前言秦岭横亘我国中部,从十九世纪七十年代以来,调查者甚多。中国地质学家对秦岭的地质调查,始于赵亚曾、黄汲清(1931)。他们对秦岭变质岩系的划分以、黄汲清关于秦岭地轴的论断,成为后来工作的基础。解放后,开展了系统的区域地质、矿产地质调查及专题研究,深化了对秦岭地质的认识;但是也提出了一些亟待解决的重要地质问题。陶湾群的层位及时代是其中之一。
Preface Qinling spans the central part of our country and there are many investigators since the 1870s. Geological survey of Qinling by Chinese geologists began with Zhao Yazeng and Huang Jiqing (1931). Their division of the Qinling metamorphic rocks, Huang Jiqing on the Qinling axis of judgment, has become the basis for later work. After the liberation, a systematic investigation of the geology and mineral geology of the area and its special studies were carried out to deepen the understanding of the Qinling Mountains geology. However, some important geological problems to be solved were also put forward. One of the layers and times of Tao Wan Group is one of them.
