Shale samples from Kubang Pasu (KP) Formation has been taken from two small hills in the Beseri area of Perlis: Bukit Chondong and Kampung Guar Jentik, Kedah, and accounted for spectroscopic and petrographic characterization during this study to provide an opportunity to explore the organic matter quality and quantity, hydrocarbon bonds distribution and texture and structure characteristics present in these shale. Determining these properties of KP will help establish relationships between the total organic carbon (TOC) with humic acid. This is achieved by determining the organic carbon content and humic spectroscopic UV-visible ratio (E4/E6). The calculated UV-visible ratios of E4/E6 for both outcrops indicate the dominance of humic acids over fulvic acids indicating a strong possibility of terrestrial origin. The attenuated total reflectance (ATR) fourier transform infrared spectroscopy (FTIR) was used in the assessment of hydrocarbon present in rocks. Analysis with the ATR-FTIR shows that the aromatic OPCH stretching (690-900 cm-1) hydrocarbon and aromatic IPCH stretching (600-700 cm-1) hydrocarbon groups (both occur in the finger print region) absorbance are more in KP Formation as compare to other hydrocarbon bands. OH groups stretching vibration, alkyne C-H bending bands and alkane C-H bending band in aliphatic hydrocarbons and absorption spectrum of aromatic C=C stretching and aromatic OPCH are found in the FTIR spectra of KP shales. The petrographic analysis results show that KP shale samples consist mainly of dark to light grey, silty, micaceous, massive, discontinuous wavy parallel laminated, brownish massive, parallel laminated and non-calcareous mudstone. © 2018.
