“略阳灰岩”为赵亚曾、黄汲清一九三一年所创,它位于略阳县城南灵岩寺一带,时代为早石炭世。由于该剖面未经详细研究,定义颇为含糊,名称甚多。随着石炭纪地层工作的广泛深入,有必要进一步明确其含义。最近在区域地层表中,用“略阳组”代表西秦岭南分区,相当于华南大塘期的一套以灰岩为主的沉积。净各留山的略阳组,为略阳灰岩的西延部分,同属一地层小区。我队在普查铝土矿过程中,获得较多的地层古生物资料,并首次发现大塘期早期的生物群,为在西秦岭有相当的旧司段沉积,提供可靠的依据。现将我队二分队多年的地质成果整理如后,不妥之处,请批评指正。
“Lueyang limestone” was created by Zhao Yazeng and Huang Jiqing in 1931. It is located in the area of Lingyan Temple in the south of Lueyang County. The era was Early Carboniferous. As the profile has not been studied in detail, the definition is rather vague and has many names. With the extensive and extensive work of the Carboniferous strata, it is necessary to further clarify its meaning. Recently, in the regional stratigraphic table, the “Lueyang Formation” represents the western Qinling South Division, which is equivalent to a limestone-dominated sedimentation in Datang Period of South China. Lvyang stay of the Lueyang Group, Lueyang limestone west extension part, belong to a stratiform plot. During the census of bauxite, our team got more information on the palaeontology and discovered the first biota in the Datang Period for the first time, which provided a reliable basis for the deposition of considerable old sections in the West Qinling Mountains. Now the second team of my team after finishing geological results for many years, inappropriate, please comment on criticism.
