Isotopic age of shijuli gabbro in north qilian mountain and its geological significance 北祁连山石居里辉长岩的同位素年龄及其地质意义
Petrological characteristics and tectonic implications of the tahe gabbro in the northern part of the great xing ' an range 大兴安岭北段塔河辉长岩的岩石学特征及其构造意义
Geochemical features and its tectonic implication of the jinningian wangjiangshan gabbros in the north margin of yangtze block 扬子北缘晋宁期望江山基性岩体的地球化学特征及其构造背景
All these ductile shear zones are characterized by northward thrusting . the u - pb dating on zircons from the bedded gabbro of the qimanyuter ophiolite melange gives an age of 526 ? 1 ma ( early cambrian ) 在其曼于特蛇绿岩的层状细粒辉长岩中获得了锆石u - pb年龄值为526 1ma (早寒武世) ,它被晚奥陶世花岗岩侵入。
The geochemical characteristics of gabbros from the jinshajiang ophiolitic melange indicate that they were derived from a mantle source different from that of volcanic rocks , which may be a product in the ocean rift in the earlier stage 东竹林蛇绿混杂岩中辉长岩地球化学特征表明,它与火山岩不同源,可能是洋盆裂谷初期的产物。
