| 摘 要： | 辽宁侵入岩石按其特征可划分为橄榄岩-蛇纹岩、辉长岩-辉绿岩、似斑状二长花岗岩-石英二长岩、钾长(环斑)花岗岩-二长花岗岩、碱性正长岩-碱性粗面岩、辉绿岩墙和岩床、安山玢岩-流纹斑岩等7个共生岩石组合。它们分别为造山前、同造山、造山后岩浆活动的产物,沿着不同地体间的断裂带分布。不同构造环境形成的不同岩石组合有不同的成矿作用。

PARAGENETIC ASSOCIATION OF THE INTRUSIVE ROCKS IN LIAONING AND THEIR DISTRIBUTIONAL FEATURES |
| |
| Abstract: | According to their characters the intrusive rocks in Liaoning can be divided in 7paragenetic associations,they are olivinite-serpentinite gabbro-diabase;porpnyroidmonzonitic granite-adamellite;potash(ring porphritic)granite-adamellite;alkalisyenite-alkali trachyte;diabsic dike-sill and andesitic porphyrite-liparophyre.Theseall resulted from magamatic activities during pre-,syn-,and post-orogenic mov-ements,usually confined to fracture zons between various terranes.These individultectonic environments let to a variety of lithologic assemblages which displayed,inturn,distingueshing mineralization. |
