well, nearly. mrgreen http://www.livescience.com/technology/070424_kryptonite.html Read about this and thought it was pretty cool so I'm sharing. As the Article reads the only Diffrence is that it doesn't contain flourine and isn't green, it's instead white and powdery like talc. And Because I absolutley love minerals, I was curious as to how many other people love minerals too. And Heck I just wanted a general thread about Geology. So I suppose I'll start. As said, I live in Colorado, and a couple weekends ago my family and I took a vacation to Creede and Lake city Colorado. On our way there though we drove through a couple of extinct Calderas and and other extinct volcanoes. It was pretty cool, and I knew this region to have been extremley volcanic at one point in time, and even if I didn't know before hand it would have become pretty obvious as we drove past the spanish peaks seeing the old Volcanic Necks and ridges which even converged into the current mountains there. But I was Surprised to find all the fault activity of the area. once we had driven past the Rhyolitic formation of the spanish peaks and other small mountains around the area I began to notice lots of fault movenment had happened here, so much so that some of the rock formations were nearly vertical and sometimes atleast 80 degrees backwards on a tilt. And at the end of that particular small mountain range I had notice that there was a huge horizontal s-shaped curve that just came to an end, no more rock. I then realized that we had driven through some Fault block/syncline mountains. It was cool, because you could just see where the break(s) had happened. Also while I was in Creede I learned that the area was actually due for a major earthquake. Made me a little uneasy at first. But it was all cool for a geology nerd like myself. question Anywho, my Question is this I suppose, does anyone live in a geologically active area? Or an area that was once Geologically active? If not, maybe somewhere that you have visited to, such as crater lake, south dakota, or Yellowstone national park? idea Side notes: Colorado's state mineral is Rhodocrosite. Colorado's state rock is Yule marble(all thanks to a girlscout troop, I don't know why they didn't just make it pikes peak granite, a pink granite high in it's potassium Feldspar content and unique to Colorado area.) Are there any other state minerals or rocks that would be interesting?

tiki_boyX2 it doesn't contain flourine Nothing contains flourine! Flourine does not exist! The word is fluorine; remember it. (Sorry if this seems a little jumpy. 'S a pet peeve.)

Ah no worries. mrgreen Are you at all one for Geology?

I enjoy Geology, I've only taken some core basic classes.
I was thinking about majoring in it, but decided to go with Multidiciplinary science instead.
I don't (really) know of any geologically extinct active area's in my city.
There are no active volcanoes in Texas but extinct volcanoe do lie along the Rio Grande rift system in west Texas. Volcanoes from the late Cretaceous period.
We studied Texas geology in my Geo class some last semester, but I unfortunatly didn't pay too much attention. I do remeber that Texas has undergone a long and dynamic history of igneous activity, structural deformation, and sedimentary processes which includes;
uplift of mountains, inundation by vast inland seas, river transport of large volumes of eroded sediment, volcanic eruption, and earthquake activity!
There is a fault here in my city, it's a small fault to the west near the southern end of the San Antonio. Which is probably cutoff's of a bigger fault line.
Another that I know of was right across the street from San Antonio Comunity College; The San Pedro Park Srpings.
Which was severly disturbed by people in the late 1800's. In 1899 it began to be 'protected' and refurbished.
I belive that springs are associated with faultlines, so I guess there is(are) a 'active area (s)' in my city.

I also learned that Texas get's the most amount of Tornado's per year!
Crazy!
More than even tornado state, which is Kansas right?
One of those.XP
But since we are such a big state, Per square mile Kansas actually get's more tonado's therefor being #1 in Tornado'ss.

^_^Well, not always, but are you talking about hot springs or normal natural springs? Normal natural springs is simply a spot where groundwater is escaping outside through a permeable rock layer, and it could come out of pretty much any permeable rock, and fault lines may be the reason as to where the water is coming out, such as a large displayment by fault movenments, but other wise Springs don't always point to active fault lines....or even fault lines at all for that matter. I am most definantely glad to hear of those springs being prtected though. I know there's a spring about 2 football fields away from my house that leaks nice fresh safe mineral water from the Aquifer that my house is built on. It tastes good. mrgreen I am curious as to one thing though, next time you see an area of ground lifted up above the the rest of the ground so you can see rock layers, do you think you could look for a thin, maybe only a couple inches thick, line of sediment between the rock layers? Oh, and another note, if any of you have heard that pikes peak was once a Volcano, dismiss what you were told, it was not a Volcano Exactly, it is something called a Batholith, a cooled magma chamber that has been raised above the surrounding area by possible tectonic forces/erosion of the surrounding ground. So pikes peak is just a big thing of Granite high in it's potassium Feldspar content.

Oh well they are deffinatly not hot springs, I don't think..maybe warm springs.
lol
The water is warm.
I remeber mention of a faultline there, but I perhaps it is inactive.
Although I can recall my professor mention that "quakes" do happen but they are sooo minor that they are not felt at all.
Next time I go out there, I will take my camera and take pictures and explore the geology of it!

and I can vaguly remeber something about PIke's peak.
I do know it was not a volcano, it was a batholith, that does ring a bell.

That's good to hear that you know it's not a volcano.I have a bad habit of correcting people on that at times. xp So I just read about this interseting Mineral Discovery in my Pop. Science magazine. It's about The largest known Mineral Crystals of Gypsum that have formed some 1,000 feet below the Chihuahuan desert in a cavern. The Crystals are about 60ft. long, and 3-5 ft. wide. They probably formed from hundreds of thousands of years immersed in mineral rich water at a steady temp of about 136 degrees F. Unfortunately I couldn't find pics on the internet though. cry

That's interesting.
Is that the bigget find on Gypsum?
It's hard to find some good pictures on the net generally.
You always get all this other random spam.

heh, yeah darndid spam.
Yes they are the Largest Gypsum Crystals in an area of about the size of a basketball court. And of Course they are the largest mineral Crystal Structure Found too. Gypsum may be common but it's still a pretty cool thing to see.

Oh hey! I found a pic, it's not the best pic, and it's not a pic of the largest ones, but it's still cool.

Isn't it? I want to go there sometime and see them for myself. and I also want some Lepidolite, which I may very well get this coming weekend.

OMG!
I would love to see that personaly.
It's just so unbelievable.
Is this underground?
it bewilders me how they got such a clear picture... or maybe just because it's white. xp
it makes me wonder how...did they get down there.
How deep in the ground is this?
