:) :D :P :)
Can you tell me what this is?..........

That kids toy called SLIME.... :D :D

im going to guess serpentine

Serpentine has a more crstalline structure.

CLUE:
This specimen will glow under ultraviolet light and produce a unbelievable color.

Clue # 2
The waxy surface

jade??

found this online when comparing...

Sorry Redpaw...... :P ....This one doesn't glow under ultraviolet light.
And its not Jade Kriss..

I'll give you a Clue.
This specimen usually grows in grape like clusters....
This one is just cut in half lenght wise, thats why the bottom is flat.

Is it vegitable or mineral? <_<

is it a "ide", "ate" or "Ite" or "ine"?

What does it streak?

Whats the hardness?

does it cleave or fracture?

talc?

serpentine is a good guess, it forms in dull or silky masses, is that right?

malachite?

when you say "grape like clusters", do you mean a dendritic formation?

I thought for sure it was Green Flourite.....

and looking at it closer I'd say Olivine now, but it doesn't appear to have the clarity of Olivine either?.

peridot or olivine are my last 2 guesses...I'm goin nuts here trying to figure this one out!! hahaha

sure has been a learning experience for me though!! thx Denise!!

Kriss

Those are all good guesses.........but not correct. ;)
OK Sammy, I'll give another Clue

It's an "Ite".. :D

Calcite?

I'm used to seeing calcite in clusters such as "dog tooth calcite"....but calcite covers alot of turf...just a wild guess...I only know about black and silver and gold and red rocks<grin>

I have a confession to make, however,
when I first saw it, me being from an ocean lined "beachy" state, my first thought was petrified whale boogher...don't know if I can say that in polite company or not, here tho'...

<_<

is it a limestone stalactite?

These are some great guesses folks.
Sorry Sammy, not a limestone stalactite.......... ;) :)
Sorry Tutor but not Calcite either, but wer'e in the right family with the "ites"....... :)

CP

This is driving me nutso!!

pyromorhite or wavellite?? ;)

You are coming up with some great ansewers Kriss, and some that look really look close to what we have...........but still not it...hehehehe :P ....guess I picked a good specimen to use. Keep guessing, you all are getting close. :D

Hmmm,
Is it kryptonite? QJ

Thats it! QJ's got it. :D
Thats why Redpaw is staying away from this one now. :D :P

Funny QJ......but keep guessing.
:D

K, I'm gonna throw a clue in here....... ;) :)
We know it's an "ite", so ......... check through the "P's" <_< :P

CP

Prehnite aka:

Ca2 Al2 Si3 O10(OH)2, Calcium Aluminum Silicate Hydroxide???


I give up...you don't know how crazy this is making me!! hahaha :P I sure am learning alot about minerals though...and thank you for that!!


Kriss

And all that learning payed off...........Good Job Kriss!!!!
You guessed it right. :D :D :D

Identification: Cannot be scratched by a knife; brittle; cleavage good in one direction, poor in another;uneven fracture;translucent to almost transparent. Crystals orthorhombic, rare; more commonly seen in botryoidal masses; radially fiberous.
Color: Light green, gray, white, colorless.
Environment: In cavities in volcanic basalt rocks; commonly with calcite and pectolite.
Occurrence: Fairly common in Connecticut and Michigan.

Now lets see if you can get the next one also. ;) :D

Great Job Kriss,
That was a hard one to figure out, I think maybe the blurriness of the picture was throwing us off, or maybe its just my eyes lately.

hey I also have an idea, not only could we try to find out what it is but also what geologic time period it was introduced. ? Just a thought..
NEXT !!

Everything I learned about Prehnite today: (copied and pasted of course!! lazy me!) :D

Prehnite
Location: Deep Sahara, Morocco: Djbel Melh, Bou-Arfa.


Prehnite was named after its discoverer; Colonel Hendrik von Prehn and is an attractive collection mineral that is occassionally used for ornamental stone purposes. Its color is usually a pleasant green and is at times quite unique to prehnite. Typical prehnite forms rather thick crusts with a rough or crystaline texture. Epimorphs (crystal growth over the surface of another mineral) over laumontite crystals are interesting and attractive. Usually the laumontite has dissolved away leaving the hollow crust of prehnite behind.

Prehnite is often found with zeolites and is sometimes thought of as a zeolite. But zeolites are actually tectosilicates and prehnite is a member the Phyllosilicates Subclass. However, like zeolites, prehnite can give off water when heated, but can not gain the water back like they can. Like most zeolites, prehnite is formed as a result of low grade metamorphism usually from hydrothermal solutions. Crystals can be found in cavities of mafic igneous rocks.

Minerals that can be confused with prehnite include gyrolite, smithsonite and hemimorphite. Prehnite is harder than all of these and lacks smithsonite's unusual luster. Hemimorphite is usually blue and gyrolite is not as glassy. Prehnite can be associated with many beautiful minerals and can make a fine specimen on its own. Its color, luster, associations and crystal habits make it a joy to own.

PHYSICAL CHARACTERISTICS:

Color is usually a pale green to a yellowish grass green, also gray, white or colorless.
Luster is vitreous to waxy or pearly.
Transparency: Crystals are transparent to mostly translucent.
Crystal System is orthorhombic; 2 m m.
Crystal Habits include nodular, concretionary, radial, encrusting and stalactitic formations among other similar types. Tabular or pyramidal individual crystals are rare but some nodular specimens show tabular crystal protrusions. Epimorphs (crystal growth over the surface of another mineral) over laumontite are usual, but available (see above).
Cleavage is good in one direction (pinacoidal).
Fracture is uneven.
Hardness is 6 - 6.5.
Specific Gravity is approximately 2.9+ (average).
Streak is white.
Other Characteristics: Lacks the luster of smithsonite and cleavage surfaces are curved and pearly.
Associated Minerals include datolite, gyrolite, fluorapophyllite, quartz, calcite, copper, pectolite, stilbite and other zeolites.
Notable Occurrences include the type locality of Cape of Good Hope, South Africa as well as Connecticut; Pennsylvania; Patterson, New Jersey and Centreville, Virginia, USA; Bombay, India; Harz Mountains, Germany; Austria; Scotland; Copper Valley, Namibia; Jeffery Quarry, Asbestos, Canada; China; New South Wales, Australia and France.
Best Field Indicators are crystal habit, color, cleavage, hardness and associations.

I told Bill that you all are driving me crazy with these "whats this?" posts but I love the learning...he said "you crazy? you're driving me crazy trying to find the right answers and I have to live with you!!"

It was fun, thanks again!!

kriss

Here is a good pic of prehnite.

That was a hard one, good job.
