    Abstract

    large siliceous sedimentary block was exposed in the vicinity Pos Blau, Ulu Kelantan. The block is a part of mélange in the Bentong-Raub Suture Zone. The lower part of the block is composed of ribbon chert and the upper part consists of interbedded siliceous mudstone and tuffaceous mudstone. Five samples from the siliceous mudstone yielded very low number of individuals but fairly high number of species. Fourteen radiolarians taxa were identified. The radiolarians are divided into two assemblage zones namely Pseudoalbaillella fusiformis Zone and Follicucullus monacanthus Zone indicating Middle Permian age. The occurrence of tuffaceous material in Middle Permian siliceous rock in Peninsular Malaysia was related to volcanic activities as a result of collision between Palaeo-Tethys oceanic crust and the East Malaya terrane. The source of the tuffaceous material was from the East Malaya terrane. The tuffaceous sediments became widespread in Late Permian and Triassic. This indicates the early stage of closing the Palaeo-Tethys.
