Data collected in Mongolia offers key clues to past climate



Located in the interior of the Asian continent, Mongolia lies at the northern limit of the Asian monsoon and occupies the zone of highest seasonal climate contrast on Earth. Sediment cores from Mongolian lakes contain crucial information about paleoclimatic variability from a region that is poorly understood relative to continental margins and ocean basins. As the locus of four very large (M≥8) earthquakes during this century, Mongolia is also a natural laboratory for studies of slip on active, intracontinental faults [see Molnar and Prentice, 1996].
