Abstract The northern Menderes metamorphic core complex has complex exhumation history and is one of the key localities to investigate the spatial and temporal relationships of extensional and compressional structures. Detachment faults and syn-extensional plutons are linked to a series of antiforms and synforms and the denudation of the northern Menderes Massif occurred in three stages. The first stage is related to the development of detachment faults under the consistent NE–SW-directed extension. The second stage is represented by a series of elongated magmatic domes that were oriented parallel, oblique and perpendicular to the regional extension direction. Emplacement of these asymmetrical magmatic domes appears to have been controlled by heterogeneous extension and post-dates the extensional Simav detachment fault. On the third stage, progressive heterogeneous extension that led to updoming of plutons has been finally accommodated by a localised and short-lived transfer zone, which was described as the Gerni shear zone for the first time in this study. The transfer zone is formed by a NE-striking, dextral ductile/brittle shear zone that accommodated the propagation of folds, conjugated strike-slip faults and normal- and oblique-slip faults. Mylonites associated with the transfer zone are related to the localisation of strain along the thermally weakened strike-slip fault systems by short-lived intrusions rather than to the development of regional-scale detachment faults. These structures are consistent with a transtensional simple shear model, which properly explains the evolution of extensional and compressional structures exposed in the northern Menderes core complex. Structural setting of the Eğrigöz region is somewhat similar to that of the NE-trending gneiss domes in the northern Menderes Massif and updoming of magma during late stages of detachment faulting appears to have played an important role in the exhumation of lower and upper plate rocks.

土耳其西部 Menderes 变质核复合体北部拉长岩浆穹窿和局部转移断层的伸展和横张成因

摘要 北部Menderes变质核杂岩体具有复杂的折返历史，是研究伸展和挤压构造时空关系的重点地点之一。拆离断层和同延岩体与一系列的反形体和同形体有关，Menderes 地块北部的剥蚀分三个阶段发生。第一阶段与在一致的 NE-SW 定向伸展下的拆离断层的发展有关。第二阶段以一系列与区域延伸方向平行、倾斜和垂直的细长岩浆穹窿为代表。这些不对称岩浆穹窿的侵位似乎是由异质伸展控制的，并且在伸展的 Simav 拆离断层之后。在第三阶段，导致岩体上升的渐进式非均质伸展最终被一个局部且短暂的转移带所容纳，该带在本研究中首次被描述为 Gerni 剪切带。转移带由一个 NE 走向的右旋韧性/脆性剪切带形成，该剪切带适应褶皱、共轭走滑断层以及正滑断层和斜滑断层的传播。与转移带相关的糜棱岩与沿热减弱的走滑断层系统的应变定位有关，而不是与区域尺度拆离断层的发展有关。这些结构与横张简单剪切模型一致，这恰当地解释了北 Menderes 核心复合体中暴露的拉伸和压缩结构的演变。
