Your thread title brought up the idea of meteorites.
Many terrestrial rocks will be attracted to a magnet. While it is an indicator, it is not definitive. Much of the 3/4 minus crushed basalt in my driveway is attracted to magnets.
Good guides help immensely for experienced and novices alike. I have several on meteorites and also several on identifying rock types.
Can you tell us what characteristics of these rocks lead you to believe they may be meteorites? Or any other rock type, for that matter. Perhaps describing those characteristics would be helpful in getting a more detailed opinion.
It is almost always time for more coffee.
