霍邱岩群
时代属新太古代。分布于安徽省霍邱和吴集一带，为深变质岩系，据钻孔资料命名。分为上下两岩组：下岩组为一套混合岩系，条痕、条带和眼球状混 合岩夹斜长角闪片麻岩、黑云斜长片麻岩、斜长角闪岩和黑云片岩残留体；上岩组为含铁岩系，主要有石榴黑云斜长片麻岩、矽线黑云斜长片麻岩、云母石英片岩、十字石榴子石英片岩、变粒岩、大理岩、斜长角闪岩夹数层铁矿。上岩组原岩为泥砂质碎屑粘土质碳酸盐岩、夹铁质碎屑岩和基性凝灰岩，属滨海沉积。变质程度为角闪岩相。黑云斜长片麻岩和黑云变粒岩全岩RbSr等时线年龄(27.4±0.8)亿年，上岩组8个样品全岩RbSr等时线年龄(27.4±0.6)亿年等。与泰山群相当，其上被第四系覆盖。
