闽西南马坑式铁矿的层位和时代,以往因缺乏化石证据,意见不一。有中石炭统下部、下中石炭统或石炭二叠系种种说法。 1978年,我们在上杭县湖洋矿区的毗邻处庐丰发现了颇为完整的石炭系剖面,岩层中含有丰富的化石,保存尚佳。本文是在系统测制地层剖面及研究其中所含动植物化石的基础上,结合这几年来我系师生在长汀、永安等地区收集的资料写成的。 The levels and times of the Makeng-type iron mines in the southwest Fujian have different opinions in the past due to the lack of fossil evidence. Lower Carboniferous, the Lower Carboniferous or Carboniferous Permian all kinds of claims. In 1978, we found a quite complete Carboniferous section in Lufeng, adjacent to the lake ocean mining area in Shanghang County. The rock layers are rich in fossils and are preserved well. Based on the systematic measurement of the stratigraphic profile and the study of the fauna and flora fossils contained therein, this article is based on the data collected by teachers and students in Changting and Yong’an in the past few years.
