Selecting two geologic models:dome model with homogeneous overlying medium and dome and fault model with overlying fractured formation,over which a ordinary 3 D seismic data acquisition,processing and analysis have been done and following results are obtained:① seismic physical model experiment can fully model 3 D geologic structural body;② wavefield feature of eac.
本文选择了两个地质模型——上覆均匀介质的穹窿模型和上覆裂隙介质的穹窿与断层模型 ,进行常规三维地震数据的采集、处理和分析 ,得出如下结论 :地震物理模型实验完全可以模拟三维的地质构造体 ;每一个地质体的波场特征都能反映在剖面上 ;模拟的精度能满足地震勘探攻关的需要。
This paper introduces various data about Longshan dome (brachy-anticline) in Xinshaocounty, Hunan Province, China, and demonstrates that the dome (brachy-anticline) doesnot exist there on the basis of the definitions of dome and brachy-anticline, geologic sectionsand occurrence of the strata of Longshan area, as well as proposes a new viewpoint on thestructure of the district.
介绍了龙山穹窿（短轴背斜）构造的有关论述，从定义、剖面形态、岩层产状等方面论证，认为龙山穹窿（短轴背斜）构造的观点值得商榷，并对龙山地区的地质构造提出了新的看法。
According to the recent understandings of the tectonic setting of Xiao Qinling area,it is put forward that the geological model of volcanic thermal dome gold being formed in the metamorphic complex cone under A-type subduction after studying of geology and minerals in this area.
根据对小秦岭地区大地构造位置的最新认识 ,在对一系列野外地质矿产信息综合研究的基础上 ,提出“板内 A型俯冲机制下变质核杂岩内岩浆热穹窿金成矿地质模型”。
This area underwent a widespread tectonic thermal event in Haixi period resulting in dome structure,extending fault ,secondary brittle fracture belt and brittle tough fracture belt,which played very important role to contol gold mineralization in this area.
海西期本区经历了一次广泛的构造－ 热事件，并形成穹窿构造、伸展断层、次级脆性和韧脆性断裂带，它们对本区金成矿起着重要的控制作用。
The Gaolong dome is a fault block dome rather than a short axis anticline.
高龙穹窿构造是一断块穹窿，而不是“短轴背斜”；控制近ＳＮ走向金矿化硅化角砾岩带的断裂构造，是典型的调整构造。
