摘要
本文在前人工作的基础上,从研究东升庙矿床的地质特征入手,依据稳定同位素地球化学、微量元素地球化学、稀土元素地球化学等持征,指出东升庙矿床为与火山活动无明显联系的海底喷气沉识成因,区域变质作用仅在已成矿基础上对矿石组构和矿体形态进行了某些叠加改造。并在此基础上提出了对流循环成矿模式。
Based on the geological and geochemical data the dongshengmiao polymetallic sulfide deposits,may be considered to be of submarrine exhalative type.The ore was reformed in diagenesis and slightly metamorphosed afterwards.A hydrothermal convection model has been put forward.It may suffixiently explain the conditions and proce- sses of the formation of the deposit.This paper also shows that the gradient is indispensable.
