Abstract: The Mantou Format ion in the North China platform, which overlain the Archaean Taishan Group, mainly consists of terrigenous clastic rocks and carbonate interca lations. In the Zhonggong village of the Jinan city, olistotrome with thickness of about 4m occurred in the lower part of the Mantou Formation. Carbonate and fine clastic rocks is its block, and siltstone is its matrix. Deformation styles of the blocks and cross bedding within the blocks demonstrate that there should ex ist an old slope in the North China platform and tectonic uplifting had took place in the Cambrain. They were main factors to induce olistotrome. Identifying and studying the olistostrome with in the Mantou Formation is benefit to study the Paleozoic paleogeography and sedimentary env ironments of the North China platform and the evolution of the buried hills, which can provide some good evidences for the study on the Paleozoic sedimentary basin contained with abundant oil and gas and buried hills, and for prospecting source of oil and gas.
