目前已研制出用于在火山岩区普查冰长石-绢云母型、酸性岩-硫酸盐型和酸性岩-碱性岩型金银矿床的找矿模型.这些模型包括:(1)初步调查;(2)普查纲要,包括区域气候和地貌特征.初步调查包括:圈定中酸性火山带,用遥感方法划分构造线、交代岩田和火山中心,利用文献资料划分有找矿远景地段、矿山和Au、Sb、As和Hg存在的区段.普查纲要(要考虑本地区的覆盖程度)包括分散流地球
Up to now, some prospecting models have been developed for the general survey of the feldspar-sericite, acidic rock-sulphate and acid rock-alkaline rock type gold-silver deposits in volcanic areas.These models include: (1) preliminary investigation, (2) Census summary, including regional climatic and geomorphological features. The preliminary investigation includes: delineating medium-acidic volcanic belts, dividing the tectonic line by remote sensing, interpreting Iwata and volcanic centers, using literature data to divide prospecting prospect areas, mines and Au, Sb, As and Hg The census outline (taking into account the extent of coverage in the area) includes the dispersion of the Earth
