A rock, by comparison, is an aggregate of minerals and/or mineraloids, and need not have a specific chemical composition. Minerals range in composition from pure elements and simple salts to very complex silicates with thousands of known forms. The study of minerals is called mineralogy.

要被归类为真正的矿物，物质必须是固体并具有晶体结构。矿物（通常）是一种无机的、天然存在的、有组织的晶体结构，由单一化合物或元素组成。矿物晶体的形成是因为它们的化学成分倾向于按照所涉及分子的形状和成分（有时随温度和压力而变化）决定的某些特定排列聚集在一起。这些排列产生了物理特性中描述的晶体形式。通常，矿物是随着溶液以某种方式发生变化而形成的，这种变化允许或迫使矿物成分凝固。这种变化可以是温度、压力、化学或浓度，并且溶液可以是水溶液或岩浆甚至气体。

PHYSICAL PROPERTIES:Classifying minerals can range from simple to very difficult. A mineral can be identified by several physical properties, some of them being sufficient for full identification without equivocation. In other cases, minerals can only be classified by more complex chemical or X-ray diffraction analysis; these methods, however, can be costly and time-consuming.
