# Is this iron ore? [closed]

Is this iron ore? I found it in the back yard in Western Australia few years back; it has a roughish surface. It was sticking out of my grass. It has sand grains stuck on it. It is reasonably hard, and a really shiny silver colour.

• Welcome to Earth Science Stack Exchange! These aren't bad photos, but it would help if you could provide a bit more information, as outlined in this guide. – kwinkunks Sep 8 '15 at 13:34
• Is it magnetic? What happens when you hold a magnet near it? Try to find a reasonable magnet, not the ones you put on your fridge – Gimelist Sep 8 '15 at 22:11
• You need to photograph these things in outside daylight as well (maybe in the shade if the sun is really bright) – Jan Doggen Sep 9 '15 at 9:20
• Find a mug or a bowl or a ceramic tile with no glaze on the bottom. If you rub the rock on the unglazed clay, what colour is the streak left behind? – haresfur Sep 9 '15 at 23:05

Hematite is iron ore - its chemical formula is $\ce{Fe2O3}$. It's a mineral that's usually red-brown, but in some cases it appears shiny with a somewhat metallic lustre - that's the "specular" bit in it. The streak of hematite is red-brown. I'm guessing that your specimen is not pure, so that's why you get a bit of grey colour in the streak.
