The same set of ductile-rheologic shear deformational augen granite samples in the Yunkai uplifted area are measured by whole-rock Sm-Nd, Rb-Sr isotopic dating system method, obtaining respectively 1414±68Ma for Sm-Nd isochron age and 490±36Ma for Rb-Sr isochron age. These ages are respectively interpreted as the time of the granitic rock formation and the time of the tectono-thermal event of ductile-rheologic shear partial melting in Caledonian, indicating that the orogeny not only took place in Caledonian, but also the more important tectono-magmatic orogeny in the late Mesoproterozic Era and can be compared with the time of global Grenville orogeny.
对云开核部韧性-流变剪切变形眼球状花岗岩石样品进行了全岩Sm-Nd、Rb-Sr同位素年龄测定,获得1414±68Ma的Sm-Nd等时线和490±36Ma的Rb-Sr等时线年龄,它们分别代表这套花岗岩的形成时代和加里东期韧性-流变剪切部分熔融构造热事件发生时间,表明云开地区不仅在加里东期发生造山运动,而且在中元古晚期发生了更为重要的构造—岩浆造山运动,其时代与全球性的格林威尔造山运动时间可以对比。

According to the research of the paper, the "migmatite" of the Sizishan Formation, Xingdong Group distributed in northern Xiao Hinggan Mountains should be a suit of gneissic quartz monzonitegranite intrusions. Their whole rockmineral Rb-Sr isochronic dating is (482±19) Ma, indicating that an Caledonian magmatic events existed in the giant granitic belt of the Xiao Hinggan Mountains.

The granitic enclaves in the central-facies porphyroblastic lava are subvolcanic rocks with forming age of 134.2±1.9Ma. There is another intrusion of subvolcanic rhyodacitic porphyry with age of 136.0±2.6Ma, in the contact zone of the two volcanic cycles in the western part of the Xiangshan complex. The U-Pb ages of the sub-quartz-monzonite porphyry and lamprophyre are 129.5±2.0Ma and 125.1±3.1Ma, respectively. This suggests that the extension in the Xiangshan region, began in K〓, was week, and earlier than that in the coastal region of Zhejiang and Fujian provinces. Extension in K〓 in Xiangshan and neighboring regions was much stronger, forming NE striking large red-downfaulted-basins.
相山中心相碎斑熔岩中的花岗质包体属次火山岩,其成岩年龄为134.2±1.9Ma,在相山西部两火山旋回的界面之间,存在另一类次火山岩的侵位,其成岩年龄为136.0±2.6Ma,岩性为次流纹英安斑岩;次石英二长斑岩及煌斑岩的成岩年龄分别为129.5±2.0Ma及125.1±3.1Ma,说明相山地区的伸展、裂解作用明显早于浙、闽沿海,在K〓就开始了,但规模并不是很大;而K〓时期的拉张作用在相山及其邻区表现的更为强烈,形成了大面积的呈北东向展布的红色断陷盆地。
