In this paper the relationship between the crystal forms and the growth mechanism of quartz and tinstone under the hydrothermal solution conditions has been studied. 本文研究了热液条件下,水晶和锡石的结晶形态和生长机制的关系,提出了水晶和锡石的生长基元为配位负离子多面体结构。
Cassiterite is a tin oxide mineral, SnO2. It is generally opaque, but it is translucent in thin crystals. Its luster and multiple crystal faces produce a desirable gem. Cassiterite has been the chief tin ore throughout ancient history and remains the most important source of tin today.
