Pegmatite lithium deposits formed within low-temperature country rocks by Jinsheng Zhou, Qiang Wang, He Wang, Jinlong Ma, Guanhong Zhu, Le Zhang

“…Here we show that Li contents in pegmatites are controlled not only by the initial Li contents in pegmatite melts but also by the temperature of the surrounding country rocks at the time of pegmatite emplacement. Lithium-mineralized pegmatites form preferentially when Li-rich pegmatite melts intrude low-temperature country rocks.…”

The geology of the Aracruz pluton (Espírito Santo, Brazil), a Cambrian post-orogenic intrusion in the aftermath of Gondwana amalgamation by Andrea Galli, Max W. Schmidt, Valdecir de Assis Janasi, Felix Soormann, Clara Talca Onken, Alexandra Aregger, Tobias Hendrickx, Samuel Huber, Zoe Kok, Emanuel Pestalozzi, Tabea Stäheli, Luka Wanner, Vinicius Louro

“…Steep-dipping concentric magmatic foliation, magmatic foliation parallel to tectonic foliation in the country rock, the noritic core, and the irregular charnockite and quartz-diorite band alignment suggest buoyancy-driven diapirism as emplacement mechanism. …”

The geological setting of Matra ore deposit (France): insights from lithostratigraphy and polyphase deformation history by Danis Ionut Filimon, Giacomo Vannucci, Alessandro La Rosa, Vincenzo Zarone, Maria Di Rosa

“…Arsenic sulfide mineralization in Matra mine (southern Alpine Corsica) is hosted by two tectonic units belonging to the Schistes Lustrés Complex. Country rocks include a Jurassic ophiolitic sequence and related sedimentary covers, which were metamorphosed. …”

Fractionation of Rare Earth Elements in Greisen and Hydrothermal Veins Related to A-Type Magmatism by Mikael Tillberg, Olga M. Maskenskaya, Henrik Drake, Johan K. Hogmalm, Curt Broman, Anthony E. Fallick, Mats E. Åström

“…Low calculated ∑REE concentration for bulk vein (15 ppm) compared to greisen (75 ppm), country rocks (173–224 ppm), and the intruding granite (320 ppm) points to overall low REE levels in the hydrothermal fluids emanating from the granite. …”
