Stop it. You keep throwing down these challenges as if YOU are some sort of expert on this stuff. GIve me a break. Poser.
ARe you fucking kidding me????
Extrusive: extruded onto the surface. (Rhyolite, Andesite, Basalt) (Felsic-->Mafic)
Intrusive: doesn't make it to the surface (Granite, Diorite, Gabbro) (Felsic-->Mafic)
(There's also hypabyssal but you wouldn't have heard of that)
Did I pass the test?? Or do you want some much more detailed igneous petrology?
Why don't YOU ever have to show us YOUR knowledge? Oh, yeah, I know...you are a fake.
Why don't you tell the class what the difference is between FELSIC and MAFIC? (get googlin')
What is your problem? Is this some sort of stupid game?
What a joke.
No, you failed. The main differences between them is the size of the crystals. That is due to time.
Intrusive get to cool over millions of years so their crystals are large. Extrusive, on the other hand cool rapidly, so their crystals are small.
There is little mineralogical difference between a rhyolite and a granite. The only major difference is the size of the crystals.
Junior.
Like I said. You don't even know the basics. You cut and paste from geologic web sites.
That makes you a moron.
