| dc.description | There are strong regional trends in the <sup>87</sup>Sr/<sup>86</sup>Sr ratios and δ<sup>18</sup>O values of Miocene volcanic rocks from the Mojave Desert of southern California. Because these rocks contain a large component of recycled crust, their isotopic patterns can be used to study pre‐Miocene crustal structure which has been otherwise obscured and distorted by Mesozoic magmatism. Initial whole rock <sup>87</sup>Sr/<sup>86</sup>Sr ratios (r<sub>i</sub>) increase and δ<sup>18</sup>O values of silicic magmas decrease with distance inland; r<sub>i</sub> also increases with SiO<sub>2</sub>, indicating contamination by radiogenic crustal rocks. Initial <sup>87</sup>Sr/<sup>86</sup>Sr ratios in the most primitive basalts are high (0.7045–0.7095), indicating derivation from an enriched mantle source. Correlations of r<sub>i</sub> and δ<sup>18</sup>O with longitude indicate an eastward change in the nature of the contaminant. Silicic rocks have r<sub>i</sub> and δ<sup>18</sup>O of 0.705–0.707 and 9–11‰, respectively, in the western and central Mojave Desert, and 0.708–0.710 and 7–8‰ near the Colorado River. High δ<sup>18</sup>O values of phenocrysts in rhyolites from the western Mojave Desert indicate that these rocks were derived from a high δ<sup>18</sup>O (>10‰) source. The most likely candidate for this material is underthrust metamorphic rocks of the Mesozoic‐Tertiary subduction complex (e.g., Rand‐Pelona‐Orocopia schist and related lithologies). This implies that some of the North American lithospheric mande was stripped from the western Mojave Desert during Mesozoic‐Paleogene subduction. The smoothness of the eastward increase in r<sub>i</sub> constrains models for the tectonic evolution of southern California because no discontinuities corresponding to any of several proposed zones of pre‐Tertiary rifting or faulting are present. |
