Research

My research centers on the mineral diamond; in particular the syngenetic mineral inclusion content and the physical and chemical characteristics of the host. When the geochemistry of the inclusions is combined with the physical characteristics of the diamond, detailed information is obtained about the different environments of diamond formation in both the upper and, more recently, the lower mantle. From inclusions, both the genesis and eruption ages of diamond can be determined. Sulfide inclusions specifically, can tell us about the early Earth atmosphere, (see Publication list). Crustal and mantle processes are linked through the possible involvement of crustal carbon and nitrogen in subduction mechanisms leading to the formation of eclogitic diamonds at depth. In this regard, the isotopic signatures of such diamonds are assessed against crustal values.
