摘    要:漠河逆冲推覆构造发育在上黑龙江盆地的西北侧,是漠河地区的主要构造样式。逆冲推覆构造在空间上由一系列规模大小不等、近平行排列的逆冲断层构成,剖面上表现为犁式逆冲断裂所构成的单冲式叠瓦状构造。按其岩石组合、变形变质特征和推覆体不同可划分为4条构造分带。推覆方向总体由NW向SE,具有前展式的扩展方式,运移距离大于4 km,形成于晚侏罗世中期—早白垩世中期。并在较为系统研究漠河逆冲推覆构造特征的基础上,探讨了其生成演化的过程。

关 键 词:逆冲推覆构造  生成演化  上黑龙江盆地  漠河  大兴安岭

Abstract:The Mohe thrusting tectonics is developed on the north-western of the upper Heilongjiang Basin,it is the main structural styles in Mohe region.The thrusting tectonics is composed of a series of the scale size is different and nearly parallel thrust like plough shape in across section,profile performance for the plow-thrusts posed by the single-chong imbricated structures.According to lithology,metamorphism and deformation characteristics of different nappe can be divided into six sub-tectonic belt.The thrust is from NW to SE in overall direction and the extension pattern of the thrust is pickaback and the slipping distance is more than 4 km,occurred during between the middle period of the Late Jurassic and Early Cretaceous.Studies counter in the system flushes pushes covers the structure characteristic in the foundation,has discussed the process which itsproduction evolves.
Keywords:thrust nappe structure  production evolution  upper Heilongjiang Basin  Mohe  Daxing'-anling
