rare-earth garnet

Petrologic and mineralogical data indicate its complex multi-stage metamorphic history. An earlier eclogite facies metamorphism ( p> 15 kbar) is deduced from rare omphacite inclusions within garnet.

岩石学和矿物学数据显示高压基性麻粒岩经历了多阶段变质历史，早期可能经历了榴辉岩相变质作用（p>15kbar），以石榴子石中保留的少量绿辉石为特征；

It is not known how rare this resemblance is, or whether it is most often seen in inclusions of silicates such as garnet, whose crystallography is generally somewhat similar to that of diamond;

现在尚不知这种类似稀少到何种地步，也不知道是否它最常见于象石榴石一类的硅酸盐内含物中，而这类物质的晶体结构普遍地在某种上类似于金刚石的晶体结构。
