意大利北方伊夫雷亚带的瓦莱德奥索拉地区的高温断层带似乎适应了地壳深部部分的延伸。~(40)Ar-~(39)Ar年龄谱表明,该伸展事件发生在280 Ma之前,并开启了一个地壳减薄冷却期。在该系统中,闭合温度的解释取决于晶粒尺寸和冷却速率。
Summary High temperature fault zones in the Valle d’Ossola region of the Ivrea zone in northern Italy appear to accommodate extension of the deep crustal section. 40Ar-39Ar age spectra indicate that this extensional event occurred prior to 280 Ma, and initiated a period of crustal thinning and cooling. Interpretation of the closure temperature in this system is dependent on grain size and cooling rate.
