The internal textures of crystals of moderately radiation-damaged monazite–(Ce) from Moss, Norway, indicate heavy, secondary chemical alteration. In fact, the cm-sized specimens are no longer mono-mineral monazite but rather a composite consisting

Olenitic tourmaline with high amounts of tetrahedral B (up to 2.53 [4] B pfu) has been synthesized in a piston-cylinder press at 4.0 GPa, 700 °C, and a run duration of 9 days. Crystals are large enough (up to 30 × 150 μm) to allow for reliable and

Majoritic garnet, characterized by an excess of silicon (>3 Si per formula unit), is considered one of the major phases of the Earth’s transition zone from 410–660 km depth. Quantifying the H2O content of nominally anhydrous mantle minerals is ne

Pseudotachylytes, coseismic frictional melts, have formed in metagabbro and within a kinzigitic shear zone of the Ivrea Zone (Italy). In both rock types, amoeboid garnet has crystallized in the pseudotachylyte matrix, locally as a rim overgrown on pr
