本文对浙江早、中侏罗世的生物地层作了全面、系统的研究。建立了新的地层单元——赤山坞组。并对早、中侏罗世地层的划分、对比和时代作了必要的修正。还提出了:(1)浙西早、中侏罗世的盆地有时迁现象;(2)浙西、浙东早、中侏罗世的植物群是属于两个不同的理区系地植物群;(3)浙东是由北方(华北板块分裂出来)漂移来拼接到华南大陆(华南板块)边缘的地体。江山—绍兴断裂之北被大片侏罗—白垩纪地层和早、中侏罗世地层覆盖的地区是寻找古生代油气藏的有利地区(带)。
This paper makes a comprehensive and systematic study of the early and middle Jurassic biostratigraphy in Zhejiang Province. Established a new unit of strata - red hill dock. And made the necessary amendments to the division, contrast and time of the Early and Middle Jurassic strata. It is also proposed that: (1) the early and middle Jurassic basins in western Zhejiang are sometimes migrated; (2) the flora of early western and eastern Zhejiang, early Jurassic and Middle Jurassic belong to two different flora groups ; (3) Zhedong is spliced to the edge of the South China mainland (South China Plate) by drifting northward (the North China plate splits out). Jiangshan - the north of the Shaoxing fault was covered by large tracts of Jurassic-Cretaceous strata and early and middle Jurassic strata that are favorable areas for finding Paleozoic oil and gas reservoirs.
