  • A couple of deeply striated pseudomorph sections are well embedded in a couple of microcline crystal sections. A very nice synchysite pseudo after remondite at one end. Some relict aegerine in the pseudos. No brookites on this one!

  • A very nice pseudomorph consisting of a natrolite shel with a filling of very yellow interlocking crystals of calcite. The questionmark is there because there is no current mineral that forms in crystals of this shape at MSH. We're not sure what it was originally! Very good!
