Hello, My question is about mesosiderites and their composition. I have just been reading the bit on mesos in Harry Mcsween's magnificent Meteorites and their Parent Planets" . He states, and I quite, on pg 210-211: " Many of the silicate fragments in these [mesosiderite]meteorites are very similar to eucrites, diogenites and howardites, basically igneous rocks from the crust of an achondrite body. What is noticeably missing from the mesosiderites is olivine..."
Well, I have a 180+ thick slice of Estherville and I can assure you that there are olivine xls present - you can shine a torch thru them! So I would like to assume that a mesosiderite is not a core-mantle sample (like a Pallasite) but the smushed up surface of a well pounded asteroid. Any thought?s sincerely!
