Hello All, Recently I received a thin section from Jeff Rowell of the Putorana pseudo- mesosiderite (not a meteorite). Well tonight I looked at it and my Vaca Muerta section that is silica rich for comparison...and they do not anything alike. The Putorana section I bought is also mostly from the stone phase and it looks more like a basalt (which it is) or a plagioclase feldspar rich gabbro.
The Putorana is jammed full of twinning plagioclase, similar to a eucrite like a Millbillillie. The Vaca Muerta is also known for eucrite inclusions, but it is not a plagioclase rich eucrite. Thought I'd share the results of my comparison. By the way the Putorana makes for a beautiful section if you are into terrestrials like myself.
