查询词典 crater lake

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。

All the volcanic rocks present younger K-Ar age (less than 5Ma), which can be termed as Cenozoic rocks. In general speaking, volcansim can be dividied into two eruptive stages. In the first stage, volcanic rocks for Pliocene epoch (4. 4-5Ma) consist of basanite and tephrite, which distributed on Mt. Crater, Cape Bird, and southern bank of Bonney Lake; In the second stage, volcanic rocks for Quaternary (less than 1 Ma) are mainly composed of latite, which are distributed on Cape Rodeys and Cape Evens.On the basis of geochemical data such as major elements, trace elements , rare earth elements, isotope, microprobe analysis, combined with main achievement taken by previous researcher in this area, conclusions are drawn basically as follows

所喷发的火山岩K-Ar年龄值均小于5Ma，为新生代火山岩，大体上可以分为两个喷发阶段，第一个阶段为上新世火山岩(年龄值为4.4-5.0Ma)，主要由碧玄岩和碱玄岩组成，分布于罗斯岛上的克雷克特山、鸟角和泰勒谷的博尼湖南岸；第二阶段为第四纪火山岩(年龄值均小于1Ma)，主要由安粗岩组成，分布于罗斯岛上的罗德角和伊万思角，通过主要元素、微量元素、同位素结合电子探针以及前人的研究成果，我们大体上可以得出如下认识

Basanite and tephrite from Mt. Crater, Cape Bird and Bonney Lake exhibit similar composition in major elements and trace elements, rare earth elements . They are enriched in MgO, TiO〓, transitional elements and compatible elements , and depleted in SiO〓, Al〓O〓, Na〓O, K〓O, incompatible elements and rare earth elements; Latite from Cape Rodeys and Cape Evens are different from basanite and tephrite, they are enriched in SiO〓, Al〓O〓, Na〓O, K〓O, incompatible elements and rare earth elements, and depleted in Mgo, TiO〓, transitional elements and compatible elements. Volcanic rocks in five regions have the same isotopic ratio of 〓Sr/〓Sr (0.703115-0.703334) and 〓Nd/〓 Nd (0.512892-0.513076), however,〓Pb/〓Pb ratio in volanic rocks from Mt. Crater, Cape Bird and Bonney Lake is lower than those of Cape Rodeys and Cape Evens.

在主元素氧化物和微量元素、稀土元素含量上，克雷克特山、鸟角和博尼湖南岸的碧玄岩、碱玄岩成分比较类似，均具有较高的MgO、TiO〓、过渡元素和相容元素，较低的SiO〓、Al〓O〓、K〓O、Na〓O、不相容元素和稀土元素；罗德角和伊万思角安粗岩雷同，它们具有较高的SiO〓、Al〓O〓、Na〓O、K〓O、稀土元素和不相容元素，较低的MgO、TiO〓、过渡元素和相容元素，但五地区火山岩几乎具有一致的Sr、Nd同位素比值，〓Sr/〓Sr＝0.703115-0.703344、〓Nd/〓Nd＝0.512892-0.513076，在Pb同位素比值上，五地区的〓Pb/〓Pb＝18.664-19.913，其中碧玄岩和碱玄岩比安粗岩的比值稍低。
