多金属成矿区深地震反射剖面数据处理技术实验研究——以庐枞矿集区为例
|
摘要
针对庐枞多金属矿集区地震资料特点及浅、深多重探测目标,对深地震反射数据进行了处理技术实验研究。在区域长剖面上,为了获得矿集区地壳与上地幔结构的精细图像,解释成矿深部过程,开展了循序渐进的常规处理技术实验和精细处理技术实验。在矿区剖面,为了获得了浅层精细结构,针对变观测系统接收等特点,进一步开展了特殊处理实验。经过区域剖面与矿区剖面的多重处理实验,集成了一套矿集区深地震反射剖面数据处理方法与处理技术流程,为我国进一步的深部探测积累了技术与经验。
Aiming at the features of seismic data and detection targets of top to deep in Luzong ore concentration area,we carried out processing test on deep seismic reflection data.For regional profile,normal and fine data processing test were carried out step by step to obtain whole fine image of the crust and upper mantle and to interpret deep process of mineralization.For ore area profile,further special processing was carried out according to changeable observation system to obtain fine shallow structure.After multiple processing tests,a set of pertinent processing method and technology are integrated effectively and experience for further deep probe in ore concentrated areas was accumulated.
