“…In fact, it has been shown that degassing of the Colombian segment alone contributes to 50% of the total Andean CO 2 emissions (Aiuppa et al., 2017; Lages et al., 2019). The geochemical evidence presented here, together with the extremely high CO 2 fluxes and the recently reported MORB‐like He isotopic signatures of olivine inclusions from the NVP (Lages et al., 2021), not only support the notion of a mantle origin for these typical orogenic andesites, but also make the Northern Andean chain a natural laboratory to test the interconnections among oceans, atmosphere, life, and the solid Earth.…”

The biological and sedimentological surface-processes recorded in the compositions of seafloor sediments are transferred to the Earth's interior at convergent margins. These materials can be either recycled into the deep mantle forming long-term compositional heterogeneities (Stracke et al., 2005), or be reworked shallowly into arc magmas giving shape to the continental masses (Behn et al., 2011). While it has been long recognized that subducted sediments exert an important control in the compositions of island arcs (Plank, 2005), less is known about the geochemical imprint of the oceanic realm in thick-crusted continental arc sections. This is because subducting sediments (i.e., GLOSS; Plank, 2013) are compositionally very similar to the overriding continental crust with which ascending magmas may interact, and because forearc subduction erosion may introduce a volumetrically higher crustal influx at most continental margins that could overwhelm the oceanic inputs (Straub et al., 2020).

“…We focus on pyroxene in Peruvian volcanic products as, due to the more evolved nature of magmas produced along the CVZ, olivine is scarce and recurrently found in insufficient amounts for noble gas analyses. We followed identical sample preparation and analytical procedures to those described in Lages et al (2021) for bulk element and isotope composition measurements of noble gases in each sample.…”

“…where [U] and [Th] correspond to the abundance of these elements in terrigenous products subducted in the region (Plank, 2014;Table S-3). Additionally, we assume (i) mantle 4 He concentrations in the same range of those measured in gas-rich fluid inclusions from Andean products (e.g., Ecuador; ×10 -12 mol/g; Lages et al, 2021), and (ii) a mantle end member derived from the highest 3 He/ 4 He ratios measured in FIs (8.5 R A , Nevado del Ruiz; Lages et al, 2021). From these, we estimate that in 10 kyr enough radiogenic 4 He would be produced to lower the helium isotope signature of the underlying mantle wedge toward North/South Chile end member values.…”

“…According to petrological evidence (Straub et al, 2011), the SCN lavas derive from a sub-arc mantle affected by the infiltration of silicic crustal material from the subducted slab to the point that -secondary pyroxenite veins formed. If SCN magmas were completely related to subduction, then the fluid (Petterson, 1992;Hilton et al, 2002;Italiano et al, 2017;Lages et al, 2021a;Lages et al, 2021b).

The heterogeneity of the Mexican lithospheric mantle: Clues from noble gas and CO2 isotopes in fluid inclusions

et al. 2022

The abundance of mantle-derived rocks and lavas, in combination with its tectonic evolution, render Mexico a perfect laboratory to investigate the chemical and the isotopic heterogeneity of the lithospheric mantle. New data on the composition of noble gases and CO2 in Mexican mantle xenoliths and lavas is reported. Our samples consist of six ultramafic nodules from the Durango Volcanic Field (DVF) and the San Quintin Volcanic Field (SQVF), monogenetic complexes belonging to the Mexican Basin and Range province; and four lavas from the Sierra Chichinautzin (SCN), a Quaternary monogenetic volcanic field located in the Mexican volcanic arc. Ne and Ar isotopes in fluid inclusions reveal mixing between atmospheric and MORB-like fluids (e.g., 40Ar/36Ar < 1,200). DVF and SQVF nodules record low 40Ar/36Ar and 4He/20Ne that confirm the existence of recycled atmospheric-derived noble gases in the local mantle. The averages of the Rc/Ra ratios (3He/4He corrected for atmospheric contamination) measured in Mexican localities are within the MORB-like range: DVF= 8.39 ± 0.24 Ra, SQVF = 7.43 ± 0.19 Ra and SCN lavas = 7.15 ± 0.33 Ra (1σ). With the aim of assessing the isotopic variability of the Mexican lithospheric mantle, the above results were compared with similar data previously obtained from ultramafic nodules found in the Ventura Espiritu Santo Volcanic Field (VESVF), another Quaternary monogenetic volcanic complex belonging the Basin and Range. The higher 3He/4He ratios in DVF relative to those reported for the VESVF and the SQVF are explained as reflecting different ages of mantle refertilization, triggered by the retreating of the Farallon slab (∼40 Ma ago) and associated delamination slab processes. We propose that the DVF mantle was refertilized more recently (<10 Ma ago) than the mantle beneath the SQVF and VESVF (∼40–20 Ma ago). On the other hand, He-Ne-Ar compositions of SCN olivines share similarities with VESVF xenoliths, suggesting a relatively homogeneous lithospheric mantle in central Mexico. Finally, DVF and the SCN samples exhibit δ13C values within the MORB range (comparable to other values previously reported in fluid inclusions and fumaroles from Popocatépetl, Colima—Ceboruco volcanoes). While we explain the MORB-like carbon signatures of the DVF samples as the result of the above-mentioned refertilization process, the SCN signatures likely reflect either (i) trapping of isotopically fractionated CO2 derived from magmatic degassing or (ii) a mantle source unaffected by subduction-related crustal carbon recycling.
