Formation of fluid inclusions and etch tunnels in olivine at high pressure

Tubes, 3-10 mu m in diameter and up to 3 mm long, and linear arrays of spherical and crystallographically faceted fluid inclusions, 5-35 mu m in diameter, were produced in single crystals of San Carlos olivine (Fo89) annealed in the presence of CO2 and CO2-H2O fluids at 2-3 GPa and 1200-1400 degrees...

Zusammenfassung:	Tubes, 3-10 mu m in diameter and up to 3 mm long, and linear arrays of spherical and crystallographically faceted fluid inclusions, 5-35 mu m in diameter, were produced in single crystals of San Carlos olivine (Fo89) annealed in the presence of CO2 and CO2-H2O fluids at 2-3 GPa and 1200-1400 degrees C in a piston-cylinder apparatus utilizing NaCl-BN sample assemblies.
