The Lages diatremes: mineral composition and petrological implications
Anais da Academia Brasileira de Ciências, 2007 Chemical data of heavy minerals from Lages diatremes in southern Brazil have been studied with the aim of characterizing the sample source(s). Three groups of minerals are recognized: I) aluminian-chromian pyroxene, pyrope garnet and chromian spinel ...

Heat transfer by fluids in granulite metamorphism [PDF]
The thermal role of fluids in granulite metamorphism was presented. It was shown that for granulites to be formed in the middle crust, heat must be advected by either magma or by volatile fluids, such as water or CO2.
