摘要: 冀东地区位于华北地台东部燕山台褶带的东段,是我国主要的金矿产出地之一。区内花岗岩大量分布,包括都山、蛇盘兔花岗岩基以及青山口、高家店、贾家山、峪耳崖、罗文峪等岩株。本文对高家店和蛇盘兔岩体进行LA-MC-ICP-MS锆石U-Pb定年和岩石地球化学特征研究。定年结果表明,高家店岩体的成岩时间为(198.8±0.8)Ma,蛇盘兔岩体成岩时间为(184.7±1.0)Ma,岩体形成时代都为早侏罗世。研究区内的岩石为弱过铝质I-A过渡型高钾钙碱性花岗岩类,Na2O+K2O质量分数高,富集大离子亲石元素(LILE)和轻稀土元素(LREE),亏损高场强元素(HFSE),且δEu集中于0.14~0.82,具有明显负铕异常的特性,表明成岩物质来源于壳源,形成于后碰撞环境。
