摘　　要：莲花塘矿田处在越北古陆与扬子古陆所夹持的裂隙槽内,成矿条件优越,目前发现了多处大型矿床,其中铅锌铜矿成矿类型有热水沉积型和“双峰式”喷流沉积型。含矿地层为中寒武系田蓬组地层,上部地层赋存铅锌铜矿、下部地层赋存铅锌锑矿,可能与同生构造关系密切。控矿条件清晰,找矿标志明显,总结出大锡板—上果、菜园子—马安山—黄家坡一带找矿前景显现。The Lianhuatang ore field is located in a fissure groove sandwiched between the ancient land of northern Vietnam and the ancient land of Yangtze,with superior ore-forming conditions.Currently,multiple large-scale deposits have been discovered,among which the lead-zinc copper deposit types include hot water sedimentary type and"bimodal"jet sedimentary type.The ore bearing strata are the Tianpeng Formation of the Middle Cambrian,with lead zinc copper deposits in the upper strata and lead zinc antimony deposits in the lower strata,which may be closely related to contemporaneous structures.The ore control conditions are clear,and the prospecting indicators are obvious.It is concluded that the prospecting prospects in the Daxiban Shangguo Caiyuanzi Ma'anshan Huangjiapo area are evident.
