| 摘 要： | 通过对库鲁克塔格群常量元素、微量元素、稀土元素的分布,元素组合及元素对的研究,发现该群有3个金异常层位,并初步建立了该群的化学地层研究模式。这一模式亦适于其它时代的地层研究。

| Abstract: | This paper chooses Kuruktag Group as a stratum model in Kuruktag region,where Sinian outcrops are most complete. It is the first time to study systematically the features of distribution,association and ratio of the major elements,trace elements and rare earth elements,and the evolution. Three gold-bearing horizons were found in Kuruktag Group form. Beiyixi Formation, Altungol Formation and Yukengou Formation. The element association of drift-rocks (include turbidite)differs from normal sedimentary rocks. The chemo-strati-graphic division is in accordance with the traditional stratigraphic division. One geochemical cycle with three subcycles reflecting the climate changes, and five geochemical stages indicating the compositions were determined. This pattern may be applicable for strata of other periods. |
