苏北地区上前寒武系发育一套厚约五千米以上以海相为主的未变质地层。由于其岩性和生物组合的特殊性及其所处地理和构造位置的重要性,被视为解决我国南北方上前寒武系衔接和对比的关键地区之一。近年来,本区上前寒武系在生物地层、岩石地层、同位素地质等方面已经取得了一些重要成果,但对它们在我国上前寒武系所处的位置仍持有不同意见。至今,尚未见到有关的古地磁文章发表。 Precambrian in northern Jiangsu developed a set of about five thousand meters thick to marine-based non-metamorphic strata. It is considered as one of the key areas to solve the convergence and contrast of the Precambrian systems in the north and south of our country due to the particularity of its lithology and biological assemblage and its geographical and tectonic positions. In recent years, some important achievements have been made in the areas of biostratigraphy, lithostratigraphy and isotopic geology in this region, but there are still different opinions on the location of the Precambrian in China. To date, no relevant paleomagnetic articles have been published.
