Quality one important shortcoming , is it have various to behave , one that is such as thready pulse form " water reveals the son " , " reed catkins " of the spot of design form of the reed , " clam " of clam s light , etc . 质地不均匀是一个重要缺点，表现有各种各样，如细脉状的“水露子” ，芦花色状斑的“芦花” ，蚌?亮光的“蛤蜊性”等等。
There are typical laminated structure , soft sedimentary - slipping deformed structure , syngenetic brecciated structure in the ore which are the mirror of syngenetic sedimentation . the other type of ore has the charactristic of epigenetic mineralization , which is called as telescoped ore . the ore occurs in vein , pocket , lensoid and bedd 矿石中发育典型的纹层状构造、软沉积滑动变形构造、同生角砾构造等反映同生沉积特征的矿石构造；另一类矿石具有明显的后生成矿特点，称之为叠生改造型矿石，矿石产于脉状、囊状、透镜状及似层状矿体中，与燕山期岩浆岩及断裂裂隙构造关系密切。
Lode country assume silllike - similar silllike , and the next big anastigmatic , ground and west branch river set strench are consistent . it suffer the gravel silica rock , arena silica control . a handful of lode country or main lode country byway little orebody assume vein , or have the characteristic of balk reappear , compound of branch . these manifest the obvious characteristic of ore construct control 矿体以层?似层状产出为主，其次为大的透镜状，地表延伸与西岔河组地层一致。受砾屑硅质岩、含砾砂屑硅质岩控制。少数矿体或主矿体旁侧小矿体呈脉状、或具尖灭再现、分支复合特征。
