SHRIMP Pb/U zircon ages of plutonic rocks from Southwest Indian Ridge

Absolute ages of plutonic rocks from mid-ocean ridges provide important constraints on the scale, timing and rates of oceanic crustal accretion, yet few such rocks have been...

洋中脊（mid-ocean ridges）产出的深成岩（plutonic rocks）的绝对年龄，可为洋壳增生（oceanic crustal accretion）的规模、时序与速率提供关键约束；然而目前此类岩石的相关数据仍较为匮乏。
