包裹体研究与石碌铁矿成因的探讨 总被引：1，自引：0，他引：1
Shilu iron deposit is one of the highly economically important rich iron deposits in China. Based upon the research results on its ore composition and fluid inclusions, it can be reasonably explained that the genesis of this iron deposit is such that marine voleanic sediments there suffered later regional metmnorphism and hydrothermal reformation. The temperature of regional metamorphism ranges from 465 to 536℃,while that of hydrothermal reformation from 344 to 396℃. The latter seems to be related to the migmatization of Zhan Xian stock near Shilu iron deposit, Due to the hydrothermal reformation, the ore-forming materials were mobilized and transfered from the marine sedimentary rocks, subsequently redepositing and concentrating as a rich iron deposit in the present site. 相似文献

华南某矿区成岩成矿温度的研究 总被引：5，自引：0，他引：5
华南某矿区是一个含钨石英脉矿床,同时也是一个花岗岩浸染型钨及稀有元素矿床。该矿区除有其独特的地质特征外,且与我国的同类矿床具有相似的普遍性。因此,从气液包裹体的角度来探讨其成岩成矿的物理化学条件,对该类型矿床的成因及寻找新的矿床,具有一定理论和实际意义。 相似文献

层控水晶矿床是我国目前最重要的水晶矿床的工业类型之一,分布在西南广大地区及中南、华北的某些地区,并以晶体质量高而著称。本工作以野外考察、室内测试为基础,参照人工合成试验及兄弟单位研究结果,提出了层控水晶矿床类型划分,成因特征及找矿方向。统计资料表明,我国层控水晶矿床产出的地层时代以泥盆纪占大多数,次为石炭纪,在 相似文献

某含钽铌花岗岩成岩成矿温度的研究 总被引：1，自引：0，他引：1
Formation temperatures are obtained for a tantalum-niobium-bearing granite(512-530℃）,the feldspar-quartz zone(495℃）,the quartz zone(483℃）in the pegmatoid and wolframite-quartz vein(262-273℃,no pressure corection has been made through studies of fluid inclusions in quartz,wolframite,Mn-rich columbite microlite and other minerals,The results demonstrate that petrogenesis and metallogenesis of this district are a protracted,multistage process. 相似文献
