I just watched a show that talked of the Myan's (Montezuma's venture north) and they say the blue clay was/is reserved for Mayan's Royalty and some petroglyph's have the blue clay on them to show royalty.
Hi, im new to this post so if I repeat what has already been stated or is known commonly please forgive me. Here goes..
hmmmm
that is very interisting.
there is a dike of what we thought was kimberlight up stream, in the center of the crator, unfortunitly its burried now, thank you loggers.
whats intristing is we pann fine gold about 1 km down stream from the end of the blue ground where the bedrock is exposed.
the gold is very course, but what is odd is the "pink sand "we get. it has very heavy quartz looking crystles in it.
have a look.
Im going to pop in some points that should be said first up.Hi, im new to this post so if I repeat what has already been stated or is known commonly please forgive me. Here goes..
Ive been in the diamond explorartion corner and are currently following a blue clay find here in Australia. So im interested inresearching is there an overlap.
Ill start by hitting known points of others that have posted here
1 magnetite.. magnetite is a common morphology of altered olivine. Olivine being one of the largest by proportion indicators for diamond, howevever the first to alter. The high magnesium content of olivine often gives magnetite cores or spinel cores in the matrix. Olivine also pseudomorphs into blue ground, kimberlite into clays.
Im kooking at your pictures of "pink sand" and although we shouldn't say untill viewing through a microscope. This looks like classic "diamond indicator minerals" (kims) for short. Im seeing "picroilmenite" and/or chrome spinel/chromite. small reds could be pyrope garnet., and pinks eclogitic garnet (classic colours) also although its not clear there are some clear crystals that match diamond crystalography/morphology (tetrahedronic) your showing what looks like (but is unchecked) classic KIMS minus purple garnet, but they are not essential. Im not used to typing into a scrolling page so im going to break this now read what ive submitted and begin a new reply with more if allowed. Much to say regarding blue clay and kimberlite/lamporite
Lastly (for the moment) im finding blue clay dykes and pipes as a by product of "shear zone" "greenstone" complexes. So these finds of "metal" state mineral (also packaged as chlorides, nitrates ect) are just simply the tiny volume of mineral that made it to metal state. The rest being held and unidentified as sulphide deposits (look up kalgoorlie golden mile or any greenstone gold deposit) pics time this is some of what im tracking/sampling the close up blue crystals are in hand sample to test for silver chloride. Lead could possibly hide as blue also but is less likely in this scenario. Pic 3 is one of the big fellas around here and on closer view it is also dark grey/black. Silver also turns black in chemical state in the presence of light. Last few pics are of diamond morphology. Which is the alteration of diamond crystal altered and resorbed from the chemistry and heat of ascention in the kimbelite pipe. I must note that the previos pics posted are definitely not diamond. Surface "tetrahedrons" or "macles" shapes in any firm are what your primarily looking for initially. But they dont have to be there.

Right, good point but im trying to direct this member how to check what he has and whyJono...great ideas, but I think starting a new thread would be best.
Id just like to add that although this is generally known as true it no longer holds. Argyle mine in Australia is proterozoic as are many greenstone belts. Both paying kimberlite and lamporite can be found off craton (off archaeon)Tuberale brings up an interesting point. I have only recently studied diamond prospecting, but I found this map on the Colorado prospectors forum which shows where the economic diamond deposits are found.
So far, economically viable kimberlite bearing diamond deposits have only been found in the Archons.
