I notice soulsurfer is about, so a quick question before he dissapears.
How are moldovites formed? I have one in my small collection of meteorites and am just curious.

I was not immediately familiar with moldovites
but googling that suggested moldavites and this produced a lot of references
this is one of many. They are a class of substances called Tektites (of which I am familiar) and there is a source in Moldova hence the name
When a big meteorite hits the earth it melts the rock around it and splashes are thrown out of the crater cooling very quickly and becoming like volcanic glass however the materials are usually not the sorts of stuff that come out of volcanoes and can be identified as impact originated.

many thanks, it was something i always meant to look up but one thing leads to another and.....It was the beautiful bottle green colour that attracted me, as opposed to the blackness of a tektite.
