| 1. | Some large ore bodies in this environment at selukwe peak mine and elsewhere have been mylonitized almost completely . 在塞卢奎峰矿山等一些地方某些大的矿产在这种环境中,并几乎彻底被糜棱岩化。 |
| 2. | Incipient shearing of main crop ore shows the development of hairline mylonitized shear zones that rapidly increase up to 2mm in width . 主茬矿石的初始的错动是呈毛发状的糜棱岩化剪切带,然后很快地增大到2毫米宽。 |
| 3. | Experiment study on clay shale reinforcement at bl2 and bl3 in xin ' anjiang dam 3号坝段厚层页岩化灌加固试验研究 |
| 4. | All these rocks aforementioned are mainly parametamorphic rocks . milan , kaqiang and alamasi group underwent high - grade metamorphism of amphibolite facies , together with weak migmatism . they share the same geochemistry and total ree and many other chracters 二者主要为副变质岩石,米兰岩群和卡羌岩群、阿拉玛斯岩群变质较深为角闪岩相,普遍弱混合岩化,它们具有非常相似的地球化学特征,稀土元素总量及其它特点一致或相近。 |
| 5. | The alteration of wall rock is mainly of propylitization , silicification , carbonatization , argillization and beresitization . the characteristics of alteration show the zoning and overlapping on the space . from the inner to outside of the ore vein zoning is : silicification inner core - argillization - beresitization - propylitization 蚀变在空间上既有分带性又有相互叠加的特点,其分带从矿脉中心向外依次为硅化内核?泥化带?黄铁绢英岩化带?青盘岩化带。 |
| 6. | The research for metallogenic evolution mechanism in the region indicates that gold ore formation has undergone three stages : gold elementary source bed formation stage from the neo - archean to the paleo - proterozoic and meso - proterozoic , regional metamorphism - migmatization gold reenrichment stage at the late meso - proterozoic , structure - fluid - gold mineralization stage at the yanshan period 对矿带成矿演化机理的研究表明,金矿形成经历了3个阶段:新太古至古、中元古代金初始矿源层形成阶段;中元古代末期区域变质混合岩化金再富集阶段和燕山期构造流体金成矿作用阶段。 |
| 7. | Xiongcun copper - gold ore deposit is located in gangdese metallogenetic belt with a large scale . the ore body mainly exists in the second lithoid unit ' s tuffs and the third lithoid unit ' s dacite tufa of the cretaceous volcanic stratum , which are not only mother rock but also mineralized body 雄村铜金矿床处于冈底斯成矿带,矿床规模巨大,矿体主要赋存于白垩系火山岩地层第二岩性单元的黄铁绢英岩化硅化凝灰岩和第三岩性单元英安质疑灰岩中,上述岩石既是赋矿围岩又是矿化体。 |
| 8. | Plastic strain first starts from ambient of the porphyroblast , and then develops to rims of porphyroblast and gradually transfers to the centers of porphyroblasts . the brittle remains in the central parts of porphyroblasts come to be decreased through the plastic deformation development , which is accordance with the banding of intensity in many mylonitization zones on wild occurrences and observation in the fabrics of mylonitization rocks under microscope 长石眼球构造的形成主要是由长石与石英的韧性差决定的,塑性变形首先从斑晶的周围部分开始,逐渐向斑晶发展,脆性残斑核不断减小,这与剪切带内糜棱岩化强度分带相一致。 |
