In this paper the relation between target reliability index of element in its standard service period, β, and reliability index under nuclear blast action, β_H, is discussed and derived. In addition, it is possible to use the maximum constant value of nuclear blast action and to assess its appearing probability properly. Finally, a practical design expression of load capacity is suggested.

The albite breccia belts (bodies) in the middle and upper Devonian along the Shanyang—Fengxian deep-seated fault and its both sides for about 400km were formed by tectonics,in which the Shuangwang breccia bodies have a superposition of concealed explosion. The Na-rich rocks,occurred with the albite breccia bodies or as their angular coarse fragments,are of the albite formed by hydrothermal permea- tion and metasomatism,in which the amount of hairlike ratile and its arr- angement directions clearly show the relict fabric S_0,S_1 and S_2 of protolith. According to the hydrogen,carbon and oxygen isotope compositions of ferruginous dolomite,traces of albite and quartz which are the major cem- ents,and traces of minerals and elements,the mineralized hydrothermal fluid came from the deep crustal and the fluid is probably a hydrothermal fluid of carbonatite magma. The Shuangwang gold deposit belongs to“magmatic hydrothermal one of the structural-concealed explosion albite breccia type”.It can be called the “Shuangwang-type gold deposit”for short.The genetic model of the gold deposit may be summerized as follows.firstly the south and the north palaeo- plates were joined and jammed,thus forming closely linear folds and longi- tudinal compresso-shear faults of the Hercynian and the Indo-Sinian folding belts in the region;then the direction of the compressive force changed into EW orientation because of the waves of the Cathaysian structure,thus transforming the original compresso-shear faults into tension fractures and forming metasomatic albitite-cataclastic metasomatic albitite—albite breccia; finally,the fluids containing rich Na,CO_2 and Au moved upward from the deep crustal and cemented the above breccias,thus forming the gold orebod- ies.However,the Xiba intermediate-acidity rock mass at the south of the gold deposit is not related to the gold ore formation.

沿山阳—凤县深断裂及其两侧分布的中、上泥盆统地层中的钠长角砾岩带(体),断续长达400余公里。属构造成因,其中双王角砾岩体的形成有隐爆作用叠加。与钠长角砾岩体相伴或作为其角砾的富钠岩石,系热液渗透交代成因的钠长岩,其中毛发状金红石的多寡和不同方向的排列,较清晰地显示了原岩的残留组构 S_0、S_1和 S_2。根据双王钠长角砾岩主要胶结物成分—含铁白云石及少量钠长石,石英的氢、氧、碳稳定同位素组成的测定结果以及微量矿物、元素的特征,热液来源于地壳深部,且很可能是碳酸岩岩浆热液。双王金矿属“构造—隐爆钠长角砾岩型岩浆热液金矿床”,可简称为“双王式”金矿。其成矿模式可概括为:南、北古板块的对接和挤压,形成本区的海西—印支褶皱带的紧密线状褶皱和纵向压(扭)性断裂。随后,由于华夏构造的波及,挤压变更为东西向,致使原压扭性断裂向张性转化,形成交代钠长岩—碎裂交代钠长岩—钠长角砾岩。地壳深部富钠、二氧化碳和金的气液流体上涌并胶结了上述角砾岩,形成金矿体。南侧的西坝中酸性复式岩体与金成矿作用无关。

Based on the characteristics of occurrence, form, texture and compositions of breccias in Area No. 670, this paper points out that the studied geological body was the product formed through magmatic intrusion and cryptoexplosion with the participation of volcanic residual magma and hydrothermal fluid; it also inquires into its significance in the course of uranium metallogenesis in terms of the origin of breccias discussed.

本文阐述了670地区角砾岩产状、形态、结构、组分诸方面特征,指出该地质体是在火山残浆及流体参与下,通过熔浆侵入、隐爆作用形成的产物;并在讨论该角砾岩成因的基础上,探讨了它在铀成矿作用中的意义。
