Full Description

Göbekli Tepe (~9,500 BCE), Giza (~2,600 BCE), and the Maya Yucatan sites (~600 CE) all use calcite limestone (CaCO₃) as their primary building material and substrate. These sites span 12,000 years and three continents. Calcite limestone has a measured piezoelectric coefficient (g_eff ≈ 2.5e-3 V·m/N), is acoustically competent (Q = 50-200), and when coupled with water creates measurable electric fields through the piezoelectric effect. The repeated selection of this specific material — rather than granite, basite, sandstone, or earth — across millennia and continents suggests the material was chosen for its functional properties, not merely availability.
