How are these formations being made????

Postby Chads93GT » Oct 8, 2008 6:33 pm

What is causing the GLITTERY white formations? im stumped.

Calcite. different minerals or impurities can create different colors. Most "pure" calcite is white. Crystal size can affect the glittery factor. The odd thing is that generally areas with a sandstone cap don't get much formation action since the water has a tough time getting down. Of course it might be highly fractured....

Sounds like Breezeway. Over a mile of crazy white formations on top of dark red mud and limestone. Sandstone is close by too. Check out the pictures in this link. http://www.socomogro.org/gallery/breezeway

Chad

The ladder and bridge were built to cross through a flowstone area and over a lake. in order to see the rest of the cave. The cave is very humid and the trail gets muddier the deeper you go into the cave. Over the years we have tried various methods to keep the area clean, but few have worked. Lots of mud has been transfered and cleaned back up. With the new ladder and bridge in place, you now take off your outer layer of clothes while passing through. We've started to do some major cleaning on the area using battery powered shop vacs and back pack sprayers. I call it a conservation masterpiece in progress. I'm guessing it will be one of the cave trips offered during the Spring BOG meeting.

How about you show me yours and I'll show you mine? :shhh:

Surely you wouldn't leave behind a photographer :big grin: Of course I'd have to get to CO first.....

After we prep the moulds, but before we spray in the fiberglass, we sprinkle in a fine layer of crushed mica to make the glittery bits. Getting them into the passages without scratching them up is a bit of a challenge, and making them fit so that they look natural can take days, but it's well worth it to watch the geologists come up with their explanations for these things.

Oh, wait, was that one of the secrets we're not supposed to tell? :big grin:

If they glitter, this is probably macrocrystalline calcite.

"Macro" means large, as opposed to "micro", which means very small. So, the large crystal faces do a great job of reflecting the light. Always very pretty to find macrocrystalline calcite.

Well this cave is full of white glittering formations in this area. One part even has tons of white glittery "sand" looking rimstone dam's that are about 1/4" thick and up to 8" tall. I've never seen anything like it.
