My favirote rock is Obsidian. Because its fast cooled magma, normally extruded underwater
My favirote mineral is Calcite, because it reacts with acid and is generally cool!

Jack

Probably shale because it can have cool fossils in it

Mine's got to be limestone because it hosts an amazing underground world.

Gus

Carboniferous limestone at the moment. I'm also pretty fond of lewisian gneiss.

Paleozoic Limestones, preferably in the Canadian Rockies.

Shap Granite, for no other reason than I get to go round singing "Shap! - Aaahhhaaahhh it'll save every one of us!" to the Flash Gordon theme tune. 8) I think I may have revealed too much... :oops:

Pumice is a cool rock coz it floats.

And it gets rid of hard skin on your feet.

And it's got little air bubbles in it just like Aero chocolate bars and anything that reminds me of chocolate is a winner with me.

I've always like granite, just 'cause it's pretty. I have a very nice piece of Scottish granite sitting on my shelf that I picked up when I visited the Solway Firth

Perovskite - Earth's most abundant mineral

... now if only if I could get my hands on some

"Rhyolite" ash-flow tuffs because that's all I'm really qualified to look at anymore and it hosts nice little gold ore bodies occasionally...thanks to Benhauld for finally revealing what those song lyrics were actually saying...I thought it was something like '...Flash, wow oh, master of the universe..."

My beautiful pumice stone..all light 'n' bubbly rockyness:

Maybe...gneises and schists, but quartzites and slates too, so I think that I should say that all the Metasediments are my favorites.

I'm liking quartz a bit more now, because i made two bits of it spark! its cool!

I made Gypsum on that last post! yay!

yay, I evolved into gypsum too, but only realised this morning!

Only another 4934 to go for me to get to diamond!

My favourite rock is granite, partly because Cornwall would not exist woithout it and I live there.

However I like schist and gneiss because I can use it to describe people and things.

i.e.

Please explain whatever i have done to you to use such descriptive language against me?

I dont think that its fair!

You havn't questioned the truthfulness though

I'm too truthful to do that!

fave rock is granite.

My favourite rock is a garnet mica schist. Good to look at in thin section!!

Very pretty!

Makes all those hours studying thin sections worth it!!

Might have to disagree with you there Nothing makes thin sections really worth it - the pretty colours are a distraction though!

Epidosite...maybe

Or not...

Whoohoo, I'm Calcite!!!!

Congrats! Me calcite too!

I think im going to have to go with basalt. Its pretty when its shiny black.

although im quite into finding some nice black shale with funny trilobites for me to bag.
