Above are to magnetic rocks ( the silver ball is a magnet) each has different history.

 

rock one was found on the river thames foreshore, as there is so much metal and ore and rubbish etc. (contamination is a probability) i believe that it is a very long shot of being what i want it to be. On a positive side it is to heavy for its size  it is magnetic and it passes the scratch test (back of ceramics). It also tiny flecks in its surface that sparkle. there is something captivating about it, if it is not a meteorite what is it?

 

The second was found in the desert and seems to fit a meteorite description and images  i seen on the web, it is truly one of my most treasured possessions.

 

How do i go about finding out if they are meteorites?

    Dear Alex,

     

    These are very interesting objects! To comment on the first object, it is very unlikely that a meteorite would survive for long on the Thames foreshore, degredation of the specimen would happen very quickly - which is why most meteorites are found in desert environments. I would expect that, as you suggest, this is a piece of industrial waste from a metal processing process.

     

    As for the second, this is much more unusual and having been found in the desert is more likely to be a meteroite than your first object, but you don't say which desert? Location is very important in considering the identification of a specimen.

     

    All in all I think you would be best to bring these specimens in to us here at the Museum so we can get a proper look at them. The Identification Service is open Monday to Friday (10am to 5pm) in the Darwin Centre or Orange Zone.

     

    I look forward to seeing your specimens!
