摘要 湖南深部构造的古老性由其在古元古代的表象所证实,而长期性则由其所分割的岩石圈块体在漫长时期内的活化改造特征所体现。本研究表明,大型的深部构造是构造、岩浆活动和矿产的集中带,沿走向的区域构造、岩浆及成矿历史是深部构造在浅部的响应。深部构造作为多次能量释放带,其交汇处有利于大型或超大型矿物资源的形成和聚集,因而对找矿预测有巨大潜力。

Abstract: The long-term activities of deep tectonics in Hunan Province were embodied by activated characters of intersected lithosphere blocks,while its antiquities were confirmed by Paleoproterozoic characters.The large scale deep tectonics might be a concentrated belt of structural deformation,magmatism and progressive ore formation during the Mesozoic.Based on geophysical and deep geological data,7 major boundary faults were proved,which separated Hunan into 4 crustal blocks:the Xuefengshan,Lianyuan-Shaoyang,Hengyang-Leiyang and Southeastern Hunan Blocks.The deep tectonics acted as the releasing zones of energy,and their crossing localities should be of great advantage to form ore deposits and accumulate mineral resources,which would have huge potentials for searching and forecasting of ore deposits.As a response of activated deep tectionics,the formational characters of Mesozoic magmatism and some related well-known ore deposits were described.
Key wordsActivated deep tectonics   Shallow response   Large-superlarge scale minerogenetic process
