Opinions vary on the genesis of this type of gold deposits. On the basis of observation and study in this area, with information up to date from other researchers, the authors bring forward that the formation of Muruntau-type of gold deposits in South Tianshan area is closely related to giant nappe structures, especially to the ductile shear zone.

关於该类金矿床的成因也是众说纷纭，根据作者近几年在南天山地区的调研得到的一些认识，以及其他学者对该地区穆龙套型金矿床的最新研究成果，认为南天山地区穆龙套型金矿床的形成与南天山褶皱造山带形成过程中板块边缘的大型逆冲推覆构造，特别是与其伴随的韧性剪切变质变形带具有密切的关系，而与这些构造作用伴随的花岗质岩浆的侵入作用是形成该类金矿床的必要条件。
