AB	"    The <80 ka basalts-basanites of the Potrillo Volcanic Field (PVF)    form scattered scoria cones, lava flows and maars adjacent to the New    Mexico-Mexico border. MgO ranges up to 12.5%; lavas with MgO<10.7%    have fractionated both olivine and clinopyroxene. Cumulate fragments    are common in the lavas, as are subhedral megacrysts of aluminous    clinopyroxene (with pleonaste inclusions) and kaersutitic amphibole.    REE modelling indicates that these megacrysts could be in equilibrium    with the PVF melts at approximately 1.6-1.7 GPa pressure. The lavas    fall into two geochemical groups: the Main Series (85% of lavas) have  major- and trace-element abundances and ratios closely resembling    those of worldwide ocean-island alkali basalts and basanites (OIB);    the Low-K Series (15%) differ principally by having relatively low K    (sub 2) O and Rb contents. Otherwise, they are chemically    indistinguishable from the Main Series lavas. Sr- and Nd-isotopic    ratios in the two series are identical and vary by scarcely more than    analytical error, averaging (super 87) Sr/ (super 86) Sr = 0.70308 (SD    = 0.00004) and (super 143) Nd/ (super 144) Nd = 0.512952 (SD =    0.000025). Such compositions would be expected if both series    originated from the same mantle source, with Low-K melts generated    when amphibole remained in the residuum. Three PVF lavas have very low    Os contents (<14 ppt) and appear to have become contaminated by    crustal Os. One Main Series picrite has 209 ppt Os and has a gamma    (sub Os) value of +13.6, typical for OIB. This contrasts with    published (super 187) Os/ (super 188) Os ratios for Kilbourne Hole    peridotite mantle xenoliths, which give mostly negative gamma (sub Os)    values and show that Proterozoic lithospheric mantle forms a thick    Mechanical Boundary Layer (MBL) that extends to approximately 70 km    depth beneath the PVF area. The calculated mean primary magma, in    equilibrium with Fo (sub 89) , has Na (sub 2) O and FeO contents that    give a lherzolite decompression melting trajectory from 2.8 GPa (95 km    depth) to 2.2 GPa (70 km depth). Inverse modelling of REE abundances    in Main Series Mg-rich lavas is successful for a model invoking    decompression melting of convecting sub-lithospheric lherzolite mantle    (epsilon Nd = 6.4; T (sub p) approximately 1400 degrees C) between 90    and 70 km. Nevertheless, such a one-stage model cannot account for the    genesis of the Low-K Series because amphibole would not be stable    within convecting mantle at T (sub f) approximately 1400 degrees C.    These magmas can only be accommodated by a three-stage model that    envisages a Thermal Boundary Layer (TBL) freezing conductively onto    the approximately 70 km base of the Proterozoic MBL during the    approximately 20 Myr tectonomagmatic quiescence before PVF eruptions.    As it grew, this was veined by hydrous small-fraction melts from below."
