识别和评价浸染型金矿床的常规方法是地质方法和地球化学法。现在较少用地球物理法,主要是由于在大多数矿床中硫化物含量的百分比低。地质方法包括识别蚀变类型,特别是有利主岩中的粘土蚀变相和硅化作用。某些浸染型金矿床是产于含有杂质的薄层页岩、灰岩和白云岩中。卡林(Carlin)就是在这类岩石中发现的一例。其他如Delamer金银矿床都是在火山地区发现的。由于金的颗粒本身肉眼难于见到,通常都采用各 Conventional methods for identifying and evaluating disseminated gold deposits are geologic and geochemical. Less geophysical methods are now used, mainly because of the low percentage of sulphide content in most deposits. Geological methods include the identification of alteration types, in particular the favorable facies of clay alteration and silicification in the host rock. Some disseminated gold deposits are produced in thin layers of shale, limestone and dolomite containing impurities. Carlin is one example found in this type of rock. Other deposits such as the Delamer gold and silver deposits are found in volcanic areas. Due to the fact that the gold particles themselves are hard to see, they are usually used
