The miliolite limestone of Kachchh and Saurashtra areas of the Gujarat state, western India is a unique sedimentary sequence of the Middle to Late Pleistocene age that has been studied mainly for its relationship with sea level changes and local tectonics. In Kachchh the Katrol Hill Fault (KHF) is considered as an active fault characterized by earthquake occurrences. The occurrence of fibrous form of calcite in miliolite limestone of the Gangeswar area in Katrol Hill Range (KHR) has been described in this study using thin section and SEM-EDS, and considered as manifestation of active tectonics during the deposition and diagenesis of the miliolite limestone in the study area as its morphogenesis is linked with elevated radon in moist environment. Thus, the study provides a new tool to assess the earthquake prone areas. Keywords: Lublinite, Radon, Miliolite, Neotectonics, KHF, Kachchh.Abstract
