Temperature is one of the key parameters controlling lithospheric and mantl
e dynamics and rheology. Using recent experimental data on elastic paramete
rs and anelasticity, we obtain models of temperature at 50 to 200 km depth
beneath Europe from the global P wave velocity model of Bijwaard et al. [19
98] and the regional S wave velocity model of Marquering and Snieder [1996]
, Forward modeling of seismic velocity allows us to assess the sensitivity
of velocity to various parameters. In the depth range of interest, variatio
ns in temperature (when below the solidus) yield the largest effects. For a
100 degrees C increase in temperature, a decrease of 0.52% in V-P and 0.7-
4.5% in V-S is predicted, where the strongest decrease is due to the large
effect of anelasticity at high temperature, The effect of composition is ex
pected to give velocity anomalies <1% for the shallow mantle and would ther
efore be difficult to resolve. At depths >80 km the relative amplitudes of
the European V-P and V-S anomalies are consistent with a thermal origin. At
shallower depths, variations in crustal thickness and possibly the presenc
e of partial melt appear to have an additional effect, mainly on S wave vel
ocity. In regions where both P and S anomalies are well-resolved, V-P- and
V-S-derived thermal models agree well with each other and with temperatures
determined from surface heat flow observations. Furthermore, the thermal m
odels are consistent with known tectonics. The inferred temperatures Vary s
ignificantly, from around 400 degrees C below an average mantle adiabat at
100 km depth under the Russian Platform and a 300 degrees C increase from e
ast to west across the Tornquist-Teisseyre zone to temperatures around the
mantle adiabat in the depth range 50-200 km under areas with present surfac
e volcanism. In spite of the uncertainties in the calculation of temperatur
es due to uncertainties in the experimental elastic parameters and anelasti
city and uncertainties associated with tomographic imaging, we find that th
e tomographic models of the shallow mantle under Europe can yield useful es
timates of the thermal structure.
