| 摘 要： | 华北台地南缘安徽淮南、霍邱地区早寒武世早期地层较发育．从岩性、沉积相、层序地层上均反映自西往东变化较大，表现为由深变浅的深切谷充填型沉积。它表明这一期间．华北板块与扬子板块之间碰撞挤压已经结束．转化为拉张性质的运动。

| Abstract: | In the Huainan and Huoqiu area of Anhui of the southern margin of North China Plauorm,the strata of the early stage of Early Cambrian Epoch are relatively developed and considerable changes shown in lithology,Sedimentary facies and stratigraphic sequence from west to east as a suite of deep dissected valley filling-type deposits from deep to shallow.It indicates that the collision and compression between the North China Plate and Yangtze Plate ended and turned into extensional movement in this period. |
