Hello Elton,

The following excerpt is from my Tombigbee River webpage:

Most specimens in this group [tentatively IIG] have a hexahedrite-like
matrix consisting predominately of kamacite, but one mass lower in P and
higher in Ni shows a small area with a remnant coarse Widmanstätten
structure. It was proposed by Vagn F. Buchwald that these irons be
structurally classified as hexahedrite, transitional to coarsest
octahedrite (H-Ogg).

Regards,
David
