Geotechnical engineering characteristics and key points of investigation of stratified soil 层状构造土的岩土工程特性及勘察要点
The ore mainly has cyclopean granular texture and massive and laminar structures 矿石以镶嵌粒状变晶结构,块状和纹层状构造为主。
Layered intrusions are characterized by a typical layering structure and rhythmic texture 摘要层状岩体的典型特征是其具有层状构造和韵律结构。
And distinctive layered patterns in the fossilized sediments indicated that the water that deposited them was no longer flowing north ; instead it flowed eastward 而化石沉积物中特有的层状构造,则显示沉积泥沙的水流不再往北,而改向东流。
The secondary sculpture is formed by the outgrowth of the outer tangential wall of the epidermal cell , and this kind of protuberance always occurs in the adjoining cells , which makes the laminar protuberances 这些突起是由雌性生殖单位外盖被表皮细胞的外壁向外突出形成,这种突出生长常常在相邻细胞之间同时发生,因此,出现片层状构造。
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。
