  • The diamond ore occurring in the alkali-basic rocks in Langan area,Anhui Province,which is located in the west side of Tanlu(Tancheng-Lujiang)fault zone.Special care is taken to prevent cross contamination of synthetic diamonds used in the normal drill bits by using a special alloy drill bit.Diamonds are yellow-brownish or yellow colour,transparent,with adamantine luster.These diamonds mainly showed combined growth habit of cube and dodecahedron,a few of cube and octahedron,and a few of octahedron and dodecahedron.The size distribution is 0.5-0.6mm.Laser Raman spectroscopy showed the typical diamond peak at 1 332cm-1.The host rocks(dolerite)of these diamonds were formed in a tectonic setting of intraplate,with the characteristics of enrichment in LILE(K,Rb,Sr,Th and Ba),and depletion in HFSE(Nb,Ta,Zr and Hf).The REE features demonstrated the rocks coming from the deep mantle,and undergoing low-degree partial melting of peridotite before emplacement.The obvious Eu negative anomaly indicated the magma was clearly fractionated by crystallization of plagioclases.Based on these geochemical observations,we believe that these alkali-basic rocks in the Langan area may have the possibility of the diamond ore formation.
