In fact, what they are is spalled off chunks from the backside of the "main mass" If one saw this mass in it's entirety, what was immediately apparent was that it was oriented, a definite nosecone profile with one side missing and the back completely blasted into little rounded fingers and projections, exactly like the little blebs found. In fact it was the distribution of the little ones that I found over the years that I searched that pointed me in the right direction that led to the very fortunate result in finding the main pallasitic mass. In 1885 Dr. Kunz gave a full description of the three masses found in prior to that year, and noted that a piece approximately 40 to 50 lbs was missing. If I recall mention was made that it might be pallasitic-- exactly what I found. The sulfides that you noted certianly caused the disruption of the mass into all the smaller pieces that spalled off the backside of the larger pallasitic mass after it broke away from the larger irons. There are some small masses that have exactly the same composition as slices from the "main mass." And I recovered many of these which are now distributed in collections world wide. It is the composition of the iron component that links the irons with the pallasites. Both trace elements and the % of Ni directly link them.
