Isotopic age of shijuli gabbro in north qilian mountain and its geological significance 北祁連山石居里輝長巖的同位素年齡及其地質意義
Petrological characteristics and tectonic implications of the tahe gabbro in the northern part of the great xing ' an range 大興安嶺北段塔河輝長巖的巖石學特征及其構造意義
Geochemical features and its tectonic implication of the jinningian wangjiangshan gabbros in the north margin of yangtze block 揚子北緣晉寧期望江山基性巖體的地球化學特征及其構造背景
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 ) 在其曼于特蛇綠巖的層狀細粒輝長巖中獲得了鋯石u - pb年齡值為526 1ma (早寒武世) ,它被晚奧陶世花崗巖侵入。
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 東竹林蛇綠混雜巖中輝長巖地球化學特征表明,它與火山巖不同源,可能是洋盆裂谷初期的產物。
