Thin Section Thursday! Image and caption contributed by Bjorn Isaacson, UG student at James Madison University. Eclogite: Starting as mafic basalt, through high P &T this rock reached the eclogite metamorphic facies creating the large rich isotropic garnets. #thinsectionthursday #eclogite
American Mineralogist:
Hydrothermal rutile as a recorder of fluid evolution and W mineralization: Insights from the Northern Baoshan Block, China
Xiaobo Si, et al.
Rutile is an effective carrier for W, preventing its loss in F- and B-rich magmatic-hydrothermal systems.
