Characterization of minerals containning manganese and othertransition elements

1)晶体化学对锰四榴石、含Rb或Ba的二氧化锰矿物、含Fe或Ni的橄榄石、pumpellyite、vesuvianite、锰氧化物矿物和钙锰矿进行了晶体化学讨论。2）描述矿物学描述了Sonolite、Alleganyite、蔷薇辉石、锰针铁矿、Johannsenite、Nambulite、Ardennite、苏铁辉石、铁辉石、贝芒石、白榴石和各种二氧化锰矿物。4）层状锰矿床的产出方式探讨了层状锰矿床的地质时代、原生锰矿石的形成过程、浅成低温热液锰矿脉中的矿物共生、大洋沉积物中的锰微结核和铁锰矿。

1)Crystal chemistryManganese tetragonal garnet, Rb or Ba bearing manganese dioxide minerals,Fe or Ni bearing olivines, pumpellyite, vesuvianite, manganese oxide minerals and todorokite were crystallochemically discussed.2)Descriptive mineralogySonolite, alleghanyite, rhodonite, Mn-hedenbergite, Johannsenite, nambulite, ardennite,sursassite,tirodite, bementite, alabandite, and various manganese dioxide minerals were described.3)Synthetic mineralogyTephroite,rhodonite, pyrochlor, bementite, braunite, ferrian braunite,dannemorite, grandite, hydrograndite and rhodochrosite were synthesized and their synthsized conditions were described.4)Mode of occurrencesGeological age of bedded manganese ore deposits, the process of formation of primary manganese ores, mineral paragenesis in epithermal manganese ore veins and manganese micro nodules and iron-manganese ore in oceanic sediments were discussed.
