【摘要】 本文从4个方面综述了长乐-诏安断裂带深部地质-地球物理探测研究的概况和新进展:岩浆岩活动与分布特征;地壳上地幔速度结构、Q 值结构和电性结构;地球物理场分布特征;矿产资源远景预测、开发和利用。根据在该带发现文象、晶洞花岗岩,地壳中存在低速-低 Q-高导层,低速层隆起区与莫霍面隆起区、居里面隆起区基本吻合,地球物理场显著变异,大地热流值明显偏高,存在深断裂等地壳深部构造背景等,笔者等认为地壳内可能存在着半熔融态的高温透镜体软物质,预测在长乐-诏安断裂带能够找到高温热水田。更多还原

【Abstract】 This paper briefly describes the general situation and new developments in subsurface geological and geophysical studies of the Changle-Zhaoan fracture zone from the following four aspects:magmatic rock activity and distribution features;seismic velocity,Q value and electric nature structures of the crust and upper mantle;distribution characteristics of geophysical field;and long-range forecast,development and utilization of mineral resources.Based on some deep crustal structure background discovered along this zone,such as the existence of graphic and miarolitic granites;the existence of a layer of low velocity-low Q value-high conductivity in the crust,with the upwarped district of the low velocity layer basically in agreement with the upwarped districts of the Moho discontinuity and Curie surface;salient anomalous variations in the geophysical field;notable high value of heat flow;existence of deep subsurface fractures,etc.,the author and others suggest that there might exist fritting high-temperature and lens-like soft materials in the crust,and fore- east that a high-temperature thermal field can be found along the Changle-Zhaoan fracture zone.更多还原
