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

The basic idea is as follows: first, a kind of plane α-B-spline interpolation curve with a shape control parameter a is constructed; then, by converting the first derivatives of the curve into Bernstein polynomial, the positive conditions of Bernstein polynomial can be used to get the necessary and sufficie nt conditions for the monotonicity of α-B-spline interpolation curves, i.e., the range of the parameter a. Therefore, monotone-preserving interpolating curves can be obtained succinctly.
其基本思想是:首先构造带有形状可调参数的一类平面(-B样条插值曲线,再把其一阶导矢的两个分量分别转化为Bernstein多项式,从而利用Bernstein多项式的正性条件,得到此曲线为单调的充要条件,即形状参数的取值范围,简单、快捷地实现此参数样条曲线的保单调插值。
