一种用作宝石的绿色钙铁榴石。

A green andradite used as a gemstone .

石榴石的种类包括（铁铝榴石、镁铝榴石、镁铁榴石、锰铝榴石、钙铁榴石、钙铬榴石）。

The variety of garnet includes almandine , pyrope , magnesium-iron garnet , manganese-aluminum garnet , andradite and calcium-chromium garnet .

锡在石榴石夕卡岩矿石中主要以类质同象的方式存在于钙铁榴石中，且随Fe/Fe+Al比值的增大而增大，少数则以锡石（SnO2）包裹体的形式存在。

In garnet skarn , Sn mainly substituted Fe into andradites and its concentration always increased with the enlargement of Fe / Fe + Al ratio , minority of Sn existed in andradites as cassiterite ( SnO2 ) inclusions .

矽卡岩主要矿物为钙铁榴石，另含少量钙铁辉石、石英和方解石；矿石主要由磁铁矿、镜铁矿、方解石、石英和矽卡岩矿物组成。

The skarns consist mainly of andradite , with a little hedenbergite , quartz and calcite , while ores are mainly composed of magnetite , specularite , calcite and quartz , with some skarn minerals . 2 .
