The projections of major elements of the ore-bearing wall rock which is Luoxue Formation dolomite of the Cu deposit of Dongchuan type show a series of characteristics of unusual sedimentation on Al2O3-SiO2- (CaO+MgO) , lg (SiO2/Al2O3)-lg [ (CaO+Na2O) /K2O] and (al-alk)-c diagrams . and are similar to those of the chemical sediment of present hot water of Red Sea. Co/Ni of chalcopyrite and trace elements of Luoxue Formation dolomite on the Co + Ni As-Cu + Mo +Pb + V +Zn diagram also show characteristics of hot water sedimentation. The results of REE study indicate Luoxue Formation was formed by mixture of hot water sedimentation with usual sedimentation. According to fluid inclusion research , it is believed that the metallogenic hot water belongs to Na+ (Ca2+ , Mg2+ ) HCo3-Cl-type and has vaporous components such as CO, H2O (V) , CO2 , CH4 , etc. , metallogenic T 110-214℃ and metal-logenic depth 3- 150m. Isotopes of S, C, O and H show they are mostly derived from sea water and the metallogenic hot water is mainly the sea water heated in descending convecyion cycle and a part of formation water. Combining with results of geological research, we put forward a new viewpoint of" sedimentation metallogeny of hot water by microfracture spurt". It is to say that the Cu deposit is formed by the descending sea water heated by the high heat flow, which extractes silica and mineral matters flowing through the wall rock and discontinuously spruts along the microfracture in the Luoxue period sediments solidified incompletely.

东川式铜矿赋矿围岩落雪组白云岩的常量元素投影点在Al2O3──SiO2──(CaO+MgO)图解、lg(SiO2/Al2O3)──lg[(CaO+NaO)/K2O]图解和(al─alk)──C图解上有一些非正常沉积的特点,并与红海现代热水化学沉积物有相似的特征。黄铜矿Co/Ni值及落雪组白云岩微量元素在Co+Ni─As+Cu+Mo+pb+V+Zn图解上也反映出热水沉积特征。稀土元素研究成果表明落雪组是热水沉积与正常沉积相混合的产物。包裹体研究后认为成矿热水属Na+(Ca2+、Mg2+)─HCO-3─Cl-型,并含CO、H2O(气)、CO2、CH4等气相组分,成矿温度110─214℃,成矿深度3─150m。硫、碳、氧和氢的同位素反映了这四种组分多来自海水,成矿热水主要是下渗对流循环而受加热的海水及部分建造水。结合地质研究成果,本文提出“热水微裂隙喷溢沉积成矿”的新认识,即海水下渗,受裂谷高热流加热,萃取流经围岩中的硅质及矿质在还原环境中,沿落雪期尚未彻底固结沉积物中的微裂隙间断式喷溢沉积成矿。

Based on the geological field and micrdscope observation of wallrock alteration of u- ranium deposit 622 and field and microscope geochemcal trace of major element and rare earth el-ement , two main periods of hydrothermal actions closely related to mineralization have been classi- fied here,The first is alkalic metasomatism and hematite type of uranium mineraliZation withmiddle enrichment of H R E E caused by alkalic hydrothermal action from the deeper magmatismand late mineralizatian. The second is acid hydrothermal action produced by near- surface circulat- ing underground water which was mainly from atmosphere. This process brought about furtherfractionation of LREE and HREE high HREE concentration , and superimposition of fluorite-damourite type of U ranium metallogenesis. It is suggested that hematitization , fluoritization anddamouritization phenomena which are widespread in the alterated metallogenic zone , the contentincrease of P_2O_5,MgO,TiO_2,CaO, REE and HREE,the decrease of SiO_2,Na_2Oand the ratio of LREE/HREE ,can be used as criteria for ore prospecting.
