华北龙岗第四纪玄武岩:岩石成因和源区性质
Quaternary basalts from Longgang in the North China Craton: petrologenesis and characteristics of the mantle source
-
摘要: 华北克拉通东北缘龙岗第四纪玄武岩的地球化学研究为大陆碱性玄武岩的成因以及源区的性质提供了重要的依据.龙岗第四纪玄武岩为碱性玄武岩,具有类似OIB的REE和微量元素分配特征.岩石的Sr-Nd同位素轻度亏损(87Sr/86Sr =0.7044~0.7048,εNd=0.6~2.1),具有Dupal异常的高放射性成因Pb同位素组成(^206 Pb/^204 Pb=17.734~18.194,^207 Pb/^204 Pb=15.553~15.594,^208 Pb/%204 Pb=38.322~38.707).这种地球化学特征指示了原始岩浆起源于<70km深度的地幔,并经历了一定程度的橄榄岩、单斜辉石和钛.铁氧化物的结晶分异.岩浆源区中以来类似MORB软流圈物质的熔体为主,另外有少量来自EM Ⅰ性质的富集岩石圈地幔以及俯冲流体/熔体的物质贡献,显示了深部岩石圈-软流圈一定程度的相互作用以及太平洋板块俯冲的影响.岩浆源区多种端元组分的存在表明该地区岩石圈的减薄/置换受到多种因素的影响.
