摘要: 根据大量资料,分析了近年来对太古宙-元古宙界线(A/P)及其附近的研究成果,并着重论述了有关构造-岩浆事件的研究及其意义,结合我国华北A/P界线的相关问题的研究概况,认为在五台山和太行山乖地的变质岩区选择典型剖面,对太古宙基底的变基性岩体进行构造背景、精确同位素年代学以及盖层的沉积特征等多科综合研究,是今后深入探讨这一领域的关键,其研究成果对明确我国A/P界线标志将提供重要依据。

Abstract: Based on a large amount of data,we analyzed the results of recent studies on the Archean-Proterozoic boundary(A/P boundary), related tectono-magmatic events and discussed the significances of these studies Considering the current situation of study related to the A/P boundary in north China,we believe it is necessary to conduct a synthetic investigation on the tectonic setting,geochronology and sedimentary features in the metamorphic regions of the Wutai Mountain and Taihang Mountain A multidisciplinary study in the future using data from typical sections in these regions will provide important constrains for defining the A/P boundary in China.
