滇西芦子园铅锌矿床蚀变矿化特征分析

摘要

Luziyuan Pb-Zn polymetallic deposit is located at Zhenkang anticlinorium which is on the south sec-tion of Baoshan block in the southwest Sanjiang metallogenic belt.Four main mineralized zones are included in this area,namely I,II,III and V.Among them,II-V1 ,II-V3 and III-V5 in No.II mineralized zone con-tain the main orebodies.Through research the author believes that the deposit shows obvious mineralization-alteration zonality from deep to superficial part.It appears that the orebodies are controlled by faulted struc-ture and occur as banded,stratified,stratoid and veined in form along fault fractured zone in the trend of northeast.The analysis and summary of characteristics of mineralization and associated elements in this area in this paper provided basis for future prospecting works.%芦子园铅锌铁多金属矿床位于西南三江成矿带保山地块南段之镇康复背斜内。矿区主要包括Ⅰ、Ⅱ、Ⅲ、V 共四条主矿化带,其中,Ⅱ号矿化带中Ⅱ-V1、Ⅱ-V3和Ⅱ-V5为主矿体。研究认为由深部至浅部该矿床表现出明显的矿化-蚀变分带性；矿体受断裂构造控制明显,为条带状、层状-似层状和脉状,沿断裂破碎带呈 NE 向产出。通过对矿区矿化及伴生元素特征的分析总结,为下一步找矿工作提供依据。
