mylonitic

Located on the northern margin of Qaidam massif,the Tanjianshan gold deposit occurs in the carbonaceous mylonite schist of Wandonggou Group of Mesoproterozoic Jixian System as well as in the Late Variscan intrusive rocks.

滩间山金矿床产于中元古界万洞沟群碳质糜棱片岩和华力西晚期侵入岩中。

Tanjianshan gold deposit is situated in the northern margin of Qaidam Massifand occurs in the Middle Proterozoic Wandonggou group carbonaceous mylonite schist andLate Variscan intrusive rocks.

滩间山金矿床位于柴达木地块北缘,产于中元古界万洞沟群碳质糜棱片岩和华力西晚期侵入岩中。

The granitic mylonite occurred at the left-later shear Mayinebo fault belt as veined and banded shapes, which is consistent with shear-extension direction, belonging to syn-tectonic granite.

玛因鄂博断裂带具有左型剪切活动特征,分布其中的花岗质糜棱岩呈脉状、条带状产出,展布方向与剪切拉伸方向一致,为同构造花岗岩。

This study also focused on 40Ar-39Ar dating of the biotite from granitic mylonite in the shear zone and yielded plateau ages of 347.

西秦岭北缘新阳—元龙大型韧性剪切带是分划西秦岭造山带与祁连造山带的区域主构造边界,通过对其物质组成和构造特征的研究,结合两侧不同(洋-陆)构造环境下各类地质体的研究成果,重点对剪切带内花岗质糜棱岩中黑云母单矿物进行了40Ar-39Ar定年研究。
