Tectonic Tremor Explained by Successive Ruptures of Clustered Quartz‐Filled Shear Veins

Geophysical Research Letters
A tectonic tremor is a successive seismic signal observed along plate boundaries in subduction zones. However, the source processes and mechanisms responsible for the tremor remain unclear. Quartz‐filled shear and extension veins are clustered in tens to

Genetic relationship between greisenization and Sn–W mineralization in vein and greisen deposits: Insights from the Panasqueira deposit (Portugal)

BSGF - Earth Sciences Bulletin, 2021
The W–Sn Panasqueira ore deposit is a magmatic-hydrothermal system, which includes a high-grade quartz-vein type mineralization and a disseminated greisen-type mineralization occurring in the upper part of the Panasqueira two-mica granite.
