摘要

千粒石是一组鲜为人知的硅酸盐矿物。在自然界中，最常见的是在火成岩中发现的形成岩石的矿物，其特征是硅含量低(欠饱和岩石)，在火成岩侵入不纯灰岩形成的接触变质岩中。它们也存在于人造炉渣和原始陨石中，是太阳系中最古老物质的重要组成部分。

Minerals explained 61: Melilites

The melilites are a group of little-known silicate minerals. In nature, the commonest are rock-forming minerals found in the igneous rocks characterized by a low silica content (undersaturated rocks), in contact metamorphic rocks formed where igneous rocks invade impure limestones. They are also found in artificial slags and primitive meteorites, where they are an important component of the oldest material in the Solar System.
