Greetings list:
I recently purchased a 1502 gram beautiful half individual Suizhou and
ordered the corresponding label from Meteoritelabels.com. When the label
came in, I noticed that the TKW on the label was 260 kilos. I then
checked Meteorites A-Z, which listed a TKW of 70+ kilos. The well known
dealer that I purchased the stone from also had a TKW of 70 kilo's on his
label. I then dropped Roman a note asking him where he got his 260 kilo
TKW from. He sent the attached description from the Met Base that I have
copied below. It is confusing in that it lists both 260 kilo's, then 70
kilo's, and then 260 kilo's. I surmise that the original fall find was
70 kilo's, and that it was adjusted upward at a later time after more was
found. Does anyone on the list have an answer for this TKW
question? Any help greatly appreciated. Thanks!
