| 摘 要： | 利用近红外光谱对羟基(OH-)等敏感的特性,可以区分多种蚀变矿物及其矿物的不同结晶度,如舍羟基之硅酸盐矿物(绿帘石、闪石等),碳酸盐矿物(方解石、白云石等),层状硅酸盐中单矿物(粘土矿物、绿泥石、蛇纹石等),硫酸盐矿物(明矾石、黄钾铁矾、石膏等)等；矿物的结晶度不同,其红外吸收峰形也不相同,而矿物的结晶度标志着矿化作用...

| Abstract: | The near infrared spectrum has a characteristic sensitive to hydroxyl(OH-),etc.,which can help us distinguish many kinds of altered minerals and their different crystallinity,such as hydroxyl-containing silicate minerals(epidote,amphibole,etc.),carbonate minerals(calcite,dolomite,etc.),individual minerals in phyllosilicates(clay mineral,chlorite,serpentine,etc.),sulphate minerals(alunite,jarosite,gypsum,etc.) and so on.If the crystallinity of the minerals is different,then the form of absorption peak in nea... |
