Abstract
Teleseismic body waves from seismic broadband and short periodstations
were used to investigate the crustal structure of Norwaythrough inversion
of the receiver functions. The Moho depths ofthe Baltic Shield are
quite well known from previous studiesincluding seismic experiments
and spectral ratio technique.However, the results on the details
of the crustal structure areinconsistent. This study provided more
detailed crustalstructure information at 16 locations than previously
known andgenerally confirmed Moho depth results obtained in earlier
studies. Significant differences are seen at a few sites. The Moho
for the various sites was found at depths between 28 and 44 km. In
summary, the crustal thicknessincreases from the West Coast of Norway,
away from thecontinental margin, towards the centre of the Baltic
Shield andfrom Southwest to the Northeast. This corresponds to theincreasing
age of the crust. The P velocities in the crust atmost sites show
a gradual increase from about 6.0 to 7.1 km/s, withoutclear layering.
