In this study, FTIR and pyrolysis GC-MS analysis methods are used to characterize the handpicked solid bitumen (viscous residue of hydrocarbon) found as fillings in the lignite of Panandhro field, Gujarat. The FTIR data shows that solid bitumen is marked by intense aliphatic CHx stretching peaks between 3000 and 2800 cm-1, medium absorption of OH stretching, aromatic C=C, and aliphatic deformation peaks. A factor versus C factor plot indicates that it is mainly composed of type-II kerogen (organic matter). The pyrolysis GC-MS data shows the highly aliphatic nature of the solid bitumen. The overall characteristics indicate that the studied solid bitumen is of pre-oil generation type and formed from increase in thermal maturity of lignites.Keywords

The record of Cretaceous palaeo-wildfires is rather scarce for peninsular India. We aim to report a detailed macro-charcoal analysis as evidence for palaeo wildfires of Early Cretaceous deposits from India. The macro-charcoal was studied using SEM and classified into three morphotypes based on anatomical characteristics. All morphotypes are probably associated with gymnosperms. These findings constitute a record of macro-charcoal and consequently of palaeo-wildfires for the Lower Cretaceous strata of the Saurashtra Basin, Northwest IndiaKeywords
