摘要：

Sierran rivers that discharge to the Lahontan basin have much lower (similar to 4.5%) delta(87)Sr values than the Humboldt River which drains northeastern Nevada. The delta(87)Sr values of tufas deposited during the last lake cycle were used to determine when Humboldt derived Sr entered the Pyramid Lake subbasin. Prior to similar to 15,000 yr B.P., the Humboldt River flowed to the Smoke Creek-Black Rock Desert subbasin. During the recession of Lake Lahontan, the Humboldt River diverted to the Carson Desert subbasin. This study has demonstrated that Sr-87 can be used to determine drainage histories of multi-basin lake systems if the delta(87)Sr values of rivers that discharge to the basins are sufficiently different.
