The yinachang fe - cu - ree deposit is one of typical deposits and mainly occurs in yinmin formation of kunyang group of middle proterozoic epoch . this paper mainly reports the results of investigation on the ree geochemistry of various rocks and minerals , the sources of ore - forming materials and the age of mineralization . the preliminary mechanism of sudden ree enrichment and mineralization in middle proterozoic has been interpreted 本论文选择迤纳厂矿床为主要研究对象，系统研究矿床不同类型岩(矿)石和矿物的稀土元素地球化学特征，探讨富稀土的成矿流体、成矿物质来源和稀土元素成矿时代，揭示昆阳裂谷初期因民组稀土元素富集的地球化学机制。
They contain rich volcanic rocks and minerals by which reliable iso - chronic data can be got , possess successive sandstone and mudstone by which accurate magneto - stratigraphic columns can be set up and distinguish geological events , and also contain a large number of wide - spread fossils which can be used to correlate strata in a large scope 与海相地层比较，陆相地层在同位素测年、磁性地层划分和事件地层学研究方面具备建立层型的优势，同样可以找到分布广泛和利于大范围地层对比的化石门类。
