中文摘要:
      龙湾铅锌矿床赋存于早白垩世正长花岗岩与中奥陶统马家沟组碳酸盐岩接触带附近,围岩蚀变强烈.铅锌矿石微量元素特征与正长花岗岩较为相似,矿石Co/Ni值为2.93~4.32,具有岩浆热液成因矿床的特征.矿石稀土元素配分模式为右傾的轻稀土富集型,自矿石到花岗岩体,其稀土总量73.92×10-6到277.42×10-6逐渐升高.碳氧同位素特征显示成矿热液主要为岩浆水.矿床成矿物质主要来源于花岗岩体,矿床为典型的矽卡岩型矿床.
英文摘要:
      Longwan Pb-Zn deposit is located in the outer contact zone of the Early Cretaceous syenite with the Middle Ordovician Majiagou Formation,where the wall rock strongly alterated.The characteristics of trace elements of lead-zinc ore and syenogranite granite are very similar.The Co/Ni value of ore is 2.93 to 4.32,which is characterized by magmatic hydrothermal origin.The REE distribution pattern of ore is the right-handed light rare earth enrichment type.From ore to granite,the total amount of rare earth increases from 73.92×10-6 to 277.42×10-6.The characteristics of carbon and oxygen isotope indicate that the hydrothermal solution is mainly composed of magmatic water.The ore-forming material is mainly derived from granite body,and the deposit is a typical skarn type deposit.
