This refers to a mineral whose main component is tin. There are not many tin minerals, and the main ones are cassiterite (SnO 2 ) , stannite (Cu 2 FeSnS 4 ) , herzenbergite (SnS), and stannoidite (Cu 5 (FeZn) 2 SnS 8 ) . Of these, cassiterite is the most important ore mineral. Tin is concentrated with the activity of granite rich in ilmenite, and occurs in pneumatolytic-high temperature hydrothermal deposits and xenothermal deposits.

スズを主要な成分とする鉱物をいう。スズ鉱物はそれほど多くなく,そのおもなものはスズ石cassiterite SnO2,黄シャク鉱stannite Cu2FeSnS4,ヘルツェンベルク鉱herzenbergite SnS,スタノイド鉱stannoidite Cu5(FeZn)2SnS8などである。このうちスズ石が最も重要な鉱石鉱物である。チタン鉄鉱に富む花コウ岩の活動に伴ってスズは濃集し,気成‐高温熱水鉱床,ゼノサーマル鉱床などに産出する。
