英文摘要: Current estimates of Moho depth in southeastern Australia are based on sparse sampling. The results are augmented with 180 new Moho estimates constructed from spatial stacks of crustal P wave reflectivity derived from autocorrelograms at over 750 stations. The spatial stacks of reflectivity are constructed using a Gaussian with half width 0.5°. Picks of the base of crustal reflectivity are made with the aid of the previous Moho model, based on the sparser data, and knowledge of the variation in the character of the crust-mantle boundary across the region. Good ties can be made to previous results from deep reflection profiling. The new information fills in many holes in coverage and provides a Moho map with closer ties to geological provinces. The procedure exploits the continuous records at the stations and just the vertical components and so can be applied to older data for which receiver function techniques cannot be used. © 2015 American Geophysical Union.
