有关玄武岩地幔包体中的韭闪石,已有不少报道和研究,但地幔成因的透闪石却未见有过报道.本文将报道在新疆库地蛇绿岩套的方辉橄榄岩中,发现的4种地幔成因的含透闪石矿物组合.1 新疆库地蛇绿岩新疆库地蛇绿岩位于昆仑造山带中,其形成时代在震旦纪→早奥陶世之间.蛇绿岩中的变质橄榄岩为一推复的构造岩片,是一套亏损程度较高的方辉橄榄岩,为上地幔部分熔融残留体成因.方辉橄榄岩主要由镁橄榄石(Fo为91)、顽火辉石(En为90～95)和少量的铬尖 There have been many reports and studies on the levignite in the basalt mantle inclusions, but no reports have been made on the tremolite from the mantle.We will report in this paper that in the hibernation of the Kudi ophiolite in Xinjiang, , And four types of mantle-forming tremolite-bearing assemblages were found.1 Xinjiang Kudi ophiolite The Xinjiang Kudi ophiolite is located in the Kunlun Orogenic Belt and was formed in the Sinian → Early Ordovician period.The ophiolite The metamorphic peridotite is a thrust tectonic slide, which is a set of higher degree of karren peridotite, which is the origin of some molten residual bodies in the upper mantle.Harolite is mainly composed of forsterite (Fo 91) Stony pyroxenes (En 90 ~ 95) and a small amount of chromium tip
