A Type Of Volcanic Rock ??

[Cariboo5]

Found this in a little creek, several of these were scattered through out the area. Very light and the color is as shown. This area is known for volcanic rocks but I don't know what this is called. Any help is appreciated... Thanks

Hi Cariboo5, If I found this, Especially in Canada, I would be Soo Excited! This could be a Kimberlite/Lamphorlite "Bomb". These rocks are blown out of Kimberlites which are carrot shaped volcano dykes and could be an indicator of Diamond ferrous Kimberlite. These rocks don't travel too far from the kimberlite so you could be within a one mile to a mile and a half circumference of a Kimberlite! Look for Diamonds! and pyrope, Garnets! etc...Look up what rough diamonds look like and the many colors.

Use Google Earth to search your area and look for "Blueish ground" and paths where there is no vegetation (the soil around a Kimberlite isn't conducive to grow trees) and look for small round "Lakes" with a whitish ring around the beach area. It may be filled with water (the center) or not.

In the State-Line district of Colorado/Wyoming alone there is said to be 2000 Kimberlites that are unexplored! Canada is recently becoming the Top 3 producers of Diamonds in the World...Wow!...Have fun hunting and Good Luck!

I would be guessing Pumice or tuff.

Minergirl & Eu_citzen thanks for the input. I will definetly be going back to the area to do more exploring, gold pan testing etc. This is in the Cariboo region of BC which started the gold rush in 1858 and by doing research I found this is called the Quesnel trench which is also known for its volcanic rocks. The closest known area for some diamonds from here is about 150 miles south. I will be looking for the indicators you mentioned.

Just a few hundred yards from the little creek and what seems to be out of place are huge rocks (bolders) in a draw that spans about 250 yards long. For miles around there are no bolders like this any where... I think these probably were deposited here by glacier action (glaciers moved through here from the south-east direction)

Pictures attached of the huge bolders...Thoughts on how these bolders got here?

Hi again, Nice pictures and seems very promising for Gold after reading about this area. Possibly this is an "End Moraine/Terminal Moraine"? I'm including a link which explains.

Illustrated Glossary of Alpine Glacial Landforms - End Moraine

Many of the Famous Diamond finds in Wisconsin and other Mid-west states have been found at "End Moraine" sites. (27 Carats..etc) All thought to be brought down from Glaciers from Canada...however, there are many Kimberlites in Wisconsin/Michigan...Kinda explains why DeBeers has leased Hundreds of acres in the Michigan UP. I think any End Moraine is a good place to check for your Gold and Diamonds. Alot to absorb and the study can be endless. You also want to try and pinpoint which glaciers brought down the gold/diamonds and then which glaciers may or may not have dropped a hundred or 200 feet of glacial till on top of Them...Thats why End Moraines are good search areas. So you can look for Drift Diamonds/Gold or those Kimberlite "Bomb" rocks...those generally will disintegrate quickly when transported any distance, so when you find them, I think you'd be close.

MinerGirl Addition to my Post...I woke up this morning and the first word that popped into my head was "Cinder-Bomb"...Ha..Thats what they're called! It was bugging me for days now...

I agree with MinerGirl, End moraine seems plausible.
