苏北滨海地区早石炭世孢子的发现

THE DISCOVERY OF LOWER CARBONIFEROUS MIOSPORES ASSEMBLAGES OF FROM A BOREHOLE IN THE BINHAI DISTRICT, NORTH JIANGSU

作者首次在苏北滨海地区滨 - 2井中发现了早石炭世的蕨类植物孢子 ,共 38属 6 1种 ,组成 Aurorasporamacra- Schopfites claviger(MC)组合 ,经研究属早石炭早期 (Tn1 b上部— Tn3)。从而补充了整个江苏地区的早石炭世孢子组合序列 ,并与苏南龙潭、句容、苏中的宝应以及国外相应的地层进行了简要对比。为该地区的能源勘探提供了新的地层依据。

This paper is the first research of miospores from the Lower Carboniferous of a borehole Bin Ⅱ 2 in the Binhai district, North Jiangsu. The present paper records and illustrates 61 species assigned to 38 genera,characterized by Auroraspora macra Schopfites claviger (MC) assemblage. Depending on the analysis of the miospores, the assemblage zone is considered to belong to the Early Tournaisian (late Tn 1b—Tn 3) and can be correlated with the known palynological zones from Longtan, Jurong in southern and Baoying in central Jiangsu Province and the equivalen zones from other countries. This study makes the miospore aseemblage succession of the Lower Carboniferous more continuous from Jiangsu Province and will help to the exploration of resources in this area.
