Is lime stone a mineral

Answer 1

Usually mixtures, although some are compounds. If you want to consider things like gold, platinum, and copper nuggets and/or diamonds as "stones" they can also be elements (ignoring inclusions and impurities, which would make these too mixtures).

Some examples:

1. mixtures - granite, basalt, sandstone, meteorite
2. compounds - galena, fools gold, quartz, rock salt
3. elements - gold nugget, platinum nugget, copper nugget, diamond

Answer 2

The answer was a challenge to figure out, but I found it. Yes a birthstone IS a mineral.

Answer 3

Yes, minerals aren't rocks, as rock are composed of one or more MINERALS, like Galena. A plain mineral is composed of one substance, like copper

Answer 4

It depends on what 'stone' you're talking about. Most rocks are made from minerals. So, stones might not really be 100% minerals, but minerals might have a percentage of the stone/rock.

Answer 5

Yes and no. Stone typically refers to larger pieces than rock does (e.g. building stone, grave stone, stone slab). Gravel is even smaller pieces. The materials are often the same.

Answer 6

Limestone is a sedimentary rock.
