Added: 19th November 2011 Description:
I found this strangely shaped lump of metal on the beach on the North East coast of England. It is approx 35 x 25 x 25 mm. It is bronze in colour with a brown colour in the wrinkles. It weighs 65gm. It is not ferrous ( I have tested with a magnet). Could it be a meteorite?
Confidence: It might be this.
Confidence: It might be this. Notes: Slag is the non-ferrous flotsam that is scraped off the top of molten steel and used to be used as hard core. It has a high metal content but not strongly ferrous.
Confidence: It's likely to be this, but I can't be certain. Notes: A naturally occurring mineral, also called iron pyrites. I have found identical-looking specimens in Dorset at the foot of chalk cliffs.
Confidence: It's likely to be this, but I can't be certain. Notes: It won't be a meteorite, it will be pyrite or slag. Break it open. If it looks glassy inside it is slag.If it is metallic gold or silver with a very broken crystalline fracture (lots of small faces) then it is pyrite.
Confidence: It's likely to be this, but I can't be certain. Notes: This looks like haematite, which is a common iron mineral - iron (III) oxide. You could do a streak test: if you get some unglazed white porcelain (eg the back of a bathroom tile) and draw the mineral across it you should get a brownish cherry red streak. It is also possible that it is some kind of iron sulphide (like pyrite aka fools gold) that has been heavily weathered and therefore oxidized.
