Abstract

Beranoaguirre et al. (Int J Earth Sci 108:2037–2046, 2019) have added a valuable piece of information to the Carboniferous tectono-thermal record of Europe by documenting a short-term pulse of heating in high-pressure metamorphic rocks of the NW-Iberian allochthons (c. 350 Ma, Malpica–Tui unit). They correctly state that the short duration of the thermal event is untypical of orogenic subduction/collision processes, but still envisage short-time heating within the subduction channel. The present comment is intended to point out that short-term thermal events of similar age are widespread in Europe and are part of a polyphase metamorphic history controlled by episodic heating from the mantle, probably over the plume-generation zone TUZO.

摘要

Beranoaguirre等。（诠释J地球科学108：2037年至2046年，2019）已经通过记录在NW-伊比利亚移置岩体的高压变质岩加热的短期脉冲加入到欧洲的石炭构造热记录一个有价值的一条信息（约350 Ma，马尔皮帕-特伊单位）。他们正确地指出，热事件的持续时间短是造山带俯冲/碰撞过程的不典型现象，但仍设想在俯冲通道内进行短时加热。本评论旨在指出类似年龄的短期热事件在欧洲很普遍，并且是受地幔（可能在羽流生成区TUZO上）的间歇加热控制的多相变质历史的一部分。
