Enriched mantle source for Paleoproterozoic high Mg and low Ti-P mafic dykes in central part of the North China craton: constraints from zircon Hf isotopic compositions

  • 华北克拉通中部是古元古代岩墙群最为发育的地区.以镁铁质成分为主的岩墙群可以分为变质的和不变质的两类.不变质岩墙群是在1780~1760 Ma之间大约20 Ma时间内形成的,是华北克拉通古元古代最晚期镁铁质岩浆活动的产物.不变质岩墙又可以细分成高Mg-Ti低P、低Mg高Ti-P和高Mg低Ti-P等3组.本文报道了采自丰镇附近高Mg低Ti-P岩墙样品的锆石U-Pb年龄和Hf同位素组成分析结果.新获得的SHRIMP锆石U-Pb年龄为1769±4 Ma,与其它不变质岩墙的锆石、斜锆石U-Pb年龄和^40Ar/^39Ar年龄的范围相同.高Mg低Ti-P岩墙的锆石εHf(t)值的变化范围在-6.4~+0.4之间,平均值为-2.2,略高于时代相近的花岗质岩石.由于镁铁质岩浆在上升、侵位和结晶过程中几乎没有受到地壳物质混染,因而锆石εHf(t)值可以代表镁铁质岩浆的富集的岩石圈地幔源区的特征.文献资料显示,高Mg低Ti-P岩墙的岩石圈地幔源区的87Sr/86Sr初始比值为0.7040~0.7050,平均值为0.7046,εNd(t)值为-5.6~-2.8,平均值为-4.4.
