净各留山一带,系指甘肃文县-四川南坪间白水江南侧的石炭系分布区。由于山大林密,地质工作程度低,以往多用未分石炭系表示之。1973-1975年,我队二分队在该区普查找矿过程中,获得较多地层资料,经整理,将中上石炭统初步进行划分与对比。目前,西北地层区划图所列秦岭文县-略阳小区地层表中所列石炭系剖面,为我队1974年度成果,很不完整,亦有错误,故以此文做补充。不妥处,请指正。
The net Gelushan area, refers to the Gansu Wenxian - Sichuan Nanping Whitewater south of the Carboniferous distribution area. Due to the great forest, geological work is low, in the past with no distinction between the Department of Carboniferous said. During 1973-1975, the second detachment of our team obtained more stratigraphic data during the census prospecting in the area. After sorting, the Upper-Middle Carboniferism was initially divided and compared. At present, the sequence of the Carboniferous section of the Qinling Wenxian-Lueyang Residential Area listed in the northwest stratum zoning map is the 1974 result of our team. It is incomplete and there are also mistakes. Therefore, this article is supplemented. Improper, please correct me.
