通过对芦子园铅锌铁多金属矿床进行野外实地考察和典型矿石组构特征的显微鉴定,总结该矿床典型矿石组构特征.主要矿石构造包括:浸染状构造、条带状构造、脉状构造、块状构造、角砾构造等;主要矿石结构包括:结晶粒状结构、交代结构、固溶体分离结构、填隙结构、压碎角砾状结构、揉皱结构、放射状结构等.根据这些矿石组构特征及金属矿物和脉石矿物的组合、类型及自形程度和矿物在空间上的相互关系特征分析,矿区大致可划分为三期:沉积成岩期(初始矿源层形成期)、热液改造成矿期、表生期.初步认为芦子园铅锌铁多金属矿为早期沉积、后期热液改造的热液型矿床.
通過對蘆子園鉛鋅鐵多金屬礦床進行野外實地攷察和典型礦石組構特徵的顯微鑒定,總結該礦床典型礦石組構特徵.主要礦石構造包括:浸染狀構造、條帶狀構造、脈狀構造、塊狀構造、角礫構造等;主要礦石結構包括:結晶粒狀結構、交代結構、固溶體分離結構、填隙結構、壓碎角礫狀結構、揉皺結構、放射狀結構等.根據這些礦石組構特徵及金屬礦物和脈石礦物的組閤、類型及自形程度和礦物在空間上的相互關繫特徵分析,礦區大緻可劃分為三期:沉積成巖期(初始礦源層形成期)、熱液改造成礦期、錶生期.初步認為蘆子園鉛鋅鐵多金屬礦為早期沉積、後期熱液改造的熱液型礦床.

@@@@By microscopic identification of Luziyuan Pb-Zn-Fe polymetallic deposit field trips and typical ore fabric characteristics,the fabric characteristics of the deposit typical ore are summarized. The main ore structures include disseminated structure,emulsion droplet-like structure,banded structure,vein-like structure,the massive structure,brecciated structure,etc;The main ore textures include crystalline granular texture,the replacement texture,solid solution separation texture,interstitial texture,etc. According to the ore fabric characteristics and metal minerals and gangue mineral combination,type and shape since the degree and mineral in space analysis of characteristics of the relationship,the mining area can be roughly divided into three periods,which are deposit diagenetic stage(primary source bed formation),hydrothermal transformation metallogenic period,and supergene period. It was considered that Luziyuan Pb-Zn-Fe polymetallic deposit is the hydrothermal deposit for early deposition,and late hydrothermal transformation.
