Re: tektites-dendrites

Hi jj,

You may have trouble finding information about the dendrites you are
looking for since the actual name of the thing you are talking about is
called a fulgurite. Fulgurites can form in a dendridic pattern which is the
branching of the arms of the structure. Dendritic minerals look quite
plant-like, and some species are often mistaken for fossils.

I have a collection of tektites, natural glasses, impactite, and fulgurite
along with a few oddities such as trinitite (melted sand from the first
atomic bomb) and molten soil and material from other atomic explosions
among other materials. I have compared tektites to fulgurite visually and
found few similarities. The most obvious is the difference in material
density between the two. Fulgurites are full of holes, while the tektites
appear solid. There are also color differences, and the fulgurites are
often covered with a sand grain coating.

Mineralogical Research has some fulgurite pictures posted various places on
their site, but here is one URL to take you directly to some pictures:

I have one picture of a rare and unfortunately developed unnatural glass
posted at the Meteorite Exchange at:

I hope this helps.

Sincerely,

Martin
