Study on Base Level Cycle and Coal Formation in Coal-bearing Strata in Heze Area
摘要
Abstract
By using multidisciplinary combination of stratigraphy,sedimentology and coal geology,base level cycle division has been carried out in late Paleozoic Carboniferous-Permian high resolution sequence stratigraphy in Heze area.Through analysis on variation characteristics of base level cycle,the coupling mechanism with the effects of the coal has been studied.It is found that the sedimentary deposits in Heze area can be divided into 2 super long period,5l ong period,12 medium period and 30 short period base level cycles.Comparing high resolution sequence stratigraphy in coal-bearing areas in Heze city,the function relationship between base level cycle and coal has been summarized.It is found that No.17 and No.18 coal layer in the LSC1 cycle were mainly formed in the barrier coast environment in rapidly rising period to slow down period.The coal would be formed after the water retreated.No.16 coal layer in LSC2 cycle was formed in the tidal flat environment in rapid rising period.The coal was formed by transgression events. No.3 coal layer in LSC3 cycle was formed in the shallow water delta environment in the epicontinental sea in rapid rising sea period to slowing up and then to slowing down period.The coal was formed by typical delta regression.关键词
