Hello from Bavaria

I would like to inform the plenum about a new website on giant
crystals and giant mineral aggregates with many rare photos and
images, to be found at

http://giantcrystals.strahlen.org/index.htm

Please have a look and enjoy the pages, which are updated often.
Please also tell us, if you have any information about giant crystals
/ mineral aggregates yourself, as we rely on your contribution to
further develop this project.

Thank you in advance and enjoy the site

Thomas

Hi, As far as I know the largest calcite monocrystal known ( as opposed
to "normal" speleothems is in Crystal Cave, Iad Valley, Carpathian
Mountains, Romania.

Not easy to access as you get to the cave by travelling along a hydro
tunnel, the cave entrance is in the roof. Totally inaccessable if the
tunnel is working.

-The Museum d'Histoire Naturelle (Minéralogie) in Paris has a huge
collection of Brazilian meter-size crystals (Deleff collection; quartz,
mica and felspars, mostly; topaz also, if my memory helps). They were
displayed some years ago, and there should be a catalogue.

-You find hundreds of links with www.google.com--->"giant crystals". You
find in particular the reference of Deleff's book

-Great museums (London, Moscow, St Petersburg, Vienna, Smithsonian) have
giant specimens, and some are displayed on the web.

-"Giant" platinum nuggets are no more than 1-2 decimeter wide. A giant
capgaronnite crystal is no more than 0.5 mm long. Size is a oecumenic
concept that Noah had already to resolve in his time of tight available
space in his arch. Obviously, he solved it with much success.

There are some links at
http://www.ScienceOxygen.com/earth73.html

The link itself does not have any photos.
It just collects some links there. But it
might be worthwhile to take a look.

What about the giant gypsum in the caves at Lechuguilla? I think some
of those are over 20' in length, and quite beautiful.

They aren't single crystals, but sheaves of blades.
