As many OIB sources might be mixtures of depleted mantle and enriched mantles (different types), there should be no fixed trace element composition for OIB modelling. You can try using different mixing ratios of possible end-members.

There is a good review of this issue:

Hofmann, A.W., 2003. Sampling mantle heterogeneity through oceanic basalts: isotopes and trace elements. In: R.W. Carlson (Editor), The mantle and Core. Treatise on geochemistry. Elsevier, Amsterdam, pp. 61-101.

There could be various approaches to determine such, either from direct analysis of mantle xenoliths or via inverse modelling from a dataset on primitive mantle-derived melts. As a result you will see that the composition of upper mantle can vary significantly. If you consider that mantle is not a homogeneous source, but rather a mixture of different lithologies the answer will be still more complicated. In addition to the reference given to you by Chao Zhang above I can suggest another reference such as Pilet S., Baker M.B., Stolper E.M. Metasomatized lithosphere and the origin of alkaline lavas // Science, 2008, v. 320, p. 916-919.

If you read Russian, you can go and see my habilitation thesis which includes some discussion on such a topic.

In Chapter 1 https://dl.dropbox.com/u/74801948/018-079-Chapter-1.pdf you will find Table 1.1 with major element compositions of variable sources such as depleted MORB mantle (DMM), fertile peridotite PHN1611, pyrolite (R1975, MS1995), piclogite (66SAL-1, MIX1G) and eclogite (Gb108, G2, Нкк). Trace element compositions are available for some of these compositions in Workman, Hart, 2005 (DMM), McDonough, Sun, 1995 (MS1995), Yaxley,

Sobolev, 2007 (Gb108), Rudnick, Fountain, 1995 (Нкк which is Russian for LCC). In Chapter 3 I performed some simple modelling where I used as a source of mantle either DMM or an arbitrary mix between DMM and various types of eclogite-piclogite with trace element composition of MORB or real compositions from literature. An example of such simple modelling you can find elsewhere in literature. I give reference to my paper (Ivanov A.V. Evaluation of different models for the origin of the Siberian traps. / Foulger G.R., Jurdy D.M., eds. The origin of melting anomalies: Plates, plumes and planetary processes // Geological Society of America Special Paper, 2007, v. 430, p. 669—691. Fig. 10, for La and Yb http://www.academia.edu/492738/Evaluation_of_different_models_for_the_origin_of_the_Siberian_Traps) simply because it is the easiest way to me to pick up a reference. But you can find much more in the literature.

Hope it helps.

Thank you very much...is much more that I spect....thanks

Hi Pablo
