Hi Tomasz,

The first photo looks like a typical piece of Al-Haggounia EL3. The
veins are caused by weathering via intrusion of moisture altering the
composition of the matrix material.

The second photo is odd. I've never seen an enstatite meteorite with
a matrix like that. It could be a meteorwrong, or possibly another
type of meteorite.

The third photo also looks like Al-Haggounia.

I think these pieces are either Al-Haggounia EL3, or they are very
weathered and highly-equilibrated chondrites.

Best regards,

MikeG
