陆壳岩石学

陆壳岩石学是一个新的学科研究方向，它是研究陆壳，特别是其深部物质的化学、物理学与动力学的探针。８０年代初Ｆｏｕｎｔａｉｎ提出了世界上五个地区的陆壳断面，提出上、中、下地壳分别由绿片岩相、角闪岩相与麻粒岩相岩石构成。近年来笔者提出华北大陆三个地区的陆壳断面。陆壳岩石学是多次构造－岩浆事件的记录，陆壳岩石在物理与化学上的不均匀性是我们追索大陆动力学的重要科学依据。今后的发展趋势是研究陆壳细结构岩石学、陆壳类型及其动力学、陆壳岩石学与地质灾害、环境、城市地质学的关系等。

CONTINENTAL CRUST PETROLOGY

Continental crust petrology is a new direction in earth science research,and isregarded as a probe for study of the continental crust,especially the physics,chemistryand dynamics of deep materials. In the early 1980_s,Fountain proposed 5 continentalcrustal sections with the upper,middle and Iower crust are composed of rocks of thegreenschist,amphibolite and granulite facies, respectively.The author suggests 3 conti-nental crustal sections in North China. Continental crust petrology is considered a recordof muItiple tectono-magmatic events. The inhomogeneous chemistry and physics of crustalrock may provide a basis for tracing crustal dynamics. Future topics in continental crustpetrology are likely to include detailed petrological structure,types and dynamics of thecrust,and their relation to the geological hazards,the environment and urban geology.
