- W2357961808 abstract "This paper is chiefly basing on the newly acquired data of the surface andsub-surface geology and of the geophysical survey to explain the following ques-tions: 1. The North China continental syncline is a lower Paleozoic depositionalplatform, on. which have been deposited the sediments of Sinian, Cambrian,Ordovician Carboniferous and Permian Ages. These sediments can well be corre-lated with those not exposed on the surface. 2. There are also the local existence of Mesozoic Basins in the North Chinacontinental syncline in a similar manner as those occurring along the outskirtsof the North China Plain. 3. The Variscian movement caused warping and folding of the North Chinacontinental syncline. The Yenshan and the Himalayan movements brought someof the fording features to trend in a northeast direction. 4. The principal tectonic movement is the uplift-sinking activities of thecrystalline basement. 5. During the Mosozoic and the early Cenozoic eras, this continental synclinewith its Paleozoic sediments was exposed as land and suffered erosion locally with some depositional depressions. Such a supposition tends to explain the greatunconformity surface now revealed between the overlying Cenozoic sediments andthe underlying Ordovician limestone. 6. During the end of Miocene or even a little earlier, the erosional surface ofthis contineatal syncline began to sink and separated itself from the continentalanticline, the Tahangshan. Thus this submerged portion is now covered by thePliocene and the Quartenary sediments. 7. There are three rather big depressions on this continental synclines. a. The Kaoyung Depression, area. about 20,000 km~2, the depositional areaunder a depth of 3,000 m is 4,200 km~2. The horizon of high electrical resistence(possibly the Ordovician and the Sinian beds) lies under a buried depth of 2,500to 3,000m. b. The. Lingching Depression, area about 12,000km~2, the. depositional areaunder a depth of 3,000 m is about 10,000 km~2. The horizon of high electrical resis-tence has a depth of 2,500--4,000 m. c.The Kaifeng Depression, area about 13,000 km~2. The horizon of high resis-tence has a depth of more than 3,000 m(?). The three depressions are now considered by the writer as oil-bearing." @default.
