秦岭地处我国南北两大不同构造单元衔接地带。长期以来是地学界十分瞩目的地区。区内地质构造复杂,岩石多已变质,基础地质方面存在着不少“老大难”问题。近年来笔者在区调工作中取得了一些新的进展和认识。主要有:(1)首次在卢氏官坡、兰草一带被前人划归为下元古界“陶湾组”的地层中,采获了古生代动物化石,时代可能为志留纪。(2)发现前人原划分的下元古界“下宽坪组(即二郎坪群)”与宽坪群並非一套地层,属早古生代产物。(3)前人在西峡地区原划分的一部分“宽坪群”(即小寨组、抱树坪组)与卢氏魏王坪一带的上三迭统可能同属一套地层。(4)安坪—丹矾窑断陷带是个长期未引起人们重视的十分独特的地质构造单元。过些问题关系重大,有必要提出讨论,以期引起重视。 Qinling Mountains is located in our country two major tectonic units convergence zone. It has long been a place of great interest to the academic community. The geological structure in the area is complicated, the rocks are mostly metamorphosed, and there are many “unsolved” problems in the basic geology. In recent years, I made some new progress and understanding in the area adjustment work. Mainly: (1) for the first time in Luan Guanpo, Lancao area was formerly classified as the Lower Proterozoic “Tao Bay Formation” of the strata, the acquisition of the Paleozoic animal fossils, the era may be Silurian. (2) The Lower Proterozoic “Xiakongping Formation (ie Erlangping Group)”, which was previously divided by the predecessors, is not a set of strata that belongs to the Early Paleozoic. (3) The predecessors in the former part of the Xixia area “Kuan Ping Group” (ie, Xiaozha Formation and Shupingping Formation) and the Upper Third Triassic of Lushi Wei Wangping may belong to the same set of strata. (4) Anping - Dan alum kiln fault zone is a long-term has not attracted much attention of the very unique geological structure unit. Some issues are of great importance and we should discuss them in order to attract more attention.
