| 摘 要： | 鲁西地区中生代有2个岩浆活动时期,中侏罗世岩浆活动规模较小,形成铜石杂岩体,锆石SHRIMP U Pb年龄167.9-183Ma,加权平均值为（175.7±3.8）Ma;早白垩世岩浆活动范围较广,生成多种岩石系列,形成济南—埠村—邹平—淄博金岭一带杂岩体和沂南县铜井、莱芜、蒙阴虎头崖、临朐铁寨等杂岩体,锆石SHRIMP和LA ICP MS U Pb测年结果为128-134Ma。

| Abstract: | There are two Mesozoic magmatic activity periods in Luxi area. Jurassic magmatic activity which formed the copper Igneous rock has a smalle scale. Its zircon age of SHRIMP U - Pb is 167.9 -183Ma, and the average weighted value is （ 175.7 ± 3.8） Ma. Magma active area in early Cretaceous is wide and formed a variety of rock series. It also formed many complex, such as complex in Jinan - BucuOn - Zouping - Jinling in Zibo area and other complex in Tongjing of Yinan county, Laiwu, Hutouya in Mengyin and Tiezhai in Liqu. Its zircon SHRIMP and LA - ICP - MS U - Pb dating results are 128 - 134Ma. |
