- Paleoclimate of Southwestern China for the past 50,000 yr inferred from lake sediment records (1)
- Long sediment cores from 2 lakes in Yunnan Province were used to infer the paleoclimate of southwest China over the past 50,000 yr. Magnetic, sedimentologic, and geochemical analyses on these sediment cores were conducted.

- Sediment cores collected from the southern basin of Lake Titicaca, on a transect from 4.6 m above overflow level to 15.1 m below overflow level are used to identify a new century-scale chronology of Holocene lake-level variations. The results
- indicate that lithologic and geochemical analyses on a transect of cores can be used to identify and date century-scale lake-level changes. Detailed sedimentary analyses of subfacies and radiocarbon dating were conducted on 4 representative cores. Several

- A 4000-yr sediment core record from Lake Salpetén, Guatemala, provides evidence for Maya-induced forest clearance and consequent soil erosion between 1700 cal yr B.C. and 850 cal yr A.D. Radiocarbon ages of wood, seeds, and charcoal support an age
