南极乔治王岛菲尔德斯半岛土壤矿物化学风化特征分析

本文在考察菲尔德斯半岛成土环境、土壤理化性状的基础上，分析了本区代表性土壤的粘土矿物组成，粘粒、粉粒和全土中土壤大量元素的含量。认为亚南极海洋性气候区（无冰区）土壤次生粘土矿物主要是蒙脱石、伊利石和绿泥石；土壤矿物风化过程包括脱盐基、周期性滞水氧化－还原脱铁锰和微弱的脱硅过程

ANALYSIS OF THE CHEMICAL WEATHERING CHARACTERISTICS OF SOIL MINERALS ON FILDES PENINSULA OF KING GEORGE ISLAND,ANTARCTICA

Based on surveyed results of the soil forming environment and the soil properties,this paper analyzes the clay constituent of the typical soils in the study area,the content of major elements in the clay,silt and soils.The results show:the major secondary minerals are montmorillonite ,illite and chlorite, the chemical weathering processes of the soil minerals include the desalting, stagnant oxidation reduction and very weak desilicification.
