Where Subduction Faults Meet Super-Caldera Glass
Walk into any counter-lit stone and curio shop in San Marcos La Laguna, Panajachel, or Antigua and you are looking at the collision debris of three tectonic plates (**North American**, **Caribbean**, and **Cocos**) plus the 84,000-year-old **Los Chocoyos** super-eruption that carved Lake Atitlán.
Beneath the tourist labels lies an extraordinary xenomineralogical cabinet: rapid-quenched rhyolitic void-glass (**El Chayal Obsidian**), 23-million-year-old UV-reactive fossil polymers (**Chiapas/Highland Amber**), high-pressure subduction silicates (**Motagua Serpentine & Jadeite**), and hydrothermal copper-vein matrices (**Chrysocolla & Malachite**).
