| 摘 要： | 大别造山带侵入岩出露面积占该区总面积的50％左右，不同时代的侵入岩是重塑造山带演化历史的窗口。报道了新编绘的《大别造山带及邻区侵入岩地质图（1：50万）》的编制过程及其意义。该图反映了大别造山带侵入岩的空间分布、侵位时代、岩石类型和地球化学特征。同时，为了方便查阅，对出露的侵入岩体进行了编号。研究表明．大别造山带及邻区的侵入岩侵位时代以早白垩世为主，并有少量晚侏罗世、新元古代和早古生代岩体。新元古代岩体主要呈岩株状产出于南大别和西大别红安地区，北淮阳地区亦有少量分布；早古生代侵入岩类规模较小，主要于奥陶纪一志留纪时期侵位，分别呈带状分布于造山带的南北两侧．形成双岩浆带；晚侏罗世岩体主要分布在大别山以南的长江中下游地区：早白垩世侵入岩类分布广泛，面积约占整个大别造山带的47％．认为晚中生代岩浆活动与太平洋板块同期向北西方向的俯冲和随后的伸展事件密切相关．

| Abstract: | The exposed intrusive rocks of different ages in the Dabie orogenic belt which possess about 50% of the total surface area of that belt have great significance for understanding the evolution of the Dabie orogenic belt. In order to exchange the basic information obtained from the authors recent researches funded by the National Natural Science Foundation of China with other researchers, this paper presents the first geological map of intrusive rocks in Dabie orogenic belt and its adjacent areas （1：500000）. This map is based on previous relevant maps and incorporates the latest data （including geochemical data and geochronological data） in the past two decades and the unpublished data obtained by the authors research group, It displays the spatial distribution, intrusive ages, petrologic features and geochemical features. Also, in order to improve the readability of the map, the authors give serial number to the intrusive bodies.The research shows that the Early Cretaceous intrusive bodies possess the majority of all the intrusive rocks, while Neoproterozioc and Early Paleozoic bodies are much less. Most of the Neoproterozioc intrusive bodies occur as stocks in southern Dabie, Hong＇an area in western Dabie and northern Huaiyang area. The Early Paleozoic intrusive bodies are much smaller, constituting paired magmatic belts in south and north parts of Dabie orogenic belt. The Late Jurrassic intrusive bodies are mainly distributed in the lower and middle reaches of the Yangtze River. The Early Cretaceous intrusive bodies are widely spread, covering 47% of the total area of the orogenic belt. The Late Mesozoic magma is probably associated with the northwestward subduction of Paleo-Pacific plate underneath the South China block and subsequent extensional events. |
