What does it look like?
What is it?
When you think of the word ‘mineral’ and then imagine the types of colours that associate with that – you’ve probably got ‘grey’ or ‘rock-coloured’ in your head first? I hope that on this blog so far we’ve managed to show that minerals can really come in all colours – through the ‘magic’ of chemistry.
Today’s is pink! Spherocobaltite, is colbate carbonate (or CoCO3), and it’s the cobalt that gives this mineral it’s lovely pink hue. It’s a hydrothermal mineral, forming originally from a hot soup of elements. It’s usually found in veins, where the hot fluid has flowed through crack in the rock.
It you think you seen this all before, then you’ve obviously been pretty keen on our blog! The structure of spherocobaltite is the same as calcite (CaCO3), only with cobalt atoms instead of calcium ones.
Where did the structure come from?
