Sebastian “Batzi” Fischer is a hard rock geologist with a particular interest in metamorphic petrology. Currently a PhD student at the University of St Andrews, he is looking at the mineral zircon in mafic metamorphic rocks, with a focus on the influence that partial melting has on the zircons’ isotopic composition. For my PhD project […]
A lot of people, including many non-geologists (even Beyoncé), are aware of the famous detrital Hadean zircons from the Jack Hills of Western Australia, which represent the oldest terrestrial minerals yet found (up to 4.37 Ga). The oldest crystalline basement rocks are arguably an equally important source of information regarding Earth’s earliest history. During my […]

In addition to rocks, Labrador also is known for: Bears… Wide expanses of pine trees… Blueberries! Most of the best exposures in Labrador are to be found in quarries. These quarries are large […]

I am trying to understand the changes in the chemistry of the continental crust due to […]
