| Abstract: | In the Early Paleozoic, Ordos massif evolved into cratonic carbonate plateform which underwent three stages of plateform evolution: clastic-carbonate plateform stage from Cambrian to Early Ordovician, evaporite plateform stage during Majiagou period of Middle Ordovician and drowned and foundered plateform stage from Pingliang period of middle Ordovician to Beiguoshan period of Late Ordovician. Based on the study of tectonic subsidence history, thermal decay was perhaps the primary mechanism controlling development of clastic-carbonate plateform from Cambrian to Early Ordovician. During Majiagou period of Middle Ordovician, tectonic subsidence apparently was driven primarily by loading and compression of the lithosphere, led to subsidence differential and. to form arch and sag in the massif. For the remainder time of Ordovician, continuous compression led to elevation of the massif in the large area. |
