12-Ilmenite crystal (A), framboidal pyrite (B) and rare (titano-) magnetites bubbles observed on background stages (V,II,I).Comparison between typical magnetic crystals found it in background stages (V,II,I) and peaks stages (VI,IV,III) (D, E). Background zones are dominated by the presence of ilmenite crystals or (titano-) magnetites affected by dissolution and peak stages (VI, IV, III) by mostly well-preserved (titano-) magnetites with octahedral shapes. Blue circles indicate X-ray spot element analysis.

The relationship between climatic-environmental changes and the cultural implications in
the Northern Mesoamerican Frontier is poorly understood, because of the lack of highresolution
well-dated paleoclimatic-paleoenvironmental records. In this work I present
high-resolution paleoclimate and paleoenvironmental reconstructions of the Northern
Mesoam...
