Petrographical and Geochemical Features Coupled with Geophysical Observations on the Nazca Lines

A key discovery in the study of the Nazca Lines reveals that sediments in the vicinity are highly cemented by salt, likely originating from sea-derived aerosols. This process is linked to geological features and geophysical anomalies, particularly high sulfur content at the surface of electrical resistivity anomalies, suggesting cemented porosity in coarser-grained sediments. The research combines petrographical and geochemical analyses with sediment provenance studies, confirming that the sediments correspond to surrounding Mesozoic rocks. This interdisciplinary approach provides new insights into the geological processes shaping this UNESCO World Heritage Site.
