Different parts of the basin crust have different isotopic signatures. This means the crust is heterogeneous with differing magma sources. The older crust formed by extension and rifting has Pacific MORB affinities while the newer seafloor spreading crust has Indian MORB characteristics and an arc-like source is also involved. Isotope studies indicate that initial Pacific MORB mantle has mixed with and been subsequently replaced by Indian MORB mantle. According to Hergt & Hawkesworth (1994) the data indicate that these variations are due to compositional changes in the asthenosphere and not the downgoing slab. This was accomplished by slab rollback and the southward migration of the propagating ridges. The source of the arc component may be contamination by arc lithosphere, infiltration of magma source by slab-derived flux and mixing between upwelling mantle and arc magmas during early extension. The data from the Lau basin suggests the isotopic heterogeneity is caused by selective melting of separate domains as opposed to mixing injections of different melt batches (Hergt & Hawkesworth 1994, Hawkins 1995, Taylor et al 1996).
i see... gotta read between the lines on that one...

just got home froma bit of a bender and im sittimg here at 4.36 drinking a beer before i go to bed.
Just thought i would share that with all of you.
Cheers
whatcha think of this model, tried to make a monkey
Though it's still unfinished
still recovering from working all weekend and watching the F1 last night till 6am
anyone watch? what a farce.... 6cars started 14 retired on the warm up lap, what a sight and a sad day for the F1

LOL yeh had the clip of that before, hahah, she is all happy and runs to wards it, then BAM! hahha, she slides off, like a rag doll 
btw, how do you make movie clips into gif files?

damn i'm moving Wednesday, the days of living solo are over, gotta go back to my parents house after 2 years.

Actually i love it because there is freedom, but on the other hand it gets hard if you know what i mean, i mean there is a SHITLOAD of bills.. maybe a down the track a little bit when i can handle it i'll come back solo again.
BUT for other reasons its because of my parents house, they are paying the house off over there when i'm paying rent here. If i payed the rent for this place to them for the house over there even counting all the bills then it will be good for them..
oh well..
oh du ist a gut boi mehran
