• Archaeologists analyzed 788 obsidian artifacts from Templo Mayor, Tenochtitlan, using portable X-ray fluorescence (pXRF).
• The study traced the geographic origins of obsidian, identifying at least eight sources, including Sierra de Pachuca adn regions outside Mexica control like Ucareo.
• Green obsidian from sierra de Pachuca was preferred for ceremonial objects due to its symbolic value tied to mythology.
• Trade networks of the Mexica Empire extended beyond its borders, involving rival communities and operating through local markets rather than direct acquisition from mining sites.

Indian Opinion Analysis:

This research offers key insights into economic systems in pre-Columbian societies, emphasizing how trade influenced politics and societal structures. For India’s historians or archaeologists studying ancient economies such as those under the Mauryan or Gupta Empires, parallels can be drawn regarding long-distance trade fostering cultural exchange and power consolidation. Notably,shifts in resource preference due to centralization mirror instances in Indian history where empires standardized resources for religious or administrative purposes.

The detailed compositional analysis highlights how modern techniques like pXRF can uncover complex trade relationships extending beyond political borders-a relevant tool for tracing India’s ancient trade networks with neighboring civilizations such as Mesopotamia or Southeast asia.Practical applications include better understanding ancient logistics and resource distribution mechanisms vital for India’s archaeological pursuits.
