在前人定为“层状堆积杂岩体的辉长岩单元”中发现了一套副变质中－基性麻粒岩。它与正变质的基性麻粒岩成互层产出，二者又与层状变质橄榄岩共同组成了一个并非原生火成堆积岩的层状杂岩体。介绍了这套副变质麻粒岩的出露“层”序、主要岩石类型、原岩建造。认为其原岩是一套主要来源于洋盆内基性火山碎屑的深水沉积岩，其中碎屑锆石Ｕ－Ｐｂ年龄为４２１Ｍａ。这套岩石曾于中石炭世俯冲至中天山－哈萨克斯坦板块之下，同时遭受到麻粒岩相区域变质改造（３１５Ｍａ）；其后，又以高温韧性剪切方式，快速逆冲至南天山早古生代非岩浆型被动陆缘带中。
In the predecessor of “layered sedimentary complex gabbro unit” found in a set of metamorphic - basic granulite. It is interbedded with the metamorphic basement granulite, which in turn forms with the layered metamorphic peridotite a layered complex that is not a native pyroclastic accumulation. The outcropping “sequence” of the paramorphic granulite is introduced, the main rock type and the original rock are built. It is considered that the original rock is a set of deep-water sedimentary rocks mainly derived from the basic volcanic clasts in the ocean basin, in which the detrital zircon U-Pb age is 421Ma. This rock was subducted to the Middle Tianshan-Kazakhstan Plateau in the Middle Carboniferous and suffered metamorphic remnants of granulite and lithofacies at the same time (315 Ma). Later, it was rapidly sheared to the South Tianshan Early Paleozoic non-magmatic passive continental margin.
