I found a novel specimen of Quartz Fractured by I believe a fault line, was just wondering what other stones or minerals I might look to find in the Area, since the nearest known Quartz vain is about 150, 300 Mile's away this is an unrecorded and unexplored find, thank you. Oh all the Fools...

Soo, 6.4 earthquake yesterday, 7.1 today. Tomorrow will definitely be 7.8. I mean that's just science.* Hope everyone is okay. Fortunately people in the area have some experience with these things. *This is in no way science.

The past few years scientists have been finding evidence of a huge subterranean biosphere. Reminds me of the new nematode found in that South African mine a couple years back. If we find no life on Mars we should consider digging. :)

By dust I mean fine particulate matter, and I'm interested in natural sources, here on Earth, but also on the Moon, Venus (if there is any), Mars, etc. Focusing on the main sources, both immediate and indirect. And ignoring "water dust" (i.e. snow and ice), at least here on Earth. My guess is...

This rant was motivated by the rock and roll of a 4.8 Magnitude earthquake on 7 December 2013 . In the New Madrid Region they are using the ongoing earthquakes to image the mantle plume under New Madrid. Earthquakes, as seismic energy sources, can exceed the power of 1000's of pounds of TNT...

Did the Earth give birth to the Moon in a nuclear event as hypothesised here? For the mentally challenged, in words of one syllable, what is an 'isotope'?

Short but interesting just out today (and apparently it has not been entered here yet - apologies if it has) but I have not seen it: http://www.livescience.com/28401-north-america-geology.html

If I understand basic geophysics correctly, the inner parts of the Earth can be divided into the mantle, consisting of rock, and the core, consisting of iron and nickel. The reason that the iron and nickel form the core is simply that they're a lot heavier, so they've sunk the deepest. What I...

I grew up with the idea that the area west of the San Joaquin Fault would eventually split off and become a micro continent. But lately I've stumbled upon the idea that this might not be so. That the rift might actually be further east in an area known as Walkers Lane of which Death Valley...

The discussion about whether or not there was a global flood as described in the Bible has been split to its own thread here from its original location in the Biblical Fallacies thread, located here. There was a global flood?

Incredibly I got into an argument with someone over the number of continents. It started off as a discussion over where the Olympics should be held in 2020. I said it could be anywhere but South America but this other guy said North America should be off limits too because both are just one...

Greetings. This thread is aimed at geologists, explorers; cavers; divers, hydrologists, and the merely curious amongst us. I've had a near obsession with first-magnitude springs for decades. There is something fundamentally alluring about huge gushings of fresh water. Springs are one of the...

Way back in college I took a class on physical geography. At one point we were talking about the geo-physical history or North America. I remember one of the things that captured my imagination was the idea that some think at one time North America had an enormous mountain range that ranged from...

We all know the story's basics: Alfred Wegener proposes the idea of Continental Drift to explain a great many things about geology. Skeptics challenged him to come up with a mechanism for how it worked. In this he failed (or got bored and went to other things) and the idea languished. Until...

I'll admit that I find the idea of mantle plumes driving tectonics to be quite interesting. And I love this place www.mantleplumes.org because I can go through journal manuscripts for free. So does anyone have any knowledge to share? I know we have some geologists here. Are they real? Are they...

In a school there is a geologist with an office. In that office there is a desk. A desk that seems just like so many others; with a cherry stained wood, hand crafted drawers, fingerprint smudged handles on those drawers, a top covered in papers and a seemingly field work abused laptop. But on...

How the Earth was Made - great series. I'm recording them on DVR. Right now I'm watching one on the Birth of the Earth. I was always interested in astronomy but hadn't kept up with it. I had heard that the current theory was that the Moon was formed from a collision, but this program explained...

....and then I read the end.:D http://www.icr.org/article/2830/ It seems the Genesis Flood can account for anything.:rolleyes: Five Schrute Bucks to anyone that can link celebrity dance competitions to the flood.

From The BBC. I was completely unaware that comparatively tiny human efforts such as drilling could potentially trigger something this big. I was also hitherto unaware of the existence of mud volcanoes.

I'm a bit puzzled about how much is known about the conditions on the early Earth before any life arose? Was Stanley Miller close to the truth? How much do we know currently, is it controversial? I'm once again getting lost in the information and looking for a short cut before getting my hands...

My wife just sent me this link on YouTube, and I felt that I should share it with you all... http://youtube.com/watch?v=7kL7qDeI05U I cannot begin to say how stupid this idea is - for one thing, where the hell did all the water come from if the planet has been expanding as they claim? As a...

Mods, please feel free to move this to the community forums if it is better suited there. I'm just wondering if any JREFers will be attending the upcoming GSA cordilleran sectional meeting in Vegas. Anyone, by chance?

Diamonds nearly as old as the earth.

PLEASE: Read the OP first. It occurs to me, seeing yet more fundies explaining why evolution is bunkum, that they come from the same pod as "No plane" CTists - lacking facts, behaving irrationally and refusing to accept evidence. Now, there are lots of places where scientific evolutionary...

I live just north of the mouth of the Columbia River, on the Long Beach Peninsula. The whole town is built on a big sand spit. The other day, I noticed something that really amazed me, and when I showed it to some other locals, they were amazed too. I had dropped a magnet on the ground, and...

Attention savvy JREF Forumites. Even if you're not a geologist you are invited to identify this odd rock. (The "Ironwoman" at MIT could do it in a flash I think, but she's busy with e-mail problems lately.) This was found in a streambed in Bucks County, PA many years ago. I first thought...

A rock that I found when I was a kid. You can read my other website on this specific rock. http://www.angelfire.com/magic2/mysteriousstone/ What could it be?... some say its a river rock.. some say its a meteorite that fell thousands of years ago ..but was smoothed out by water erosion...

People who work at the Grand Canyon have been ordered (based on pressure by bush and his crimninals) not to give an official estimate of the geologic age of the Grand Canyon BECAUSE IT MIGHT OFFEND ZEALOTS. "In order to avoid offending religious fundamentalists, our National Park service is...
