摘要
岩浆混合作用对于认识岩浆演化、岩浆成岩过程和壳幔物质与能量交换等有重要意义。北京周口店地区房山复式岩体岩浆混合作用的特征十分明显和丰富,精彩地呈现了岩浆混合的方式、过程和程度,是岩浆混合作用野外地质实践教学的理想场所和天然实验室。本文总结了岩浆混合作用野外实践教学所面临的一些问题和挑战,并结合相关科学研究成果探讨了以房山岩体岩浆混合作用为例的野外地质实践教学的主要内容。
As an important geological process,magma mixing/mingling is of great significance in understanding the genesis and evolution of magma and the mass and energy interaction between the crust and the mantle.Magma mixing phenomenon is well preserved in the Fangshan pluton of Zhoukoudian,Beijing,presenting us with wonderful modes,process and degree,and making it an excellent example and natural laboratory for the field practice teaching of magma mixing.We summarized in this paper the challenges of teaching the magma mixing in the field,proposed a new route for the geological field practice teaching in the Zhoukoudian on magma mixing,and present the teaching contents.
