Mineral and fluid inclusions were studied in seven gem corundums from gravels of three areas in Sri Lanka. All fluid inclusions are pure CO2. Microthermometry results on primary fluid inclusions suggest formation of corundum under granulite facies me

The composition of chromites in Ni-arsenide-bearing chromitites and of orthopyroxenes in orthopyroxenites from several Cr-Ni-deposits in the Malaga peridotites, Spain, shows little variation in each deposit but strong variation between the deposits.
