EN | For far too long has the Guanhães Block been viewed as an empty square in the evolutionary models of the Araçuaí-West-Congo Orogen. A new publication in Gondwana Research uses petrochronological strategies with dating of multiple mineral phases, traditional thermobarometry and phase-diagram modeling to understand the conditions in which the main pervasive foliation wasContinue reading “[Article] Implications of the dominant LP–HT deformation in the Guanhães Block for the Araçuaí West-Congo Orogen evolution”

[Article] (U)HT rocks from Madagascar
EN | Madagascar has by spectacular (U)HT rocks. Titanite in these rocks records the waning stages of UHTM followed by pervasive hydrothermal activity associated with U–Th and phlogopite mineralization. Contribution by the researcher Robert Holder (@thats.so.meta).Read more in Holder and Hacker (2019). Fluid-driven resetting of titanite following ultrahigh-temperature metamorphism in southern Madagascar. Chemical Geology! Rochas deContinue reading “[Article] (U)HT rocks from Madagascar”
