The Nejdek Pluton, including the late highly fractionated Podlesí stock, is the most typical example of a strongly peraluminous rare...

..., titanite from the Mt. Lindsay Sn-W skarn contains up to 1300 ppm WO 3 ( Kwak 1983 ) and titanite from the Qitianling Sn-bearing granite contains up to 26 wt.% SnO 2 ( Xie et al. 2010 ), which is not surprising considering that there is a complete solid solution between titanite and malayaite...

In the Notch Peak intrusion, magmatic titanite grains usually have oscillatory zones combined with BSE-bright sector zones, in some cases surrounding simple unzoned cores. These grains are frequently overprinted by hydrothermal titanite...

... from the La Obra–Cerro Blanco intrusive suite, which allows us to explore the petrogenesis and magma emplacement processes in the upper crust. This intrusive suite is composed of (1) a vertically zoned granitoid intrusion in spatial association with mafic layers and stocks and (2) a cupola-like high...

Tourmaline is associated with greisens, breccias, and veins, which occur around the Triassic Chacaltaya peraluminous granitic stock hosted by Silurian metasedimentary rocks. Three main petrographic types of hydrothermal tourmaline have been identified: pre-ore...
