Ar/ Ar Hornblende Evidence for History of the Laurentide Ice Sheet During the Last Glacial Cycle... 

The history of the northern hemisphere ice sheets is an important aspect of the paleoclimate system. The layered record of IRD and other climate indicators preserved in deepsea sediment cores provides the potential to unravel the sequences of events surrounding important intervals during the last glacial cycle. Results of an extensive campaign to analyze the " Ar/ Ar ages of multiple individual hornblende grains in core...
