如果你看到不止一个矿物可以称之为摇滚,但不完全。你可以有一个宝石具有硬壳的其他矿物或岩石。你需要知道每个石头都使用一个或多个矿物——定义,但有单矿物岩石为石灰岩、湿草地只能由方解石。如果你给我一个石灰岩我可以说我有一块石头,我也看到方解石,一般来说用放大镜。当我们正在寻找矿物质矿物质或思考,我们使用搜索形成良好的物种。如果你看到一个大的水晶,你可以确认它是一种矿物。有时他们是孪生。如果你看到和聚合的矿物,它是一个独立摇滚,如果有一个或多个矿物类型。如果你在一个矿石,这又不能确切。有点棘手的问题,因为你可以把矿物质的总量是一个摇滚、湿草地并非如此。 Then you have an aggregate of well formed minerals, wich is not the same as a rock. There are several definitions of rock and mineral. I took this ones: > **Rock**:"mineral matter of variable composition, consolidated or > unconsolidated, assembled in masses or considerable quantities in > nature, as by the action of heat or water." > > **Mineral**:"any of a class of substances occurring in nature, usually > comprising inorganic substances, as quartz or feldspar, of definite > chemical composition and usually of definite crystal structure, but > sometimes also including rocks formed by these substances as well as > certain natural products of organic origin, as asphalt or coal."
