摘要: 马顶山新类型含稀土钨锰矿是河南省地质科学研究所在开展1∶5万舞阳—鲁山地区区域地质矿产调查时发现。矿体主要产于中元古界汝阳群(Pt2Ry)云梦山组(Pt2y)下部石英砂岩、泥岩节理带中。矿石中的稀土矿物Eu和W均以离子状态分布于硬锰矿的晶格中。矿床成因与区域断裂构造、中元古界熊耳群(Pt2Xn)马家河组(Pt2m)基性-偏中性火山熔岩建造与中元古界汝阳群(Pt2Ry)云梦山组(Pt2y)之间不整合面以及隐伏花岗岩体有关。这种成因类型的钨锰矿在该地区是首次发现。

Abstract: The new type of rare earth bearing tungsten manganese deposit in Madingshan is discovered by the Institute of Geosciences of Henan Province during the investigation of 1∶50 000 regional geology and mineral resources in Wuyang-Lushan area. The ore bodies mainly occur in the joint zone in quartz sandstone and mudstone in the lower part of Yunmengshan Formation (Pt2y) of Mesoproterozoic Ruyang Group(Pt2Ry). The rare earth minerals Eu and W in the ore are both distributed in the lattice of the pyrolusite as ions. The genesis of the deposit is related to the regional fault structure, the unconformity between the basic to intermediate volcanic lava formation in the Majiahe Formation (Pt2m) of Middle Proterozoic Xionger Group (Pt2Xn) and the Yunmengshan Formation (Pt2y) of Middle Proterozoic Ruyang Group (Pt2Ry), and the concealed granites. This type of tungsten-manganese deposit is discovered for the first time in this area.
