Abstract The occurrence of phlogopite and amphibole in mantle ultramafic rocks is widely accepted as the modal effect of metasomatism in the upper mantle. However, their simultaneous formation during metasomatic events and the related sub-solidus equ

A family of bimetallic complexes based on aurophilic interactions was synthesized, and tested for vapochromism and P–T variations. These complexes can originate cocrystals, opening the route to a new aurophilic-based crystal engineering.

The two most common polymorphs of MnO2, ramsdellite and pyrolusite, are often found in natural association. Our starting sample is from the Mistake mine (Arizona) containing macroscopic crystals of both ramsdellite (a = 4.5131(6), b = 9.2689(13), c =

The mechanical behavior of carbonate-bearing fluorapatite (CFAP) (with up to 5.5 wt% CO3) was investigated at high pressure up to 7 GPa. The incorporation of carbonate in CFAP samples was investigated by FTIR spectroscopy. The chemical formulae and c

The structural behaviour of cassiterite (SnO2), pyrolusite (MnO2) and sellaite (MgF2), i.e. AX2-minerals, has been investigated at room temperature by in situ high-pressure single-crystal diffraction, up to 14 GPa, using a diamond anvil cell. Such mi

In situ high-pressure X-ray diffraction study was performed on synthetic lead feldspar with composition PbAl 2 Si 2 O 8 (PbFsp). The crystals were synthesized from the melt and thermally treated at T = 1150 °C for 12 h and at T = 1000 °C for 70 h.
In situ high-pressure X-ray diffraction study was performed on celsian (Cls97Or3) from Jakobsberg, Sweden. A single crystal of celsian was loaded in an ETH-type diamond anvil cell, and unit-cell parameters were measured at 20 different pressures up t

The volume and unit-cell parameters of analbite (i.e., NaAlSi 3 O 8 with complete Al,Si disorder) have been determined by single-crystal X-ray diffraction to a maximum pressure of ~8.71 GPa. The volume variation with pressure is described by a fourth

A natural sample of anorthoclase of composition Na 0.63 K 0.27 Ca 0.10 Al 1.10 Si 2.90 O 8 (Ab 63 Or 27 An 10 ) was treated at T = 950°C for one week, and then investigated by single-crystal X-ray diffraction in situ at high pressure using a diamond
