Isotopic age of shijuli gabbro in north qilian mountain and its geological significance 北祁連山石居里輝長(zhǎng)巖的同位素年齡及其地質(zhì)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(zhǎng)巖的巖石學(xué)特征及其構(gòu)造意義
Geochemical features and its tectonic implication of the jinningian wangjiangshan gabbros in the north margin of yangtze block 揚(yáng)子北緣晉寧期望江山基性巖體的地球化學(xué)特征及其構(gòu)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(xì)粒輝長(zhǎng)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(zhǎng)巖地球化學(xué)特征表明,它與火山巖不同源,可能是洋盆裂谷初期的產(chǎn)物。
