The mylonite in ductile shear zone in Wuchuan-Guyang-Dashetai area is rich in microfabrics.The mineral composition of the mylonite, as well as the test result of p-t condition of the mineral formation(t = 300-400C, p = 0.25-0.5GPa)indica-tes that the ductile shear zone was developed under the condition of defor- rmation and metamorphism of green shist facies. The value of shear strain (r) was measured as 5.77 3.4.It indicates that the deformation mechanism is simple shear and flattening.In the south of the ductile...

The mylonite in ductile shear zone in Wuchuan-Guyang-Dashetai area is rich in microfabrics.The mineral composition of the mylonite, as well as the test result of p-t condition of the mineral formation(t = 300-400C, p = 0.25-0.5GPa)indica-tes that the ductile shear zone was developed under the condition of defor- rmation and metamorphism of green shist facies. The value of shear strain (r) was measured as 5.77 3.4.It indicates that the deformation mechanism is simple shear and flattening.In the south of the ductile shear zone(Daqing Mt.and Wula Mt.), there i a strongly lineared structure of Early Froterczoic.In the north, there are oval structures and linear structures, the oval structures are dominated by Archaean metamorphic complex, the linear structures are dominated by green stones. The shear zone formed in Early Proterozoic.It shows the characteristic of ductile shear thrusting towards south.Along the shear zone gold deposits was distributed in band.The formation of the deposits is closely related to-the shear zone, especially those parts of which cut by brittle faults, as well as intruded by magmas. In those parts,gold further enriched. This suggests that the gold deposits had undergone multiple mineralization.

内蒙中部武川—固阳—大余太东西向韧性剪切带内发育明显的糜核岩显微组构。据剪切带内糜棱岩形成温压条件(t=300~400℃,P=0.25~0.5GPa),表明它是绿片岩相变质—变形环境。剪切应变值γ=5.77~3.47。变形是以简单剪切为主,兼有压扁作用。剪切带南侧是早元古宙强烈线性构造活动带,北侧是晚太古宙花岗岩—绿岩带。剪切带形成在早元古宇,早期表现为自北向南的推覆韧性剪切作用。岩金矿(化)床沿着剪切带分布。尤其在后期脆性破裂叠加及中酸性岩浆岩所在部位,金矿进一步富集,说明本区岩金矿的形成是多阶段成矿作用的结果。

Four series of precambrian metamorphic rocks have been recognized in Wutai Mt. and the adjacent Taihang Mt. Hengshan. The low metamorphosed Hutuo Gr. with its thick bottom conglomerate overlies unconformably on wutai Gr. Hengshan complexes belong to deeply metamorphosed part of Wutai Gr. Low-middle metamorphosed Wutai Gr. which drived from volcanic rocks is thrown up on Fuping Gr. toward east. The Fuping Gr. undergo metamorphism of high amphibolite facies is formed by Carbonate formation. Both the Wutai Gr....

Four series of precambrian metamorphic rocks have been recognized in Wutai Mt. and the adjacent Taihang Mt. Hengshan. The low metamorphosed Hutuo Gr. with its thick bottom conglomerate overlies unconformably on wutai Gr. Hengshan complexes belong to deeply metamorphosed part of Wutai Gr. Low-middle metamorphosed Wutai Gr. which drived from volcanic rocks is thrown up on Fuping Gr. toward east. The Fuping Gr. undergo metamorphism of high amphibolite facies is formed by Carbonate formation. Both the Wutai Gr. and the Fuping Gr. are synchronous out-of-phase deposits. In the past, the nappe ductile shear zone between them was regarded clastic rock of the bottom of Wutai Gr..Largely distributed gray gneiss in Hengshan complex and Fuping Gr. intruded during Wutai period. The Wutai Gr. Fuping Gr. and Hengshan Complex construct the crystalltine basement at 2800Ma. They were folded. metamorphosed and finally intruded by the gray gneiss at 2500Ma.

五台山及与之毗连的太行山、恒山,发育着四套早前寒武纪变质岩系.浅变质的滹沱群以巨厚的底砾岩不整合在五台群之上.高角闪岩相的恒山杂岩是五台群深变质及部分熔融的产物,以火山岩为主体的中浅变质的五台群向东推覆在浅海碳酸盐建造的经受高角闪岩相变质的阜平群之上,两者属同时异相的沉积.它们之间的推覆韧性剪切带被过去认为是五台群底部碎屑岩(实系滹沱群下部地层)所沉积不整合。 恒山杂岩和阜平群中大面积分布着五台期侵入的灰色片麻岩.有证据表明五台群、阜平群及恒山杂岩都是在2800Ma结晶基底上发育起来,同时在2500Ma遭受褶皱,变质并被灰色片麻岩所侵入。

Through investigation and studies on the structural rocks in Faku area,North Liaoning,it was determined that there is a large scale nappe ductile shear zone.Based on the isotopic age of syntectonic intrusive rocks,the ductile shear zone was considered to be forming during Hercynian Indosinian epoch,which is identical with the final forming time of Tianshan Xing′an fold system.

通过对辽北法库地区构造岩的观察和研究,确定了本区存在一大型推覆韧性剪切带。根据同构造侵入岩的同位素年龄,确定该韧性剪切带形成时期为海西-印支期,这与天山-兴安褶皱系最终形成时间相一致
