| 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. | Ore potentiality analysis of mylonite zone of hetai gold mine field 河台金矿田糜棱岩带含矿性分析 |
| 4. | The mechanical properties of mylonites and its significance to engineering geology in the southern part of tancheng - lujiang fault belt 郯庐断裂带南段糜棱岩的力学性能与工程地质意义 |
| 5. | In this time the strike - slipping mylonite , ultramylonite as well as associated igneous and magmatic intrusion and eruptive activity of volcano were formed along the fault 该时期断裂带内以走滑糜棱岩、超糜棱岩为主要形式;沿断裂出现串珠状岩浆岩体和火山喷发。 |
| 6. | It is further indicated by the fusion of various geo - factors that the major targets include gold - bearing limonitic cataclastic rock in ningwei domain , auriferous quartz in nanhua mountain and xihua mountain domain , where the 50 - 85 strike mylonite and sulfur - bearing quartz - calcite veins of cataclastic rock is the prior ore - search targets 同时,通过多源地学因素的融合还显示,宁卫地区找金的主攻对象以含金褐铁矿化碎裂岩为主,南华山、西华山地区以脉型金矿为主,且重点应在50 - 85度方向糜棱岩、碎裂岩带中寻找含硫化物的石英-方解石脉。 |
| 7. | Detail mapping shows that the yagan mcc consists of crystallized metamorphic core ( low plate ) , detachment zone and upper plate . the metamorphic core consists of can be further subdivided into two level parts low - level high metamorphic and upper - level shallow metamorphic structural slice and between them there exists a ductile shear zone . thus the whole texture of the mcc is characterized by " three layers and tow zones " this reveals a process of extensional uplift of poly - level slices by poly ductile shear zones , a characteristics of poly - level extensional structural systems . the deformational environments change vertically in a sequence of high amphibolite facies 亚干变质核杂岩由下盘结晶岩系变质核、拆离带和上盘岩系构成,其中,变质核由四个单位及许多花岗岩体(脉)组成,可进一步分为中深和中浅变质两个构造单位(岩片) ,之间发育次级韧性拆离带(花岗质糜棱岩带) ,加上上盘总体构成“三层两带”的结构特点。 |
| 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。 |
