交代结构

矿石的结构以粒状结构为主、压碎结构为主，其次为交代结构。

The ore structure as granular structure , cataclastic structure , followed by metasomatic texture .

矿石金属矿物主要有黄铜矿、磁铁矿、闪锌矿、方铅矿等；脉石矿物主要有石榴石、透辉石、绿帘石、方解石等。矿石结构主要有粗晶结构、斑状结构、交代结构，次生结构。

Ore minerals have chalcopyrite , magnetite , sphalerite , galena ; Gangue minerals are garnet , diopside , epidote , calcite etc. The ore textures have coarse-grained texture , porphyritic texture , metasomatic texture , secondary textures .

变晶结构是翡翠的主体标型结构，交代结构、碎裂及变形结构对翡翠质量也有很大的影响。

The texture of jadeite jade can be classified into three types according to their geological origin : crystalloblastic texture , replacement texture , deformation texture .

具交代结构的翡翠中常因含有钠质闪石、钠长石或绿泥石，且使翡翠的粒度不均匀而使其质量变差；

The jadeite 's quality with the micro-crystalloblastic fiber texture is high , whereas that with the metasomatic texture is poor because there are sodium amphibole , albite or chlorite in it .

矿石类型以锌为主，矿物成分简单，以闪锌矿、方铅矿与石英、白云石为主，具充填、交代矿石结构、构造，矿石平均品位含Zn9.94%、Pb1.50%；

The ore is mostly composed of sphalerite , galena , quartz and dolomite and possesses filling and metasomatic texture and structure . The average ore tenor is that Zn makes up 9 . 94 % and pb 1 . 50 % .

各类矿石内部显微结构主要为不同粒级碎屑结构，其次为豆鲕粒结构，偶见凝胶结构、重结晶微细晶粒结构及交代残余结构等。

Internal microscopic structure of the various types of ore is the different size fractions debris structure , which is mainly sand debris and silt ; followed by beans oolitic ; occasionally the gel structure , crystallization superfine grain structure and metasomatic relict structure .

矿石主要结构有变余结构、粒状变晶结构、交代假象结构、环带结构、半自形-它形结构；主要构造有块状构造、浸染状构造和细脉状构造。

Ore than major structural change in the structure of granular texture 、 false account of the structure 、 ring structure 、 and a half from the shape-it is shaped structure ; the main structure with block structure 、 the infection-like structure and fine vein structure .

生物直接成矿作用的标志性结构为生物有机胶体结构，生物间接成矿作用的标志性结构为“矿交代生物”结构。

The indicatortexture of direct biomineralization is biological organic colloid texture and the indicator texture of zation is " mineralized biological " .

矿石结构有变晶结构、交代-充填结晶结构两主要类型，矿石构造以块状构造、团块状构造、细脉状构造和浸染状构造为主。

Ore textures are mainly blastic and metasomatic - infilling crystallization . Ore structures are mainly block , crumb , veinlet and disseminated .

但是自然金的粒度非常细，黄铜矿、闪锌矿、方铅矿和磁黄铁矿相互交代形成连生包裹结构，不利于铜、铅、锌、硫的分离，是该矿石浮选分离的难点。

The particle size of gold is very fine in this ore , chalcopyrite galena sphalerite pyrite and pyrrhotite are encapsulated with each other , closely coexisting with each other , which is go against the separation of copper , lead , zinc and sulfur .

喷流交代夕卡岩具交代残余结构和假角砾状构造，而喷流沉积夕卡岩具微粒状结构、雏晶结构和层纹、条纹、条带状构造，反映了二者不同的喷流成因；

Metasomatic skarn having replacement remnant texture , pseudobreccia structure , while depositional skarn , particulate crystallitic texture and ribbon , stratified structure . These reflect they are eruptive genesis ;

本文首先根据碳酸盐岩结构组分的类型、交代强度及可识别性把次生白云岩的残余结构分为交代残余结构、交代影像结构及交代晶粒结构三大类；

According to the texture components of carbonate rocks , the intension of replacement and the identifiability of the texture and the ME , the remainder textures can be classified into 3 types : replacement remainder texture , replacement image texture and replacement crystalline grain texture ;
