Lithosphere-Asthenosphere boundary found to become deeper under older crust, thus supporting the suggestion that the discontinuity is closely interrelated to the LAB. Beneath oceanic crust, the LAB ranges anywhere from 50 to 140 km in depth except at mid-ocean ridges where the LAB is no deeper than the depth of the new crust being created. Seismic evidence shows that oceanic plates do thicken with age. This would suggest that the Lithosphere-Asthenosphere boundary underneath oceanic lithosphere also deepens with plate age. Data from ocean seismometers indicate a sharp age-dependent LAB beneath the Pacific and Philippine plates and has been interpreted as evidence for
Fools Gold/What the World Is Waiting For and "What the World Is Waiting For" were recorded at Sawmills Studios in Cornwall during the late summer of 1989, with additional vocal and guitar parts recorded later at London's Battery Studios, during the autumn of 1989. The tracks had been worked on for four months, and the intention was to put "What the World Is Waiting For" as the A side; however, when Roddy Mckenna, Silvertone's A&R man, heard "Fools Gold" he urged the band to use that as the A-side. The band were not completely convinced, and it was agreed, instead, to release the two tracks as a
