Finding meteorites.....

Finding meteorites.....

Finding meteorites.....

I am trying to locate a piece of a meteorite, with maybe the weight of 1 ton, that might be buried to a depth of 10 feet in a plowed field. The meteorite's structial class is finest octahedrite, consisting of mostly iron, and approximately 10 % nickel.
Would it be possible to find something of this size using a strong magnet, say suspended by a string set up to use trianglation from a distance of maybe 100 feet? Just how far would this work, if it works at all?
Thanks, Guys,
jim Peterson

RE: Finding meteorites.....

A magnet is probably not the best method, I don't believe it'll be sensitive enough.  

I recommend a gaussmeter probe, one that is sensitive enough to pick up the small, localized variations in the earth's magnetic field.  A number of gaussmeter manufacturers make what is called a gamma probe, which might work well for this.

>>  Ground penetrating radar
>>  3-axis Magnetometer should detect the mass concentration.  Airborne magnetometers are able to detect masscons.
>>  Earth resistivity measurements used for oil field exploration ought to be able to detect the anomaly as well.


RE: Finding meteorites.....

I think you are better off using a non-damped, hand-held compass.  Fluid damped ones will be less sensitive than those that aren't.

RE: Finding meteorites.....

I think that a magentometer is the ticket.  For something this size you may not need great sensitivity.  You will need to map a large area to find the patterns.  These are commonly used in archaeological work.

Another possibility is an induced seismic event, whose shock waves can be mapped with seismometers to reveal ground propagation anomalies.
