I am currently studying limestone for GCSE and limestone is neither an element or a compound – it is in fact a ROCK and it is sedimentary A rock is defined as an aggregate of minerals – in other words it is a combination of minerals Limestone contains mainly the mineral calcium carbonate and it also contains varying amounts of silicon dioxide (SiO2), sand, silts and clays. To be classified as a true mineral, a substance must: •Be naturally occurring (i.e. formed by geological processes) •Be inorganic •Be a solid substance in which the atoms, molecules, or ions are arranged in an orderly repeating pattern extending in all three spatial dimensions •Have a specific chemical composition •Have specific physical properties Examples of minerals Quartz (SiO2) Calcite (CaCO3) Diamond (Carbon [C]) Bauxite/Aluminium Ore (Al2O3) Graphite (Carbon [C]) IN SUMMARY: limestone is a rock, which mainly consists the mineral calcium carbonate.
