Feb. 9, 2002 Greetings Mr. Franco and Fellow Meteorite Enthusiasts!
Nice Picture! Nevertheless, the shiny, white clasts in your scan resemble metallic iron-nickel grains --- at least to me. If possible, you may want to try to isolate a wee piece of the clasts in question and see if it has any reaction to a drop of a dilute solution of sulfuric, hydrochloric, or acetic acid (vinegar). Examination under a microscope while conducting this test may help catch any sign of fizzling. Also, seeing whether or not the white areas are malleable will of course help draw conclusions of a metallic origin and not a product of weathering. If they are truely metal grains, there may be more than just iron-nickel and trace amounts of other elements in them. Long strewn fields!
