首先阐述了对早前寒武纪时期绿岩(变质火山-沉积建造)的岩石大地构造分类结合其它地质、地球物理和地球化学研究结果,通过基底动力边界各项标志的识别,新厘定了华北克拉通基底构造格架基底构造单元由大陆块壳和活动带组成大陆块壳是相对独立演化的地壳构造单元,这时的活动带是内克拉通性质的基底构造带研究表明,华北克拉通基底早前寒武纪时期不同阶段形成的大陆块壳有:阴山-冀北联合块壳、鲁冀辽联合块壳、辽东联合块壳、胶北块壳、皖北块壳、太华块壳、阜平块壳、临汾块壳和东胜-桑干联合块壳基底活动带有:大青山活动带、燕辽活动带、五台山活动带、中条山活动带、雁翎关活动带、夹皮沟活动带等认为绿岩是基底大地构造分区的重要物质标志,基底绿岩可以划分为伸展台地型绿岩和裂谷带型绿岩,后者发育于活动带前造山内克拉通裂谷盆地。
