- Abstract:
- Large igneous provinces (LIPs) have considerable geodynamic and palaeoclimatic significance since they may represent outpourings of basaltic magma on a scale much larger than anything occurring today. The largest oceanic LIP, the Ontong Java Plateau, has an area about six times that of the UK and crust up to 40 km thick. Samples to be recovered by ODP Leg 192 will be used to address the fundamental question of the origin of oceanic LIPs. Do they represent the initiation of deep mantle plumes (the plume-head model), or are they simply the result of plume-ridge interaction over long periods (the Iceland model)? We propose to apply high-precision Ar-Ar dating to assess the age and duration of magmatism in order to test these alternative models.
