Basanite and tephrite from Mt. Crater, Cape Bird and southern bank of Bonney Lake are considered as a major result of partial melting of equilibrium in the mantle, fusibility f=1. 5-7%, mantle reservior are enriched in LREE and Yb, and latite from Cape Rodeys and Cape Evens as a results of magmatic fractional crystallization, crystallinity F=58. 09-70.72%, its primary magama is almost the same as basanite in study area.
博尼湖南岸、克雷克特山和鸟角碧玄岩是地幔平衡部分熔融作用的产物,地幔部分熔融度f为1.5-7%,地幔源区为轻稀土富集型,并富集重稀土元素Yb;罗德角和伊万思角安粗岩是岩浆分离结晶作用的产物,结晶度F为58.09-70.72%,伊万思角高于罗德角,它们的母岩浆相当于本区的碧玄岩。

The mineral chemistry, trace elements and Sr-Nd isotopic geochemistry of different types of deep-seated inclusions indicate that Group Ⅰinclusions in western Shaudong could be the relicts of high degree of partial melting of the mantle-derived peridotites and then subjected to mantle metasomatism; the dunite and harzburgite in Group Ⅱ inclusions could be resulted from the metasomatism of silica-rich melts in the upper mantle; the olivine-pyroxenite and pyroxenite in Group Ⅱ and Group Ⅲ inclusions could be magmatic cumulates derived from magma underplating in the upper mantle.
不同结构类型深源岩石包体的矿物化学、元素和同位素地球化学研究表明,鲁西具有变质变形结构特征的橄榄岩类岩石包体为岩石圈地幔橄榄岩部分熔融后的残留体,其后又遭受了地幔交代作用的改造;具有变质变形结构,并叠加有矿物反应结构的纯橄岩和方辉橄榄岩类包体为古老岩石圈地幔被富硅质熔体改造的结果;具有残留岩浆结晶结构的橄榄岩、橄辉岩类岩石包体以及具有变晶结构或堆晶结构的辉石岩类包体为地幔更早期岩浆作用的在上地幔的堆积体。

The petrogenesis of intrusive rocks is discussed in this paper according to the equilibrium of minerals. It is suggests that in the Shigujian pluton, the designations of plagioclases are 15 - 25, the plagioclases are all oligoclase; the biotites are Mg-biotites, and most of the amphiboles are edenitic amphiboles or edenite; paragenetic ...
结果表明:(1)石鼓尖侵入岩中,斜长石成分较稳定,共生角门石和黑云母为岩浆平衡结晶的矿物;(2)天堂寨和九资河侵入岩中,部分斜长石和黑云母可能为熔蚀残留矿物,角闪石属于火成岩区的新生矿物,可能为斜长石和黑云母发生熔融反应所形成;(3)三个侵入体的岩石均为岩浆成因。
