    Research interests



    My research interests include thermochronology and petrophysics, and projects within the thermal modeling group have focussed on the thermal histories of neoproterozoic plutons in Province Borborema (PB) over time periods of 600 Ma. Many geological processes alter the temperatures of minerals, and quantification of that temperature change can assist in understanding the nature of the governing mechanics behind the processes. The problems we have been addressing in Umarizal (pluton of PB) include how can we use thermochronological informations, thermobarometry and numerical models techniques to accurately reconstruct the igneous histories in Province Borborema over long time scales (e.g. 600 million years, and more) ? Since 2014, we have focussed our research on thermal effects of igneous intrusions, it have the potential to recover continuous thermal evolution of indicators mineral phases and therefore perhaps probe further back in time. The Province Borborema have been used as a natural laboratory because they are a superb example of it has experienced volcanism, plutonism, terrane collision and dispersed periods of compression and extension.
