Data Services Products: EMC-Crustal_Thickness_Error Crustal thickness values within the western United States derived from receiver function observations

Summary

The model crustal thicknesses values are based on common conversion point (CCP) stacking of receiver functions calculated from data recorded by USArray stations and other permanent and temporary deployments in the western United States.

Data Set Description [Gilbert, 2012], Crustal thicknesses are based on a dataset comprised of close to 50,000 P-to-S receiver functions recorded by stations in the western United States. Stacking the receiver functions into common conversion point (CCP) stacking bins facilities identifying lateral variations in crustal thickness. Thickness values range from less than 30 km thick to more than 50 km thick across the region. Errors associated with crustal thickness values vary between 0 and 4.5 km and are estimated from bootstrap resampling.
 
Supplemental Information
 

Map of crustal thickness variations
[Gilbert, 2012] Map of crustal thickness. Blue marks areas of thicker crust and red regions correspond to areas of thinner crust. Maximum thicknesses reach >50 km along the border between Colorado and Wyoming. Crust <30 km thick is located within the southern Basin and Range in southern Arizona. The intensity of colors corresponds to the confidence of the receiver function pick in that area.
