Analysis of sedimentary environment of core AB-67 at Barrow

摘要

A total of 48 samples from the core AB-67 at Barrow are analyzed for 25 grain size items and 44 geochemical items. Q-mode factor analysis applied to these data yielded 4 factors. Mapping of there factor showed their close affinity to sedimentary en- vironment; these core sedimentary rate, precipitation, sea level change, annual tem- perature. Paleoenvironmentary transfer functions were defined to estimate mean annual temperature and annual precipitation from corelationship between 5 samples at core-top and observation record form Barrow Meteorology Observatory.
