The area in the west of Daxingxi structure to Mingshan syncline hasn't been explored and drilled yet.大兴西构造以西至名山向斜。
But the dip angles of both limbs of the syncline look different, with one limb steeper than the other though they dip toward the opposite direction.但是这个向斜构造的两翼岩层倾角看起来有差异，虽然两翼的岩层倾向相反，其中一翼倾角较之于另一翼要陡一些。
