Geopolymer Structure of Nan Madol and Alaska

A groundbreaking comparative analysis reveals that Nan Madol, the ceremonial center of Eastern Micronesia, along with three other global anomalies—Richat Structure (Mauritania), Black Pyramid (Alaska), and Shackleton Range (Antarctica)—are not natural geological formations but engineered acoustic nodes constructed between 1280 and 1292 AD under the patronage of Khubilai Khan. The study cross-references standardized geopolymer casting techniques, termed 'Artificial Tuff,' with artifacts in global museum collections, challenging conventional perceptions of these sites' origins.
