芬兰已在三处矿化点中发现了硫锰矿:(1)在Vittinki地区强烈变质的前寒武纪沉积物中与菱锰矿、镁锰方解石(芬兰的一种新矿物)伴生;(2)在Pattijoki地区千枚状钙质片岩含闪锌矿的层位中与闪锌矿、黄铁矿、磁黄铁矿和方铅矿伴生;(3)在Sotkamo地区轻微变质的黑色片岩中与闪锌矿、黄铁矿、磁黄铁矿、黄铜矿、镍黄铁矿、方铅矿、锑硫镍矿、硫锑铁矿和黄锡矿伴生,并且在Sotkamo的黑色碳酸盐层中充填在透闪石纤维之间的空隙内.Vittinki的硫锰矿含铁量是0.7%,Pattijoki的是4.0-6.2%,Sotkamo的是4.2-7.0%.当硫锰矿中含铁量增加时,其物理性质发生变化:单位晶胞参数减小、维氏硬度值(VHN)、密度和反射率增加.含铁量在4-5%时,其内反射色(矿物内部反射半透明部分的颜色)由绿色变到红色或褐色.
Finland has identified manganese ores in three mineralization sites: (1) associated with rhodochrosite, manganese-manganese calcite (a new Finnish mineral) in pre-Cambrian sediments strongly degenerated in the Vittinki area; (2) Associated with sphalerite, pyrite, pyrrhotite and galena in the phyllosite-containing sphalerite layer in the Pattijoki region; (3) associated with the flashing of slightly altered metamorphic black schist in the Sotkamo area Zinc ore, pyrite, pyrrhotite, chalcopyrite, pentlandite, galena, stibnite, stibnite and kyanite are associated and in the black carbonate layer of Sotkamo Filling in the interstices between the tremolite fibers Vittinki has a sulfur content of 0.7% for manganese, 4.0-6.2% for Pattijoki and 4.2-7.0% for Sotkamo. When the iron content of sulfurite increases Changes in physical properties: Unit cell parameters decrease, Vickers hardness (VHN), density and reflectivity increase, and when the iron content is in the range of 4-5%, the internal reflection color (the color of the semi-transparent part of mineral reflections) Change from green to red or brown.
