Abstract:

楼子店变质核杂岩以拆离系中韧性剪切与脆性拆离运动学不一致,有别于北美科迪勒拉变质核杂岩。构造分析表明,核杂岩两侧拆离系中韧性剪切具有统一的上盘向北东的剪切特征。采自核杂岩两侧韧性剪切带中的3个黑云母单矿物^40Ar/^39Ar年龄介于126~128Ma之间,西侧韧性剪切带中1个角闪石单矿物^40Ar/^39Ar年龄为134Ma,4个样品的坪年龄与对应的等时线年龄一致。角闪石和黑云母坪年龄记录的韧性剪切作用的时限为126~134Ma,并且显示出韧性伸展的特点。研究表明楼子店变质核杂岩两侧的韧性剪切带形成时间一致并具有相同的运动学,韧性剪切作用是核杂岩形成演化的一个重要阶段,这为核杂岩形成的韧性伸展阶段的约束提供了年代学证据。
