Between a Hotspot and a Cold Spot: Isotopic Variation in the Southeast Indian Ridge Asthenosphere, 86{degrees}E-118{degrees}E
Glasses from a 2600 km section of the Southeast Indian Ridge west of the Australian–Antarctic Discordance all possess Nd–Pb–Sr isotopic signatures typical of Indian Ocean ridge basalt. The boundary between Pacific- and Indian-Ocean-type ridge basalt within the Discordance thus marks the westernmost...
