The application of a gravimetric forward modelling of the lithospheric structure for an estimate of the average density of the upper asthenosphere
《Geodesy and Geodynamics》2019年第4期265-275,共11页Wenjin Chen Robert Tenzer 
the HK science project 1ZE8F: Remote-sensing data for studding the Earth’s and planetary inner structure
The average density of 3300 kg m-3 is often attributed for the asthenosphere. In this study, we inspect this value by estimating the average value of the(upper) asthenosphere based on applying the gravimetric forward ...
