Based on the geological feature of gold - bearing breccia bodies in the shuangwang gold deposit , shanxi province , author identified it to be hydrofracturing breccia bodies , are formed by hydrofracturing of the deep - seated gold - bearing and alkali - rich fluids in the devonian hydrothermal sodium - rich rock series 该水压角砾岩体是深源富碱含金流体在泥盆系一套热水沉积的富钠质岩系中发生水力压裂作用形成的。
5 ) quantitative analysis to the dayi conglomerate in the cenozoic longmenshan foreland basin has been carried out . the results indicate that the dextral strike - slip rate is 1 . 02 mm / a , the average sedimentary rate is 0 . 143 mm / a , and the average decline rate is 0 . 3mm / a 5 )对新生代前陆盆地大邑砾岩作定量分析，结果表明，大邑砾岩沉积时期，前陆盆地滑移量为1 . 02mm a ，沉积速率为0 . 143mm a ，平均沉降速率为0 . 3mm a 。
In order to analysis the paleo - current effectively on the conglomerate , i proposed a method that can be carried out by orthogonal photo in field and statistic analysis at room . it has been improved to be efficient and veracity , especially for the case that the states of gravels can not be measured directly 为了更有效的分析古流向，对砾岩发育地层，提出了野外正射投影照相?室内统计计算的方法，该方法能提高工作效率及分析准确性，尤其适用于野外不易直接测量产状的细砾岩层。
Primarily summerization on geological characteristics and new progress in scientific research of these deposits are given in this paper , the author proposes that mineralogenesis of mpcd type gold deposit is closely related to meso - neozoic volcanic - subvolcanic action ( cryptoexplosive breccia ) , tectonic movement and maturation of organic material 本人概略介绍了其矿床地质特征、研究现状及其新进展，并明确提出了该类型金矿床的成矿与中新生代火山-次火山(隐爆角砾岩)作用、构造运动及有机质的作用息息相关。
Based on the study of the 1 : 50000 geological mapping and field survey in some places , the rock groups of proterozic alashan group that was mapped by 1 ? 200000 geological survey in 1978 may be correlated the neo - archean seertengshan group in middle inner mongolia , and the third bed of zhuzhongmaodao formation is actually a series of structural conglomerate 摘要通过巴彦诺日公地区1 / 5万地质填图和重点解剖研究，认为原1 / 20万区调中所划下元古界阿拉善群大部分岩石组合可与内蒙古中部地区色尔腾山岩群进行对比，且祖宗毛道组三段实际上是一套构造砾岩。
2 ) analyses and researches systematicly the lithofacies , sedimentary facies and depositional environment of the dayi conglomerate in the cenozoic longmenshan foreland basin . this paper analyzes detailed six coarse elastics lithofacies , five mid - elastics lithofacies and three fine elastics lithofacies . establishes the association of three depositional environment types including alluvial fan and river 2 )对新生代龙门山前陆盆地大邑砾岩岩相、沉积相和沉积环境进行了系统分析和研究，划分出6种粗碎屑岩相、 5种中碎屑岩相、 3种细碎屑岩相，确定了大邑砾岩为冲积扇相、河流相沉积环境的组合。
