Crustal structure of the Reykjanes Ridge near 62°N, on the basis of seismic refraction and gravity data

Moho and basement depth in the NE Atlantic Ocean based on seismic refraction data and receiver functions

“…Over time, the thickness of the oceanic crust decreased to values of around 8 km at a distance of 250 km from the continent-ocean boundary. Refraction seismic experiments on the Reykjanes Ridge away from Iceland indicate variations in the crustal thickness that ranged from 4 to 9 km (Bunch & Kennett 1980;Smallwood et al 1995;Navin et al 1998;Jacoby et al 2007).…”

Hotspot Iceland: An introduction

“…The ridge morphology near Iceland is marked by volcanism and fracturing, as presented by Höskuldsson et al (2007). Its crustal structure appears affected by plume outflow, similar to the Icelandic crust, and the thin crust-thick crust controversy extends from Iceland into the Atlantic as discussed by Jacoby et al (2007).…”

An alternative method for density variation modeling of the crust based on 3-D gravity inversion

“…to find the density of the source masses from the given gravity field functionals, such as norm of the gravity vector (from gravimetry), gravity vector (from the inertial systems or astronomical observations plus gravimetry), gravity potential (from geodetic leveling), on or above the surface of the earth, is of particular interest for geoscience studies. For this reason extensive contributions are made in this respect that as recent examples we refer to Welford et al (2010), Aitken (2010), Schreiber et al (2010), Kimbell et al (2010), Welford and Hall (2007), Jacoby et al (2007), Camacho et al (2007), Ebbing et al (2007), Bosch et al (2006), Strykowski et al (2005), Tiberi et al (2005), Pinto et al (2005), Jacoby and Çavşak (2005), Cai and Wang (2005), Kaban et al (2004), Wang et al (2004), Widiwijayanti et al (2004), Çavşak et al (2002), Koslovskaya et al (2004), Rivero et al (2002), , Silva et al (2001Silva et al ( , 2002Silva et al ( , 2007, Tondi et al (2000).…”
