Qualitative and quantitative mineralogical and textural investigations were undertaken for the different sulfide minerals in the 1.89 Ga Lappberget deposit, with a focus on sphalerite and pyrite. Three sphalerite types were identified and associated with: (1) main massive sulfide mineralization, (2) Fe-Mn skarn ore, and (3) Ag-rich fissure veins. Sphalerite-1 contained a relatively higher amount of trace elements (Fe, Co, Ge, Cu, Sn, and Au) but is lower in Mn/Fe, Ga, and Hg compared to sphalerite-2. Evidence of tectono-metamorphic modification of sulfides is observed throughout the deposit, such as the formation of growth twins and deformation twins in sulfides, the development of high-angled triple-point junctions in recrystallized pyrite and sphalerite, and the formation of ‘ball ore’ or ‘durchbewegung’ textures within mineralized shear zones. The recrystallization of pyrite and galena may have led to the re-distribution of fluid-mobile elements (As, Cu, Zn, Pb, Ag, and Au), some of which were deposited in discordant Ag-rich fissure veins peripheral to the main massive sulfide lenses. Trace element signatures of sulfides in Lappberget are compatible with the other metamorphosed and deformed, subseafloor volcanogenic carbonate replacement (SVALS)-type deposits in the Bergslagen mining district.

对1.89 Ga Lappberget矿床中不同硫化物矿物进行了定性和定量的矿物学和组织学研究，重点是闪锌矿和黄铁矿。鉴定出三种闪锌矿类型，它们与以下物质有关：（1）主要的块状硫化物矿化；（2）Fe-Mn矽卡岩矿石；（3）富含银的裂隙脉。与闪锌矿2​​相比，闪锌矿1所含的痕量元素（Fe，Co，Ge，Cu，Sn和Au相对较高），但Mn / Fe，Ga和Hg中的微量元素含量较低。在整个矿床中都观察到硫化物的构造变质变质的证据，例如在硫化物中形成了生长孪晶和形变孪晶，在重结晶的黄铁矿和闪锌矿中形成了高角度的三点结，并形成了“球矿”。矿化剪切带中的“或” durchbewegung”纹理。黄铁矿和方铅矿的重结晶可能导致了可流动元素（As，Cu，Zn，Pb，Ag和Au）的重新分布，其中一些沉积在主周缘周围不均匀的富含Ag的裂隙脉中块状硫化物镜片。Lappberget中硫化物的痕量元素特征与Bergslagen矿区的其他变质和变形的海底火山成碳酸盐置换（SVALS）型矿床兼容。
