The presence of polycyclic hydrocarbons, mono- and bicyclic alkanes, adamantine, diamantine, and methyldiamantanes in the K-P- boundary sediments at Kawaruppu has been reported [10]. Such poly hydrocarbons are also seen in the Anjar samples (figure.4)., which could be a precursor materials for the formation of fullerenes at the KPB. It is possible to suggest that the occurrence of fullerenes and an increase in carbon soot content are considered to be important geochemical markers of the KPB. The other carbonaceous matter, which are observed at the KPB sediments include polycyclic hydrocarbons , mono- and bicyclic alkanes and diamondiod hydrocarbons [10]. About 26 polycyclic aromatic hydrocarbons from naphthalene to coronene were reported from the KPB sediments at Kawaruppu, Hokkaido, Japan, indicating a possible combustion origin of these hydrocarbons within the KPB clays. The nanoparticles of primary iron minerals like hematite, goethite or limonite observed in KPB layer can also form in an impact event [6] . This fact, combined with the otherwise rare occurrence of these carbonaceous materials in nature, makes fullerenes potential geochemical markers for impact boundaries .In a nearby Meghalaya site, however Ni rich spinel has been found and therefore it is clear that impact metamorphism during KPB event has delivered its high-pressure products in the Indian subcontinent [3] . In conclusion, the systematic mineralogical investigations on the KPB section of the Deccan Trap revealed presence of the HPT phase of C 60 . The coexistence of high-pressure temperature (HPT) phase of C60 with high iridium concentrations at Anjar KPB makes it a good geochemical marker for the impact by the extraterrestrial material [11]
