Abstract

In the anoxic Cariaco Basin of the southern Caribbean, the bulk titanium content of undisturbed sediment reflects variations in riverine input and the hydrological cycle over northern tropical South America. A seasonally resolved record of titanium shows that the collapse of Maya civilization in the Terminal Classic Period occurred during an extended regional dry period, punctuated by more intense multiyear droughts centered at approximately 810, 860, and 910 A.D. These new data suggest that a century-scale decline in rainfall put a general strain on resources in the region, which was then exacerbated by abrupt drought events, contributing to the social stresses that led to the Maya demise.

5. Analyses for the Holocene section at 2 mm resolution were obtained with a profiling x-ray fluorescence scanner at the University of Bremen (4). The Ti element mapping at 50 μm resolution was carried out with a Röntgenanalytik Eagle II MicroX-Ray Fluorescence system at ETH Zürich (with the use of an Rh tube at 40 kV and 800 mA). The sediment slab samples from hole 1002D were measured in two parallel and overlapping line scans (sample length 15 cm). For optimum counting a measurement time of 24 hours for each sample slab was applied.
