主　　题：Acceleration records receiver functions Northeast Mexico Mohorovicic discontinuity 

摘      要：We obtained 805 receiver functions from velocity data of four permanent and six temporary seismic stations and 38 from acceleration data of three permanent stations located in northeastern Mexico to get the spatial distribution of the Mohorovicic (Moho) discontinuity in that region. To prove the feasibility of using acceleration records to obtain receiver functions, we obtain receiver functions from velocity and acceleration records from instruments located less than 1 m from each other at the permanent stations. We conclude that it is possible to use the acceleration data by filtering and integrating it. We estimated the depth of the Moho discontinuity under each station. We observed that the thickness of the crust is thicker under the Basin and Range and Sierra Madre Oriental provinces to the west, reaching values greater than 33 km and being, on average, 32 +/- 2 km. Then, the crust gets thinner in the Sabinas and Magiscatzin basins to the east, with an average thickness of 29 +/- 2 km.
