| Ore Mineralogical Characteristics of the Luping Lead Polymetallic Deposit in Heqing of Yunnan Province and Their Geological Implications |
| The Luping lead polymetallic deposit in Heqing is a large-size concealed deposit discovered recently in Heqing, Yunnan Province. It is located on the northern side of the Beiya superlarge gold polymetallic deposit and is a component part and a new deposit type of the porphyry-hydrothermal ore-forming system of the Beiya superlarge gold polymetallic ore field. Based on a review of local geology and a comparative study of the mineralization characteristics of the Beiya deposit, the authors held that there should exist some unsubstantial structures in the axes of Beiya syncline which could provide the channel way and space for the ore-forming fluid from the Wandongshan orthophyre mineralization system. In combination with the existence of good combinatorial anomaly of Pb-Au-Ag-Zn-Cu-As-Sb in the area, the Luping lead polymetallic deposit was eventually discovered by means of drilling. The ore bodies of the deposit are hosted in the fracture zones within limestone of Middle Triassic Beiya Formation and sandstone-mudstone interlayered bedding of Qingtianpu Formation and limestone of Middle Triassic Beiya Formation. Ores of the ore deposit mainly consist of oxidized ores and mixed ores together with minor sulfide ores. The main metal component of the ores is lead along with some accessory components such as gold, silver, iron and zinc. Based on an analysis of the mineralogical characteristics as well as the distribution and modes of occurrence of useful components in the deposit, the authors put forward the suggestion that the relevant research work should be strengthened in further development and utilization of the ore deposit. |
