A Study on the mantle xenoliths in the Cenozoic volcanic rocks from Maguan Area, Yunnan Province

  • 自晚新生代以来,由于受印度-亚洲板块碰撞和青藏高原整体快速抬升的影响,在云南省东南的马关地区发育了大量新生代碱性火山岩.其中有的火山岩中含有丰富的地幔包体.本文提供了马关八寨碧玄岩和钾玄岩的2个全岩化学分析资料,以及石榴二辉橄榄岩、尖晶二辉橄榄岩、石榴辉石岩和石榴二辉岩包体的全岩化学和电子探针分析结果,采用矿物温压计获得各种地幔包体的平衡温压条件,建立了本区地幔地温线,并与世界典型大地构造单元的地温线进行了对比.研究表明,石榴石二辉橄榄岩的平衡温压为1209℃~1230℃和2.13~2.93CPa,石榴石二辉岩为1034℃~1095℃和1.69~2.35CPa,尖晶石二辉橄榄岩的平衡温压为944℃~1072℃和1.46~2.74GPa,其对应的深度分别为69~93km、55~75km和48~87km.因此尖晶石二辉橄榄岩与石榴二辉橄榄岩和石榴二辉岩共存,其间没有截然的界限,而是一种过渡关系.由包体平衡温压建立的上地幔地温线与华北地区地温线一样,位于澳大利亚克拉通东缘地温线与碱性玄武岩省地温线之间,但本区地温线显著高于华北地温线,与本区具有高于华北地区的大地热流值相吻合.这证明各种辉石岩和橄榄岩包体来自地幔.根据平衡压力反演的包体起源深度推测,含石榴石的二辉橄榄岩可能来源于岩石圈底部或软流圈.基于上述研究,结合高原及滇西地区新生代钾质岩浆活动时空结构的研究成果,提出马关地区新生代碱性岩浆活动和地幔包体的成因,与印度-欧亚大陆俯冲碰撞诱发的软流圈横向地幔流的活动有关.
