| 摘 要： | 豫南、皖西晚期中生代地层可以划分为上侏罗统、下白垩统及上白垩统。属于晚侏罗世的有毛坦厂组、黑石渡组、南召组及西谭楼组下段。白湾组下段可能也应归于此期。下白垩统是这一地区的主要沉积层,有晓天组、锦湾组、西谭楼组上段、马市坪组及白湾组上段。上白垩统则分布零星。该地区有发育较好的侏罗系-白垩系剖面,对它们的研究必将为解决侏罗纪、白垩纪的界线提供重要的证据。

| Abstract: | Thc late mesozic in southcrn henan and western anhui can be divided into upper jurassic,lower cretaccous and upper crctaccous.Motanchang F.,Hcishidu F.,Nanzhao F.and Lower part of Xitanlou F.are upper jurassic.Lower cretaccous is thc main sediments of those arcas.Upper part of Baiwan F.,Mashiping F.,Upper part of Xitanlou F.,Xiaotian F.are this period.The upper cretaccous in those areas is fragmentary in distribution.There are well developed scetions of Jurassic and cretaccous in southern henan and western anhui,they will give some cvidences for studying boundary between jurassic and cretaccous. |
