2.This type of deposit consists of many mineralized veins of tin and tungstun which include quartz-greisen,greisen,sulfide-quartz,greisenization feldspar erc and mineralized granite of quartz-muscovite greisenization.
3.Any of several varieties of quartz or feldspar flecked with particles of mica, hematite, or other materials.
4.The fluid inclusion Rb-Sr isochron age of quartz-stibnite veins and quartz-tetrahedrite-bismuthinite-stibnite veins from the Chahansala antimony deposit is 257±23 Ma(2σ),implying that the deposit was formed during late Hercynian-early Indosinian and had connection with intracontinental deformation.
5.A mineral enclosed within another mineral, such as rutile or tourmaline in quartz.
6.In the paper,the effect of lead nitrate,sodium humate and sodium silli- cate on surface electrical properties and floatability for wolframite and main- ly associated gangues-quartz,elbaite and calcite was studied.
7.Various pieces of evidence shows that the basement rocks of the Archean Miyun group provided some ore-forming materieds and the Sanbaishan q uartz diorite intrusive and related dykes could be the source for heat and part of the ore-forming hydrothermal fluid that mixed with meteoric water during gold mineralization.

9.Abstract: The massive tripoli is a kind of soft siliceous rock which is composed of cryptocrystalline quartz.The rock could be prepared for active ultra-fine quartz by airflow pulverization and surface modification.The ultra-fine siliceous powder is a kind of high-quality filler in plastics and rubber.
