名 称：硅石矿石

主要成分：岩性为脉石英，化学成分为SiO2。

成 因：岩浆分泌的SiO2溶液沿构造裂隙充填形成，因含有钛元素而呈现粉红色（芙蓉石）。

主要用途：可用于熔剂、硅砖、硅铁、硅铝、结晶硅和一般玻璃等方面。质量好者可做玉石（芙蓉石）。

采集地点：内蒙古四子王旗乌兰哈达

Nmae：Silica Ore

Comosition：Quartz vein，consisting of SiO2.

Genesis：Magmatic fractioning created SiO2-rich solution, which infilled fractures to form the veins. Pinkish because of titanium-bearing（hibiscus rock）.

Usage：Used in making solvent, silica bricks, silica iron, silica aluminum, silicium and glass, high quality silica ore could be used as jade（hibiscus rock）.

Sample site：Wulanhada, Siziwangqi, Inner Mongolia.
