“…3) Pb/ 204 Pb = 37.235-39.427). As noted earlier, many Cenozoic felsic igneous rocks and ores in central New Mexico and Colorado have Pb isotopic compositions that reflect the derivation of Pb from from both lower and upper crustal sources (Lipman et al, 1978;Doe et al, 1979;Stacey and Hedlund, 1983;Varga and Smith, 1984;Riciputi et al, 1995;Thibodeau et al, 2013). Most of New Mexico and southern Colorado is underlain by the Mazatzal Province , as doi:10.1130/B31135.1 Geological Society of America Bulletin, published online on 3 June 2015 which, in southeastern Arizona, is also the southeastern Arizona province.…”

“…Sulfide minerals and felsic igneous rocks associated with Laramide porphyry copper deposits in Arizona have Pb isotopic ratios that reflect these variations and are thus inferred to have inherited Pb from basement rocks or their sources (Bouse et al, 1999). To the east, the isotopic compositions of Pb in the Cenozoic ore deposits and felsic igneous rocks of New Mexico and southern Colorado also broadly reflects the inheritance of Pb from Proterozoic basement rocks or from crustal sources that evolved from them (Lipman et al, 1978;Doe et al, 1979;Stacey and Hedlund, 1983;Varga and Smith, 1984;Riciputi et al, 1995;Thibodeau et al, 2013). Because turquoise forms in the weathered portions of many copper porphyry deposits, Proterozoic crustal provinces of the Southwest, as defined by Pb isotopes, provide an important basis upon which to interpret the source of turquoise.…”

The archaeological record shows that turquoise was widely mined and highly valued by pre-Hispanic societies in the southwestern United States, and it has long been assumed that much of the turquoise noted in ancient Mesoamerica was traded from this region. However, little is understood about the acquisition and exchange of turquoise by Native American societies because the geological sources of most turquoise artifacts from archaeological sites in the southwestern U.S. and Mexico are not known. We evaluate the potential for Pb and Sr isotopic ratios to indicate the geological provenance of turquoise artifacts recovered from these regions. Pb and Sr isotopic measurements were made on 137 geological samples of turquoise from 19 mining districts across the southwestern United States and northern Mexico. These data reveal that isotopic signatures of turquoise deposits vary geographically according to regional and local differences in the geologic settings of turquoise mineralization. As an archaeological case study, we also report Pb and Sr isotopic data on 10 turquoise artifacts recovered from three late pre-Hispanic (ca. A.D. 1250-1400) ancestral Zuni sites located in the El Morro Valley of western New Mexico. These have isotopic signatures uniquely consistent with the turquoise deposits of the Cerrillos Hills, a location identified in Zuni traditional history as an ancient source of turquoise. These data thus establish Pb and Sr isotopic measurements as powerful tools for determining the sources of turquoise artifacts and provide a new framework for evaluating the role of turquoise in pre-Hispanic exchange networks across North America.

“…Pb and Sr purification was done in columns with Sr-Spec resin (Eichrom Industries, Darien, Illinois, USA) using twice-distilled HCl and HNO 3 with different molarity. Lead isotope analyses were done according to procedures described by Thibodeau et al (2013), on a GV Instruments multicollector-inductively coupled plasma-mass spectrometer (MC-ICP-MS). All samples were diluted below 50 ppb, and a Tl spike was added to each sample.…”

Geochemical and isotopic study of Mesozoic magmatism in the Sonobari Complex, western Mexico: Implications for the tectonic evolution of southwestern North America

et al. 2017

The Sonobari Complex in northwestern Mexico preserves evidence of the consolidation of Pangaea and the Cordilleran orogenic cycle. Six Meso zoic magmatic pulses extending from the Early Triassic to the Paleocene are recognized in this complex. The volumetrically predominant rocks are calcalkaline metaluminous and peraluminous granitoids. Mafic rocks are mainly tholeiitic gabbros. All studied rocks show high concentrations of large ion lithophile elements (LILE) and negative Nb, Ta, and Ti anomalies. Initial Nd and Sr isotopic ratios in granitoids (εNd (i) = -5.7 to -0.5; 87 Sr/ 86 Sr (i) = 0.70630-0.71302) point to evolved continental sources, while radiogenic Pb isotopes ( 206 Pb/ 204 Pb (i) = 16.292-19.17; 207 Pb/ 204 Pb (i) = 15.503-15.666; 208 Pb/ 204 Pb (i) = 35.257-38.984) indicate a heterogeneous basement. Initial Nd and Sr isotope ratios in mafic rocks (εNd (i) = -1.9 to +5.0; 87 Sr/ 86 Sr (i) = 0.70384-0.70626) point to mantle sources with crustal assimilation, which is also supported by the radiogenic Pb values ( 206 Pb/ 204 Pb (i) = 18.412-19.081; 207 Pb/ 204 Pb (i) = 15.595-15.672; 208 Pb/ 204 Pb (i) = 38.147-38.988).Geochemical and isotopic signatures suggest that magmatic rocks in the complex orig inated from fractional crystallization with assimilation of a heterogeneous basement isotopically similar to the Grenville orogen of Mexico. Whole rock compositions are compatible with volcanicarc followed by backarc tectonic settings, where subduction and extensional processes occurred. Therefore, the main granitic pulses in the Sonobari Complex originated af ter the late Paleozoic GondwanaLaurentia collision, by subduction of oce anic plates or microplates along the western border of Pangea. Also, two extensionrelated magmatic pulses occurred after the Late Jurassic and in the Cenomanian, separated by a collisional orogenic event that is recorded by regional metamorphism. The continental arc setting of the Sonobari Complex differs from the oceanic arc context of the GuerreroAlisitos super terrane, indicating that there is no genetic relation between these blocks as previously proposed; rather, a relationship with the eastern Peninsular Ranges batholith is proposed.
