The black carbonaceous slates, interbedded within the Proterozoic volcano-Sedimentary sequence of Cuddapah Supergroup in the vicinity of Mangampeta are found to the fullerene bearing and belonging to the shungite suite of rocks. Presence of fullerene in powdered rock samples is identified from the characteristic spectra obtained by laser desorption/Ionization spectrometry. This is further confirmed by making soxhlet extract using toluene and exposing it to different laser powers to avoid any possibility of it being analytical artifact. Both carbon allotrope fullerene C60 and C70 are identified within these rocks. Two geological samples collected from the prominent rock units within this thick sequence of black carbonaceous unit belonging to the shungite suite of rock are found to have fullerenes. This reporting of fullerene is first of its kind from any geological material from India. The only other occurrence of fullerenes in geological samples is recorded from the Shunga locality of the Karelean province of Russia.Keywords

The results of thirteenth international proficiency test (Geo PT 23) obtained at the geochemical laboratory of Geological Survey of India, Hyderabad are presented. Estimation of 34 trace elements including all the fourteen rare earths obtained by ICP-MS in Koln Loess sample (Loess- 1) is compared with the assigned values. Sample decomposition method and other relevant details of the analytical procedures adopted are presented. Depending up on the 'Z-scores' calculated, the fitness of the data for either "pure geochemistry" or "applied geochemistry" was assessed. An overview of 'Z- score' results indicates that all of the elements except barium of the data contributed from our laboratory fell with in the -2<2<2 range which included the majority of the trace and rare earth elements used normally in several pure geochemical investigations. The results have indicated that the data obtained at our laboratory is excellent and further allowed us to investigate the very minor analytical discrepancy observed in the barium data and optimize necessary aspects to rectify the bias.Keywords
