The Archaean craton in southern West Greenland comprises numerous occurrences of ultramafic alkaline rocks including kimberlite (senso lato), ultramafic lamphrophyre, lamproite and carbonatite. The kimberlite research group at GEUS has since 2001 been concerned with the task of studying known and tracing new occurrences using geochemical and geophysical tools. A study of geochemical and geophysical surface signatures of these rocks has been successful and resulted in many new occurrences. The work conducted by the research group includes storing and systematising information and data reported by exploration companies and field data obtained by GEUS. In addition, the data is used to study the origin of the alkaline magmas, and to assess the diamond potential of West Greenland. Presently,the origin of the alkaline magmas is addressed by mineral chemistry and melt characterisation. A significant diamond potential has been established for southern West Greenland based on the physical regime in the lithospheric mantle and by indicator mineral chemistry.
