浙江象山县石浦镇附近出露的石灰岩时代,主要有三种意见:1.石炭二叠纪飞来峰矽质燧石灰岩(张秀峰1957);2.上古生界(中国地质科学院地质矿产研究所,浙江省区域地层表编写组1976);3.中生界下白垩统朝川组(浙江省区测队1973)和馆头组(浙江省石油地质大队1980)。1979年3月,作者等实测石浦平岩村—沙塘湾村剖面时,发现许多管状化石和叠层石,经鉴定,管状化石为龙介科Serpalidae虫管。本剖面层序清楚,沉积物为碎屑岩夹碳酸盐岩,岩石虽已变质,但保存完好的复理式建造特征。鉴于其沉积
There are three main opinions on the limestone age exposed near Shipu Town, Xiangshan County, Zhejiang Province: 1. Carboniferous Permian Filaifeng Siliceous Flint Limestone (Zhang Xiufeng 1957); 2. Upper Paleozoic (Institute of Geology and Mineral Resources, Chinese Academy of Geological Sciences, Zhejiang Formation Formation Group 1976); 3. Lower Cretaceous Chaochuan Formation of the Mesozoic (Zhejiang Province Survey Team 1973) and Guantou Formation (Zhejiang Petroleum Geological Brigade 1980). In March 1979, when the authors actually measured the section of Pingyan Village-Shantangwan Village in Shipu, many tubular fossils and strata were found. The fossil was identified as Serpalidae. The sequence of this section is clear. The sediments are clastic-clastic carbonate rocks. Although the rocks have been metamorphosed, they are well-preserved, complex-type structures. Given its deposition
