Although tabular massive sulfide lenses are the most voluminous style of mineralization,a significant proportion of the deposit consists of semimassive sulfide.Sulfide minerals in stringer veins are volumetrically minor.Massive,banded sulfides:These tabular,lenslike bodies contain 70 to 95 vol percent fine-grained sulfide minerals.Breccia textures are uncommon and likely resulted from tectonic deformation rather than primary depositional processes.Pyrite and sphalerite are the dominant sulfide minerals,with subordinate pyrrhotite,chalcopyrite,galena,tetrahedrite,and arsenopyrite.Marcasite and native gold have also been recognized in trace amounts.Meneghinite (Pb13CuSb7S13) is the dominant lead sulfosalt mineral and it occurs in trace
amounts with lesser bournonite (PbCuSbS3),boulangerite (Pb5Sb4S11),and miargyrite (Ag2Sb2S3).Barite is not present within or above the massive sulfide lenses.Other workers recognized that massive sulfide bodies from the Wolverine deposit
contain significant amounts of selenium (up to 5.13 wt% in galena; J.Jambor,writ.commun.,1996; Layton-Matthews et al.,2008); sulfide concentrates contain an average of 0.1 wt percent Se (M.J.Beattie,writ.commun.,2000).Pyrite in massive layered sulfide lenses typically occurs as fine-grained anhedral masses and as coarse-grained porphyroblasts.It also occurs as rare,very fine grained,anhedral,colloform masses and framboids near the hanging-wall contact with graphitic argillite.Abundant,fine-grained,reddish brown sphalerite forms delicate,wispy,submillimeter- to centimeter-scale bands parallel to the S1 foliation (Fig.6B).Sphalerite compositions range from 4.1 wt percent Fe in pyrite- and sphalerite-rich massive sulfide to 10.4 wt percent Fe in chalcopyrite-rich massive sulfide.Representative sphalerite analyses (n = 13) from five samples of massive sulfide are presented in Table 1.

尽管板型块状硫化物晶体的矿化是属于大体积式,但极大部分的矿床是由半块状硫化物构成.细脉中只有少数的大体积硫化矿物.
块状联合硫化物：这些板型晶形体含有70至95 体积百分比的细颗粒硫化矿物；通常不存在角砾岩纹理,并且这是构造变形而不是原发性沉积过程所形成的结果.主要的硫化矿是硫铁矿及闪锌矿,其他从属矿物有磁黄铁矿、黄铜矿、方铅矿、黝铜矿及砷黄铁矿.同时也有微量的白铁矿和自然金；而主要的铅磺酸盐矿物是微量的辉锑铅矿(Pb13CuSb7S13),还含有更少量的车轮矿(PbCuSbS3)、硫锑铅矿(Pb5Sb4S11) 及 辉锑银矿(Ag2Sb2S3).在块状硫化物晶体中或顶部没有发现重金石.
Other workers recognized that massive sulfide bodies from the Wolverine deposit contain significant amounts of selenium (up to 5.13 wt% in galena; J. Jambor, writ. commun., 1996; Layton-Matthews et al., 2008); sulfide concentrates contain an average of 0.1 wt percent Se (M.J. Beattie, writ. commun., 2000). Pyrite in massive layered sulfide lenses typically occurs as fine-grained anhedral masses and as coarse-grained porphyroblasts. It also occurs as rare, very fine grained, anhedral, colloform masses and framboids near the hanging-wall contact with graphitic argillite. Abundant, fine-grained, reddish brown sphalerite forms delicate, wispy, submillimeter- to centimeter-scale bands parallel to the S1 foliation (Fig. 6B).
其他工人确认沃富林矿床的块状硫化物矿体有相当含量的硒（方铅矿中含量达5.13重量百分比；根据J. Jambor, writ. commun.,1996年；Layton-Matthews等人2008年文献）；硫精矿含有平均0.1重量百分比的硒（M.J. Beattie, writ. commun., 2000年文献）.在块状硫化物晶体层中的硫铁矿一般以反V形的细颗粒团以及粗颗粒变斑晶的形状体现.硫铁矿也在靠近接触石墨泥板岩的断层上盘以稀有的、非常细粒状、反V形的胶状及微球团出现.大量的细粒状、红棕色的闪锌矿形成与S1叶层平行的精细小束状、亚毫米-厘米-比例的条带（图示6B）.
Sphalerite compositions range from 4.1 wt percent Fe in pyrite- and sphalerite-rich massive sulfide to 10.4 wt percent Fe in chalcopyrite-rich massive sulfide. Representative sphalerite analyses (n = 13) from five samples of massive sulfide are presented in Table 1. Galena, tetrahedrite, and arsenopyrite all are common in the massive sulfide lenses and typically occur together as fine grained, anhedral aggregates within sphalerite-rich layers
(Table 1, Fig. 6E). Galena near the base of the Lynx sulfide lens is high in selenium (up to 4.04 wt % Se), and galena is the only mineral within the massive sulfides that contains selenium in concentrations greater than ~1 wt percent, the lower limit of detection of the energy dispersive spectrometer(EDS) microanalysis technique used.
闪锌矿成分的分布范围包括在富含硫铁与闪锌矿的块状硫化物中的4.1重量百分比的铁至富含黄铜矿的块状硫化物中的10.4重量百分比的铁.表格1显示的是对五个样本进行闪锌矿分析后的（n=13）具有代表性结果.方铅矿、黝铜矿及砷黄铁矿常见于块状硫化物晶体中,一般以细粒的反V型碎石状一起出现于富含闪锌矿的夹层之间（表格1,图示6E）.靠近林尼斯带的硫化物晶体底部的方铅矿含有很高的硒（高达4.04重量百分比）；以能量色散谱仪的检测低限,通过显微分析技术发现块状硫化物中唯一只有方铅矿的含硒量是超过1重量百分比.
