.1 Ma). Since Eocene zircons are absent in the peridotite host rock and are accompanied by rare rutiles with the same age range, it is suggested that both are derived from th...
The Capiru Group is a Neoproterozoic metasedimentary unit that crops out in the Curitiba terrane, Southern Ribeira Belt, Brazil. A detailed geological mapping of this unit was performed during 2016 to 2020. Original interpretations and the new geological map were compiled and integrated with the past field data of the state (MINEROPAR) and national...
The Paranaguá Terrane is mainly constituted by an arc-related granitic complex, spread in a large NE-SW elongated stripe, located in Southern Ribeira Belt, Southeastern Brazil. The country rocks of these granites occur as a disrupted folded belt composed of metasedimentary rocks and gneissic-migmatitic rocks in split basement nuclei. The integratio...
This report details the geology mapped of the region of Campestre in northeastern portion of the Paraná State (Brazil)
Geological Map developed during the geological mapping discipline in the course of geology in the Federal University of Paraná.
Research and Development Project whose main objective is to understand the depositional environment and the geochemical signs of clay minerals, microbial carbonates, travertines and tufas, as well as their permoporous properties as reservoir rock, at different scales.
This work has as main objective the metamorphic and structural understanding of the metasediments of the Rio das Cobras Sequence and its relationship with the adjacent units, aiming to perform a tectonic modeling in the context of the Paranaguá Terrain, to better understand the evolution in the Southern Ribeiro Belt. In order to achieve this main objective, it is necessary to perform other secondary tasks, such as: a) Determination of the occurrence of different lithotypes and mappable units, in an attempt to propose a stratigraphic organization for the Sequence Rio das Cobras; b) Characterization of the metamorphism, metamorphic facies and thermobarometric evolution of the Sequence Rio das Cobras, trying to understand the development of shear zones and the characteristics of the collision event; c) Study of provenance of metasediments by means of U-Pb dating in detrital zircon in rocks of silissiclástica origin, for comparison with regional geochronological results and determination of possible sources areas; d) The tectonic context of the Rio das Cobras Sequence with the granitoids and basement rocks, looking for kinematic indicators and their deformation in time and space.
