Late Carboniferous–early Permian sediments belonging to the Haushi Group in Oman have been considered to be partly of glacial origin1–3. However, conclusive evidence of a continental glaciation has been lacking, and the extension of the late Palaeozoic Gondwana glaciation into the Arabian Peninsula has not been generally accepted4. During recent visits to outcrops of the Haushi Group in the Al Khlata area of the Huqf Massif (Fig. 1), we have found good exposures of striated pavements of Precambrian dolomite, which are directly overlain by diamictites of the Haushi Group (Fig. 2). This occurrence forms the strongest evidence so far for the presence of a continental glaciation in Oman during the late Palaeozoic.
