The presence of authigenic clay minerals is usually found in sandstones where these minerals grow in the environment itself. Authigenic clay minerals provide benefits to sandstones, especially to determine the quality of porosity and permeability in sandstones. The samples in this study were collected from an outcrop of measured section at Cipamingkis’ River. The main goal of this study was to understand the presence of authigenic clay minerals in sandstones caused by the diagenetic process using Scanning Electron Microscope and Energy Dispersive X-Ray (SEM – EDX method. The results of this study were kaolinite, smectite, and illite found in very dominant amounts in sandstones as pore linings, pore fillings, replacement, and vug fillings.
