PICOS GRANDEHere's a new ( rendition ) what satellite maps are revealing of Ivana.
- massive river ( long ago ) atop bluffs
- most likely came from up north ( through current Picos )
- chewing apart Picos west shoulder creating rocks ( still visually seen )
- depositing sands and rocks forming Ivana deposit ( soft snd hard )
- Picos watershed tail wraps around Ivanas hard mound creating soft sand ores
- Ivanas mound could be hardrock or..... significant rock pile from Picos chewd out shoulder
- Ivana and Maria appear to have developed tails ( remnant rock and sands depositing )
- watershed may not have come from up north rather.... westerly into Picos
- Lower basin may have been a grester
Picos Grande Salar ( now dry )
- Some of the lower terrain in Picos Grande appears as smooth bedrock
As mentioned in prior post, Picos west shoulder is seeping mega green colors into Picos salar.
High odds it's phosphates.
Over the years of trying to learn geology i've come across paper speaking about calcium
turning rivers and lakes green.
Potassium 40 decays to calcium.
Potassium and Calcium are highly related.
Open in new window 
I'm surprized the huge fertilizer conglomerates are not in on the uranium phosphate action
in S America. Stellantis using the Thiophosphate tech = smart.
Lighter, more energy dense battery. And as most know what phosphate and potassium
contain - no surprize it has the density in mega energy.
If Stelantis is teamed with LIT - ( Grosso ) and if Areva was once in the mix with BSK )
Me thinks... Europe could be making a quantum leap in forerunning new tech using
thiophosphates.
CHIHUIDOS ( green flats ) ( bluffs appear bluish green ) I'll do a retake on what i'm seeing in satellite maps given i've learned a bit about
phosphates and potassium over the weeks of researching.
Even potassium can turn green.
Green everywhere....
including the dune open flat sands.
Colorado USA Green uranium bloom on rocks
Another uranium example green- fuzz bloom and crystal 
Argentine Cordoba uranium mine - rocks dev green oxides / carb atop surface Page 7 - green moss morhology ( certain vegatation love the phos / potass / uranium )
ever wonder why some clay farmland produces larger sized crops ? wink.
Page 8 -
6 o'clock position under word desposition ( under on letters ) = green rock
4 o'clock position from word San - 2-3 rocks morphing green.
Spot these two examples other green morphing rocks will easily be seen.

So... i've chosen to rethink the possibilities of.... Chihuidos.
Heavy dark greens everywhere. Rock sediments 150 thick and open flat dune sands.
Phosphates and Potassium contain uranium.
Which makes Chihuidos very compelling.
Does it harbor decent uranium grades ?
And of course the 12 km target SW of Ivana atop bluffs.
My new take ?
Basement rocks overtime -------> break up due to seismic subtle land movements.
Creating significant sm rocks all atop surface.
And larger massive rocks seen aside of bluffs slightly fractured.
= makes more sense it's surface basement rock as source.
12 km sw target from Ivana...
does show purple rocks converting to ----> green rocks and a fuzz atop green rocks.
mix going on.
Potassium and Phosphate morphing and vegatation growth becomes an
ideal pathfinder for ( elevated ) concentrated percentages.
Cheers....
