main group pallasite | | 1 % or less by volume | mixture of iron-nickel alloy and non-metallic minerals | from angular fragments to rounded | 35 to 85 % by volume | strewn fields, elongated footprints which depends on impact angle, airbursts, and impact velocity | recorded by eyewitness or inferred from dating methods | higher than that of average solar system material | 2.5 to 4 degrees C per million years | based on the locale, region, or nearby town in which the fall occurred | from homogeneous to heterogeneous | 78 to 97 kilometers | Fo 88+-1 | | | PAL | 1.5 % of meteorite falls | | 7207 kg | 1 % or less by volume | in degrees, minutes and seconds of lattitude and longitude | heterogeneous elements are zoned between grain rim and core | metallic iron plus olivine; core/mantle boundary samples | 0.1 to 7.3 % by volume | 0.3 to 2.8 % by volume | pallasite | typically one centimeter | always greater than 4 % | | | 33 | planet or asteroid much larger than 100 km in diameter | schreibersite | |
