Neuquen Agates
North of Neuquen Province, Patagonia, Argentina, South America
 .
   Like the Marlargue/Puma agates, Neuquen Agates appear to be a type of concretion that were formed from water-expanded (or gypsum-expanded) fossil crinoid heads very similar to Indiana "Geodes", Kentucky, Tennessee & Alabama Agates. Neuquen agates appeared to be more weathered (rough surface feel smoother), and more varied in color such as white, gray, red, yellow, brown, and blue. Pink and black are rare colors while red, gray and  brown colors are more common. The interesting characteristic of some Neuquen and Marlargue Agates is that they contain multiple fractures that have been "healed" and bleached by water giving them a chambered look.
    Important Note! Often because of their similar appearances, the agates from Neuquen had been mislabeled as "Puma" Agates even the source of Neuquen agates is about 250 kilometers from where the Puma Agates are found (Marlargue). The differences are that the Neuquen Agate have wider variety of colors and contain quartz crystals that tend to take up more space than those of Puma Agates. The "Samtra" Agates may be actually Neuquen Agates coming fron Neuquen Province, not Mendoza Province.
