浅析肃北县德勒诺尔铁矿区的构造特征

摘要

It is considered that there are three periods of stress effect in Delenuoer iron deposit about the study of the structural system. The first period that NS stress caused by the EW tectonic. The second period that NE-SW stress caused by the NW tectonics, third period that EW 1 stress for the relaxation of the tension caused by a series of tensile structure.%德勒诺尔铁矿受祁连山长期造山运动影响,使区内构造错综复杂。德勒诺尔铁矿区构造分为SN向挤压应力作用下形成的近EW向构造;NE—SW南西向挤压应力作用下产生的NW向构造;EW向应力松弛拉张作用下形成的一系列张性构造。通过对肃北德勒诺尔铁矿构造特征研究,以期对该矿区后期找矿工作提供重要依据。
