Origin of Illites at Dexing Porphyry Copper Deposit,Jiangxi Province,East China：Implications for Alteration Zoning and Ore—Forming Fluid Evolution     

Zhangdong Jin  Jinchu Zhu  Junfeng Ji  Xinwei Lu  Fuchun Li 《中国地球化学学报》2001,20(2):167-176

According to differences in features of illites including spatial distribution, crystallinity index, volume of swelling layer, polytype and relationship between its index and copper grade, two typical kinds of illite can be classified within the Tongchang porphyry copper deposit, Dexing County, East China. One is a kind of hydrothermally altered minerals within the hydrothermal alteration zone, including altered granodiorite-porphyry and altered metamorphic tuffaceous phyllite near the contact zone with porphyry rockbody. The illite crystallinity and expandability are mainly affected by water/rock ratio or fluid flux, and hydrothermal illite is formed by illitization of plagioclase and/or micas during hydrothermal fluid evolution within the porphyry body and near the contact zone with wall rocks. The other is a product of low-grade metamorphism itself by illitization of smectite, whose crystallinity index is lower than the hydrothermal illite and which is of 2M₁ polytype with no swelling layer, in the altered metamorphic tuffaceous phyllite far from porphyry rockbody ( > 2 km). Moreover, the negative correlation between illite index and copper grade indicates that, within the alteration zone, the smaller the illite crystallinity, the stronger the alteration degree, and the higher the copper grade due to higher water/rock ratio. At lower levels of the porphyry body, however, the illite crystallinity (IC) values are controlled mainly by temperature and time.  相似文献

Tungsten Mineralization and Mica REE Geochemistry,Huangsha,Jiangxi     

梁书艺  夏宏远 《中国地球化学学报》1991,10(4):326-334

The Huangsha Ag-rich tungsten deposit is genetically related to a buried granite which shows apparent vertical zoning in alteration.Greisen-type W(Mo) ores coccur at the top or the intrusive and sulfide-wolframite-quartz veins developed at the major stage of mineralization are present in low-grade metamorphic rocks in the outer-contacts.The veins exhibit a reversed zonation in the vertical section with silver concentrated in the lower part in association with sulfides.Micas,characterized by high Si and low Al.are extensively developed both in the granite and in the veins.They have similar cell parameters.belonging to 2M1 type,but those in the veins are understanding of the petrogenesis, evolution and mineralization of the granite.  相似文献
