    ISOTOPIC COMPOSITIONS AND THEIR GEOLOGICAL SIONIFICANCE OF JINGQINGDING AND DENGGEZHUANG GOLD DEPOSITS.JIAODONG

    • This paper has studied the isotopic compositions of oxygen and silica in altered system, the sulfur in sulphur minerals and the carbon,rubidium,samarium and neodymium in calaite of Jingqingding-Denggezhuang gold deposits,The results indicated that water in early mineralized hydrothermal fluid is non-meteroic mainly, meteroic water increases in late mineralization stage,mineralizing materials is derived from the crust.It's deduced that K-and Na-riched fluid by large scale and low-degree melting of the crust rework rock and leacheed mineralizing elements to form mineralized hydrothermal fluid which deposited gold with magmatic fluid at Yanshan period.
