Are these METEORITES?

[Charl]

Both basalt AND meteorites can have strong magnetic properties. It may well have some hematite in it if it went through earth's pyroplastic ordeal. It could be be pyroplastic, but it's obviously not sedimentary rock. Meteorites are normally rather dense and heavy compared to metamorphic rocks. Softer than iron materials would have disintegrated upon entry and never would have gotten here in the first place. Earth's minerals melted in a volcano get nowhere near as hot as ones that blast through the atmosphere.

Try this: Scratch it against a hard surface, like hard tile or similar;

Black=(possibly) magnetite
Red=(possibly) hematite
Yellow-brown= (possibly) limonite

Or, take it to your local college and have it ID'd free.

But Stony meteorites are "softer" then iron and survive entry to fall as all the types of meteorites in that class, the chondrites, achondrites, planetary meteorites(lunar, Martian), all survive entry and land on Earth as meteorites. Iron, Stony, and Stony-Iron are the three basic types of meteorites.

Below is a complete individual stone meteorite that fell in Allende, Mexico in 1969, and a slice of a stone that fell in Pena Blanca Springs, Texas in 1946. You've got to have a good mass to begin with, because much does in fact burn up, as you pointed out. But both iron and stone will survive entry.
