The Evolution Of The Lithofacies Palaeogeographic During Late Paleozoic In The Western Of Shandong, Eastern China

In order to reveal the evolution of the lithofacies-palaeogeograph- ic in the Western of Shandong Province, this paper presents the re-sults of a detailed study using of multiple disciplines, such as Sed- imentology, Sequence Stratigraphy and Paleogeography. The focus is on the coal -bearing stratum of the lithofacies paleogeographic in the Western of Shandong Province. The investigation indicates that: the platform-lagoon facies developed during Benxi period in the Per- mo-Carboniferous, areas have barrier island and peat flat depositional environment; The Taiyuan period mainly formed in a tide flat-lagoon depositional environment, ephemeral barrier islands. During Shanxi period there was development of delta plain-delta front depositional environment in a lagoon-tidal flat setting. Beach facies and flood ba sin facies developed in Shihezi–Heishan period, having shallow lakes in between. During Wanshan period the setting changed into alluvial plain river-lake environment. Through the analysis of the late Paleozo- ic lithofacies-paleogeography in the western Shandong, an important guiding bearing may emerge in resources exploration.
