The Dutch uppermost crust is very well-mapped (to ~3km) using extensive active seismic, short period passive seismic, and well logs. However, very limited information about the deep structure is available. Our understanding of the Moho depths beneath the Netherlands and its implications on geodynamics still carry inconsistencies, due to conflicting models from previous active deep reflection and passive seismic data. In northern Netherlands and the Roer Valley Graben, the existing models show conflicting thickening and thinning of the Moho and geodynamics of subsidence and uplift history. In central Netherlands, where ultra-deep geothermal resources are being explored, it is unclear if the Moho is deepened or uplifted, which has implications on how close the mantle materials are to the upper crust and its effect on geothermal gradient and resources. Moreover, the deep reflection seismic gives Moho depths only along 3 onshore profiles and the model derived from passive seismic did not include receiver function analysis, which is known to be sensitive to subsurface discontinuities.

In this study, we present results from 1D layered models established underneath the available broadband seismic stations in the Netherlands using receiver functions. Teleseismic earthquake records are used to calculate P- to S-wave conversions from discontinuities beneath the stations. The layered crustal model would provide valuable information to resolve inconsistencies in previous models and would be crucial for decision-makers for the future ambition of utilising the Dutch subsurface for ultra-deep activities.
