在淮河上游幹支流發源地,伏牛山、嵩山、桐柏山一帶,有兩種不同體系的構造線存在着。按其生成時代的新老來劃分,一種可以北45°—60°西的構造線來代表,另一種則為近東西向的構造線。在淮河上游南灣、薄山、白沙等水庫的地質調查中,曾斷續地看到北45°—60°西方向的褶皺及衝斷層,也有同樣方
There are two kinds of tectonic lines of different systems existing in the origins of the tributaries of the upper reaches of the Huaihe River, the Funiu Mountain, the Songshan Mountain and the Tongbai Mountain. According to the generation of the old and new to their generation, one can be north 45 ° -60 ° west tectonic line to represent the other is the near east-west tectonic line. In the geological survey of the upper reaches of the Huaihe River in the South Bay, the thin mountain and the Baisha reservoir, the western side of the 45 ° -60 ° northwest fold and thrust fault have been intermittently seen,
