秦岭在我国是一条年代比较古老的山脉,同时也是一条年代比较新的山脉;所谓古老是从地质方面来说,所谓新是从地貌方面来说。北秦岭虽然有人称其为加里东地槽,但多数对秦岭有研究的学者仍称其为地轴; 秦岭中南部的地质,学者间的意见比较一致,大都认为南秦岭的南部是加里东期地槽,南秦岭的北部是华力西期的地槽,南秦岭的中部是印支期地槽,总之整个秦岭都是中生代下部及其以前的产物;有的学者认为秦岭地轴的中心部分及狭义的地轴部分是元古代地槽的中央隆起,远在元古代地槽的初期即已存在,称其为太古代秦岭地轴;因此说秦岭是一条年代比较古老的山脉。
Qinling Mountains in our country is a relatively old mountain, but also a relatively new era of mountains; the so-called ancient is from the geological aspects, the so-called new is from the aspect of the landscape. Although some people call it the North Caledonian Gallstone groove, but most of the Qinling scholars still call it the ground axis; Qinling Mountains in central South China, the views of scholars more consistent, most of the South that the South Qinling Caledonian The northern part of the South Qinling Mountains is the Gorge of the Waxing Period. The middle part of the South Qinling Mountains is the Indosinian Gully. In conclusion, the entire Qinling Mountains are the Lower Mesozoic and its former products. Some scholars think that the central portion of the Qinling axis and its narrow sense Part of the epicenter is part of the Proterozoic to the central uplift of the trench, far in the early Proterozoic that has existed before the trench, called it the Pacific Qinling axis; so that Qinling is a relatively old mountain range.
