摘　　要：冀东马兰峪混合杂岩区ＮＮＥ向延伸的线性构造非常发育，线性构造的形成是由于在晚太古代末期的造山运动使本区岩石受到强烈的构造置换作用、岩浆侵入作用和深变质作用的结果。NNE-trending linear features were well-developed in Malanyu mixedcomplex in East Hubei Province。It was formed as a result of the rockbeing subjected intensively by the tectonic emplacement , magmaticintrusion and deep metamorphisim in this area during the orogenic movementof late stage of later Archean era。
