摘要:

采用高镁安山岩(HMA)新的分类方法,描述了五台地区新太古代绿岩带中HMA的化学特征,并与实验的HMA以及自然界中典型的HMA(日本的Chichijima地区HMA和Setouchi地区HMA)进行了对比,显示该区HMA具有与上述HMA类似的化学特征。初步认为五台新太古代HMA产于洋俯冲带的环境,进而表明板块构造理论的适用时间范围可推演到新太古代。

Abstract:

In the light of a new classification of high magnesian andesite (HMA) this paper deals with the chemical characteristics of HMAs developed in the Neoarchean Wutai Greenstone Belt, and the HMAs have the similar chemical characteristics with the experimental HMA melts and the typical HMAs in nature: such as the HMAs from Chichijima and Setouchi areas of Japan. Recognition of the HMAs in the Neoarchean Wutai Greenstone Belt suggests the Greenstone Belt to be formed in the setting of oceanic subduction, and thus, the plate tectonic theory may also be applicable in Neoarchean.

Key words: High Magnesian Andesites(HMA), Wutai Greenstone Belt, Neoarchean, plate tectonic theory
