auriferous
1.Gold ore main type is auriferous quartz vein type.
2.INFRARED SPECTRUM STUDY ON AURIFEROUS QUARTZ OF MAOPAI GOLD DEPOSIT IN JIANGXI
3.A particle or bit of gold found in auriferous gravel or sand.
4.THE FOUND OF AURIFEROUS MINERAL IN RED CLASTIC?STRATA OF TERTIARY PERIOD, SOMEWHERE IN QINGHAI
5.A New Model for Gold Lodes in North China Archaean Massif──Taking Zhangjiakou-Xuanhua Auriferous Metallogenic Province as an Example
6.The Archeozoic bedded formation is the potential auriferous source in this area. There is a bright future in discovery of new concentrated zones and new-type gold deposits.
7.The faults controlled the mineralization mainly and connected the deep with the surface by the upward migration of the deep-derived auriferous metallogenetic fluids via the fractured zones and by their later precipitation.
8.The authors hold that the joint actions of numerous factors such as the upper mantle uplifted zone (the mantle thinned zone of lithosphere), the upper mantle anomalous area (relatively low-velocity area), the uplifted zone of intracrustal high-conductivity layer, the deep fault (shear zone of lithosphere), the margin of the crust-upper mantle uneven masses, the basement uplifted area reflected by gravity high, the magmatic belt and tectonic intersection reflected by skipped magnetic field, control the distribution of auriferous skarn deposits and copper (associated with gold) skarn deposits.
9.Dongtian gold deposit in the middle of Yunkai uplifted area, western Guangdong Province, is chosen as an example of those deposits. Comparative studies on the chondrite-normalized RE patterns and ΣRE, LRE/HRE, δ_(Eu), δ_(Ce), N_(La/Yb), and N_(La/Sm) of auriferous quartz veins, altered gneiss-type gold ores, Caledonian gneissic biotite granite, and Late Yanshanian granite porphyry were made.
10.The Chifengshan gold-polymetallic deposit is located in the Beishan polymetallic mineralization belt. There are 114 gold-polymetallic veins in the area, among them 19 are gold veins and auriferous veins, they occurred in the marble of Jixian System Pingdingshan Group which located in the north contact zone between biotite adamellite rock body and porphyritic granodiorite stock of Later Variscan, and controlled by the contact zone skarnization belt and EW, NE, NW and NNW strike fault.
