explosive breccia meaning in Chinese
爆发角砾岩
Examples
- Based on the derivation of metallogenic matters , mineralization and wallrock conditions , the gold deposits are subdivided into three main types : volcanic thermal type , subvolcanic rock - shallow to ultra - shallow porphyry thermal type , and concealed explosive breccia type of gold deposits
根据其金矿成矿物质来源、成矿作用及产出的围岩条件可划分为火山热液型、次火山浅成斑岩热液型和隐爆角砾岩型金矿床。 - Abstract : to the principle and project that tu guangazhi proposed in 1990 , the gold ore deposits in qinling ( shaanxi ) may be classified into fouowing types : archean high - grade gneiss type , fine grained fragmental rock - carbonate rock - silicilith type , metamorphic fragmental rock type , volcanic rock type , explosive breccia type , intrusive rock exo - and endo - contact zone type . inthis paper , the geological characteristics , metallogenic geological setting , the source of ore - forming materials , digenic mechanism and metallogenetic epoch of gold ore deposits are also discussed
文摘:参照涂光炽先生( 1990 )提出的矿床类型划分原则与金矿分类方案，将陕西秦岭地区原生金矿划分为太古界绿岩建造型、细碎屑岩-碳酸盐岩-硅质岩建造型、变质碎屑岩型、火山岩建造型、隐爆角砾岩型和侵入岩内外接触型金矿，并对各类型金矿的地质特征、成矿地质背景、成矿物质来源、矿床形成机制及形成时代等问题进行了论述和讨论。 - The hydrothermal breccia and karst in the beiya area are divided into 4 types and zones , including : sedimentary tuff and breccia induced by hydrothermal explosion and sedimentation on land surface ; hydrothermal sedimentary conglomerate and gas - explosive ejecting breccia related to sedimentation in and collapsing of some shallow karst caves ; netted hydotherma1 limcstone breccia and hydrothermal explosive breccia pipe related to hydrofracturing , corrosion and explosion in the hydrothermal channels ; and yellow granular limestone formed by simmering and alteration in the deep heated water reservoir
北衙地区热水角砾岩和热水岩溶可分为4种类型和层次，即地表相爆发沉积作用形成的沉积凝灰角砾岩、热水沉积鲕状灰岩与钙华胶结角砾岩；与近地表洞穴沉积和垮塌作用有关的热水沉积砾岩和汽爆射流角砾岩；与热水通道相蚀裂和爆破角砾化作用有关的网络状灰岩角砾岩筒和热水隐爆角砾岩筒；深部相热水浸煮蚀变灰岩。
