查询词典 pyritization

Rare elements and REE are mainly enriched in gray-black trachyte and less in other rocks. In addition, schistosity, pyritization, silicification and carbonation in gray-black trachyte are contributed to enrich rare element and REE. It is suggested that alkaline rocks in Hongyang area have the characteristics of subvocanics, and alkaline rocks in Hongyang and Miaoya areas all came from upper mantle and mixed with some substances of crust. Intrusion of alkaline rocks is related to the occurrence, development and evolvement of the deep rupture zone in the areas.

The relationship of ore-forming fluid salinity-aqueous cation lg demonstrated that water-rock reaction was also one of the potential gold deposition mechanisms besides mixing with meteoric water. All of these were consistent with that sericitization and pyritization hydrothermal alteration were extensively/intensively distributed (as high as 33%), gold grade linearly correlated with degree of alteration,∑REE depletion and δ〓O enrichment

成矿流体盐度-液相主要阳离子组分1g演化规律研究表明，除与大气降水的混合-稀释外，水-岩相互作用也可能是造成金沉淀的重要因素，这与本文所研究金矿床中绢云母化、黄铁矿化等热液蚀变广泛发育(可高达33％)，Au品位与热液蚀变程度、REE亏损量及δ〓O富集规模表现出较为明显的线性关系等一系列地质事实相吻合

The main types of the wall-rock alteration are silicification,potash-alteration,pyritization,sericitization,chloritization and carbonatization,of which the strong silicification,potash-alteration and pyritization are closely related to gold mineralization.

流体—岩石反应引发的围岩蚀变是造成萑香洼金矿床金沉淀成矿的主要原因。

It occurs in granodioritic porphyre and granitic porphyre and the spatial distribution of the jade veins are controlled by lithology. The raw jade is in multi-colors with scaly blastic and massive textures under microscope. Wallrock alteration is developed and characterized by zoning as sericitization, kaolinization and pyritization.

玉石矿脉的空间分布受岩性控制，赋存于花岗闪长斑岩或花岗斑岩中；玉石原石色彩多样，岩石以显微鳞片变晶结构和块状构造为主；矿区围岩蚀变发育，具有绢云母化、高岭土化和黄铁矿化的蚀变分带现象。

The main alterations related to gold mineralization are pyritization、silicification and carbonatization.

与金矿化有关的蚀变类型主要有黄铁矿、毒砂化、硅化、碳酸岩化和粘土岩化等。

Besides silicification and pyritization, argillation is an important type of wall rock alteration distributed extensively in the gold ore field.

矿体分缓倾顺层矿体和陡倾穿层矿体，分别受NS向缓倾断裂和陡倾断裂构造控制。

Calculations based on Grosens'component-volume equation show that,wit the intensification of mylonitization,increasing amounts of SiO_2 and FeO are brought in,which is geologically expressed as intensified silicification and pyritization.

根据Gresens的成分－体积关系式所获得的计算结果表明：SiO＿2、FeO随着糜棱岩化程度加强而带入量增加，在地质上表现为硅化、黄铁矿化加强

Interval 4 has an increasing down-core enhancement of authigenic greigite, which is interpreted to have formed due to arrested pyritization resulting from consumption of pore water sulfate with depth.

第4段，自生胶黄铁矿随深度增多，它是沉积物孔隙水中的硫酸盐随深度增加消耗增多、黄铁矿化作用受到抑制的结果。

Ore deposit, have been studied detailly; the orebody pattern (sedimental bedded ores combined with stringer ores of hydrothermal origin) is also outlined; four metallogenic epoches are devided; the zoning of mineralization (including zones of ores, elements, mineral assemblages and temperature of mineralization) have been depicted; the main types of wall-rock alteration are characterized as propylitization of basic rocks and pyritization-sericitization-silicification of acidic pyroclastic rocks; the origin of ores and seven kinds of main minerals have been studied; and the metamorphism and deformation of orebodies is thought mainly due to the shearing and the intrusion of subvolcanic rocks

研究了七个矿化带特别是I号矿床的矿床地质特征，描绘了矿体的双层结构(沉积矿石与热液充填交代的细网脉状矿石)，划分了四个成矿期次，区分了矿化分带(包括矿石组构的成因分带、元素分带、矿物组合分带、温度分带)，指出了围岩蚀变的主要特征是细碧岩青盘岩化而石英角斑质凝灰岩黄铁绢英岩化；对矿石及七种主要矿石矿物的成因作了研究；探讨了矿体的变质、变形，指出韧性剪切及次火山岩侵入的热力作用和应力作用是导致矿体变质变形的主要原因
