American Mineralogist:
Experimental hydrogenation of pure and Cr-doped rutile at variable temperature, pressure, and oxygen fugacity
Mona Lueder, Jörg Hermann, Paolo A. Sossi
Hydrogen is retained to much higher temperatures than has been suggested by previous studies.

American Mineralogist:
From hydroxylbastnäsite to bastnäsite: A crystal chemistry perspective of the incomplete solid solution
Qifa Zhong, Jingui Xu, Wei Zhao, Dongzhou Zhang, Shanrong Zhang, Kai Wang, Bin Fu, Wenge Zhou, Dawei Fan

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.

American Mineralogist:
Apatite from metaluminous to peralkaline high-silica rhyolites in Yunshan Caldera (SE China): Implications for the evolution of magmatic systems
Wentao Hong, et al.
Apatite inclusions record heterogeneous crystal mush conditions.

Mineral Monday:
MSA Outreach at GSA and Other Meetings
By Andrea Koziol
At GSA (Geological Society of America) meetings MSA has a booth (Fig. 1) with books for sale, but also displays of interesting minerals, their occurrences, and uses.

Thin Section Thursday! Photo and caption by Matthew Cruz, UG student: Unakite is a metamorphic rock primarily composed of Epidote, Orthoclase, and Quartz. The vibrant colors (XPL) come from the interference colors of Epidote. #unakite #thinsection #thinsectionthursday
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:
Formation pathways of Zn-spinel nanoparticles in Zn-contaminated soils and sediments
Michael Schindler, Tessa Warkentine, Xinyang Li
