Is there anything else worth pursuing in geology besides petroleum? I mean come on… I'm pretty sure we are all doing it for the money.

It's not just iron we are talking about here.

Iridium. Osmium. Platinum. Gold. Rhodium.

All of these are contained in these asteroids, and while, yes, it would be incredibly expensive to mine asteroids and other various rocks suspended out there, but eventually we will become desperate enough for them.

And that's where pursuing a degree in it becomes handy. We would need people educated to devise a way to make inter-planetary mining feasible. People with degrees in geological mining/engineering, astronomical engineering, and so on and so forth.

I'm no expert on this, me being a humble vulcanologist wanna-be, but there is a lot appealing about mining the stars. . . err planets.

Geodude 04/05/15 (Sun) 07:38:45 No.253

>>252
Asteroids are mostly composed of iron, mining trace elements like the ones you mentioned would be even more difficult.

You would need something like the USG Ishimura from Dead Space, a massive mining ship with all facilities on board, minus the necromorph aliens. Before we have a ship like that, we need a power source for the ship that would be both quick and efficient.

Would take at least 50-80 years before we come up with something even close to that. Then we would need to design a ship for mining that would be hugely expensive and require a permanent crew, for the purpose of harvesting minerals on other planets or asteroids. The mere operation of this spaceship with everyone involved would probably be worth more than the value of whatever you're mining, unless we discover some super secret substance that is more valuable than anything we have today.

As science-fictiony as this sounds, that's the reality of interstellar mining. The only other alternative would be to redirect these asteroids so they crash into Earth, but as a geologist, you know how well that will turn out.

Colbrik 04/07/15 (Tue) 01:55:13 No.254

>>253
Yes, I can understand that crashing asteroids into Earth might be a bad idea, and am fully under the assumption we might not want to do that. And yes, it would be incredibly expensive and take several decades to maybe even grasp something that might make this entire endeavor feasible. But that can only come with people actively looking into it, people who studied what it would take for it to be possible.

Now I'm not saying that if we have people with interstellar mining degrees that we will have a solution readily made, but it is just something to possibly look into. Maybe as a hobby or a part time job. If someone does find a way to make it feasible, imagine the money that could be generated (and by feasible I mean find a way to get the ship, equipment, and fuel into space, mine and process the ore, and send it back to Earth). Maybe the grandeur illusions of a hopeful, but I think it's worth at least a shot looking into. If it works out, great! If not, at least we tried before dismissing entirely.

Made of magma and hot rock (Asthenosphere), pending a sudden disappearance of the lithosphere.

Question About Research From a Layman Geodude 06/10/15 (Wed) 07:21:01 No.268 [Reply]

Alright. I always had a passion for geology. I think it's pretty cool. So cool that sometimes I queue up Google earth just to look at random land forms and other such things, then read about them.

Today, I stumbled onto pic related; the Christiana Island chain, north of Crete and a bit southwest of Thera (Santorini).

I've been searching for the last goddamned motherfucking hour and I can't find shit for dick beyond (paraphrasing). "Shit is rocky as fuck all around it, so only fishing boats are allowed all up and around it." "There was a settlement on this shit heap, with pottery unique to the region! Even a mine! Oh, and, surprise surprise, they packed up and left with the Thera Eruption." There's all these great curious little tidbits here, /geo/, but there's nothing substantial. ""FUCK""

Alright, so the long and short of this is; whose dick do I have to suck to get more detailed information regarding geological surveys and archaelogical studies? Because holy shit man, I can't rest now. I gotta know more, man.

Geodude 06/10/15 (Wed) 07:51:40 No.269

Also, if somebody can point to a place where I can me detailed topographical maps of the Mediterranean sea floor, I'd be very appreciative.

You'd probably have to look at more regional stuff, as the literature for the particular island would most likely be in Greek or whatever.

So, If Ice is crystalized water.

Ice is a mineral?

If Ice is a mineral, than water is molten mineral.

Water is molten ice.

Water is lava.

We live on a planet where lava falls from the sky and makes up most of our bodies.

Geodude 05/15/15 (Fri) 15:06:10 No.264

In geology, plenty of exceptions are made for water that are not made for any other compound in terms of chemistry, classification and behavior.

While your line of thinking isn't necessarily untrue, its just not accepted in any academic setting because by your logic, any liquid composed of a molecularly homogeneous structure is a "lava", even if its at room temperature. Mercury liquid at room temperature? Lava. Almost any liquid can crystallize when brought cold enough. If you melt sugar down to form caramel, that's lava too.

Magma is considered mafic, felsic or something in between. Water is neither so it isn't magma or lava.

Not really, a lot of people fail calc 1 in my school, or in general. Its one of the classes with the highest failure rate because a lot of people aren't good at math, so they have a hard time wrapping their mind around limits, integrals and derivatives.

I remember when I took calc 2. I got an A in calc 1, but that was 3.5 years prior to having taken calc 2 which is a much more rigorous course. I didn't know I needed calc 2 until I realized its necessary for grad school, and I managed to squeeze out a B+ in it after nearly driving myself insane because I forgot all of calc 1 and had to reteach myself everything.

I talked it over with the professor, and have till this weekend to decide if I'm dropping it or trying to pass. I'd need to get at least a B on both the next midterm and the final. At least if I drop it I can sit in for the rest of the class.

I don't know geos. Maybe I should re-think my life or something. I can understand geology quite well for as far as I've gone. Even to the point where I can teach the basics. But I can't break though this stupid mathblock.

It was nearly impossible to book a hotel because as they put it, there is "unprecedented interest". I mean, its Mt. Washington after all.

I'm going with some colleagues so I'll take a bunch of pics and post them, and tell you about any interesting presentations. My research isn't ready to present so I'm just gonna observe. The national GSA is going to be in Baltimore in the fall, so west coasters are out of luck for that one too, but last years was in Vancouver and the one before that, in Denver, so you had your fun :)
