Abstract:
Previously reported in the Mesozonic Tibet and the early Paleozoic Polar Ural,Russia , diamond and other deep minerals are found in ophiolite mantle peridotite chromite that need to be reconsidered ophiolite and chromite traditional understanding of the causes of shallow.The ophiolitic chromitite can be divided two classes, the high-Cr chromitite and high-Al chromitite.Most of the early studies of chromitites in China focused on high-Cr varieties, particularly in Tibet and the Polar Urals, leaving unanswered the question of whether such minerals also occur in high-Al varieties.In order determine whether high-Al chromitites also contain diamonds and to investigate the formation processes of the Hegenshan podiform chromitites, we carry out the mineralogy in chromitites of the Hegenshan ophiolite, Inner Mongolia, China.The Hegenshan ophiolite lies in the Inner Mongolia-Daxinganling orogenic belt, a part of the Central Asian orogenic belt, including both the Altaids and Manchurides Approximately 2000 kg of mainly disseminated chromitite ore were collected from orebody 3756.Minerals were separated at the Institute of Multipurpose Utilization of Mineral Resources, Zhengzhou, China and the samples were handpicked under a binocular microscope.Mineral identifications are based on optical properties and Raman spectroscopy.Preliminary studies have identified more than 30 mineral species in addition to diamonds and moissanite.The other minerals include oxides (mostlyKeywords:
