The presence of fragments of silicified siltstone retains their original bedding . 硅化粉的砂巖碎塊保留有原始層面。
The cardium sandstone is lithic, being composed of grains of chert, quartz, quartzite, silicified argillite, and other rock fragments . 卡迪砂巖是巖屑砂巖,由燧石,石英、石英巖、硅化泥板巖和其它巖石碎屑顆粒所組成。
Probing into silicify nickel sulfide ore flotation technology 硅酸化硫化鎳礦石浮選工藝探討
There are intensive structural and magmatic hydrothermal movement with obvious zonal surface shape alterations , which are demonstrated by silicified function , sericitization , potassium , epidotization , hornstone , etc . the ore structural fabric mainly behaves in form of filling action with minerals such as pyrite , chalcopyrite , salenite , blende and electrum , which typomorphic feature shows a hypothermal pattern of metallogeny 呈面型蝕變,分帶特征明顯。礦區(qū)內(nèi)礦體規(guī)模巨大,礦石組構(gòu)主要為以充填交代作用為主,礦石礦物主要為黃鐵礦、黃銅礦、閃鋅礦、方鉛礦和銀金礦。而且礦物的標(biāo)型特征顯示了低溫成礦的特點(diǎn)。
The gangue minerals are mostly carbonating minerals , fluorite , barite , celestite and so on ; the rock alteration is slightly silicified , carbonated , baritizated , celestited , which is low - temperature alteration . because of continual downgoing extrusion from india plate to euro - asian plate , there are some thrusting nappe structures in lanping basin related to the orogens on the two sides 礦床中礦石礦物發(fā)育典型的中低溫?zé)嵋撼梢虻牡V物組合,如黝銅礦系列、方鉛礦、黃銅礦等,脈石礦物主要為碳酸鹽類礦物、螢石、重晶石、天青石等;圍巖蝕變主要發(fā)育弱硅化、碳酸鹽化、重晶石化、天青石化等低溫蝕變組合。
