浙江侏罗—白垩纪的地层系统,是以浙东的永康盆地和浙西的寿昌盆地为基础建立起来的。而这两个盆地的地层对比(主要是寿昌组与馆头组能否对比),随着丽水老竹盆地地层的深入研究而基本得到解决。现将老竹盆地下桥的地层剖面介绍如下: 上覆地层:永康群朝川组:暗紫红色粉砂质泥岩夹砂岩和砂砾岩。

Relative positions of the Shouchang Hengshan and Guantou Formations are discussed on the basis of Laozhu section(Lishui countr)combined with some regional data available。 The mafn conclusions are follows: 1.The Hengshan Formation should be underlain the Guantou Formation but overlain the Shouchang Formation. 2.The boundary between Jurassic and Cretaceous continental sediments in Zhejiang should lie between the shouchang and Hengshan Formation.
