Isolated olistoliths from the Lower Triassic Xikou Formation in southwestern Fejian and its geological significance

摘要

ISOLATED olistoliths refer to massive blocks of rock occurring out of place, but with sedimentary contact relationship, within unrelated sediments. They were transported as single masses into the basins in which they occurred. In this note we will first report examples found from the Lower Triassic Xikou Formation in southwestern Fujian and discuss its geological significance.
