[Rockhounds] Geology in Progress

Yes, I figured that there was a good deal of magnetite in the source rocks for those California beaches.

Nat. Rec. Area, of course, oops, sorry, I'm sure that any sand I brought back from there, must just have accidently been caught inside my shoes when I shook them out.

At various times gold has been panned from the black sands on that beach. Also diamonds have also been found there. It is now part of the Golden Gate National Recreational Area and off limits to collecting.?

Magnetite is quite common in the Coast Range. The soil from the Benitoite Gem Mine is so full of magnetite that if you drop a magnet on the ground it can be lost by being buried by dirt attracted to the magnet.?
