Research on Ecostratigraphy of Changhsingian at Meishan Section D, Changxing, Zhejiang Province

摘要

On the basis of researches over several years on biostratigraphy of Changhsingian at Meishan Section D in Changxing County, the abundant materials were accumulated. This paper studies the ecostratigraphy and establishes 7 community zones (CZ), in ascending order, Sinoplatysomus―Geinitzina―Clarkina sub-carinata, Tapashanites―Nodosaria―Clarkina subcarinata, Crurithyris―Geinitzina―Clarkina subcarina-ta, Glomospira―Clarkina changxingensis, Colaniella―Clarkina changxingensis, Rotodiscoceras―Palaeo-fusulina―Hindepdus typicalis, Clarkina meishanensis―Hypophiceras. The habitat type (HT) is different from upper shallow sea to the lower part of the lower shallow sea.
