Kimberlite pipes Options

[leonard]

Here's a little item I found on another forum.

This thin slice of a kimberlite rock from northern Canada, seen through a microscope and in polarized light, shows colorful minerals caught up in magma that rose from deep within the Earth.

Astrobleme,

One of my young guys stumbled across this a few days ago... tested it. Diamondiferous Kimberlite exposed right on top of the ground.
Of course it is now claimed done and dusted.
Onward's and upwards!
Cannot wait to get my teeth stuck into this bit!

New to group and am hitting the ground running.

What I wouldn't do to get DD and Astrobleme in the same room give them a topic for discussion and then just sponge it all up. DD I spent two stints in Southern Africa. Once studying black rhinos in Namibia and again working with Southern Ground Hornbills in Northern SA and Kruger. I have friends that still live in fear because of the violence and land reparations. Seems like just about everybody loses out...the people, the land, and the wildlife...sad. A piece of me will always be in Africa and I can't wait to be able to go back.

But back to happier things, those "indicator minerals" on the ground in the second picture, is that what I think I've read other people referring to in other posts as lava ash? Is this correct? Are these like xenoliths or do they form in the kimberlitic process. I'm so new to this and have been just read, read, read, reading and hound, hound, hound, hounding. I'm looking for heavy and shiny things , but also keep anything that looks out of the ordinary along with location in case later if/when I learn more, I can go back to sites I may have been too ignorant to know they were good in the first place lol. This seems to be the case with these. I found very similar looking stones in the past but because of how far back in I'd hiked, I only took a few small ones and snapped a gps point. Now of course I can't find the stones I took, but I have the gps and I don't need it because I remember right where they were. Tell me if I'm wrong or over-simplifying but to me they felt and looked like green, purple, yellow limestone that got thrown into lava for a bit, partially melted, and then yanked back out.

Thank you so much and I look forward to learning more.

Musk Rat,
Welcome to the forum!

Well what you suggested has been done! Astro and I have met and been together in my truck looking at possible Kimberlite pipes.
Was great meeting the guy even though our trip ended up with no Kimberlites or indicators found. Cost me a pretty penny but that's all part of prospecting.
That trip I did manage to find a kimberlite pipe and managed to secure it.



Here is Shea one of my guys sitting on top of the exposed Kimberlite




When prospecting for diamond bearing kimberlites this is what you are looking for, G 10 Pyrope (fire) garnets and Chromium diopside (green) crystals.
These have been weathered out of the host rock.




This is what they look like still in the host rock Kimberlite.



And the real thing you are looking for!


Hope this helps!
PS the light green CR crystals are very brittle and only travel about .75 miles away from a pipe in a river setting, before its crushed to powder.
So if you find them you are close!

Diamond digger will you check out a post i put up on the member side? It's something I've found that I think is significant, but I'd like to know if you think the same.
