[QUOTE="user 4386, post: 456348, member: 4386"] Fellas, you just make it too difficult. Photos alone are rarely fully diagnostic and often of little help at all (especially when out of focus). Rocks are not minerals - to identify a rock, we first have to identify the minerals it is made of. To identify minerals we use things like hardness, streak (its powdered colour), colour, lustre, is it magnetic and whether it fizzes with acid to do this. If a rock is made of more than one mineral, we need a hand lens to be able to see the properties of each mineral separately. I have described how we do this in detail in about eight detailed accounts, each numbered. Do a search on this site of "[b]Series on identifying minerals[/b]" under my name. Tests like hardness and streak require nothing specialised to determine them, so if you could at least have a go at these before posting. [/QUOTE]
