“…Over the past decade, strontium (Sr) isotope analysis has become an increasingly powerful tool in present-day and past animal ecology, for determining habitat use and mobility/migration (Blum et al, 2001;Britton et al, 2011;Feranec et al, 2007;Hoppe et al, 1999;Hoppe and Koch, 2007;Radloff et al, 2010;Tütken et al, 2011), in tracing food provenance (Almeida and Vasconcelos, 2001;Barbaste et al, 2002;Fortunato et al, 2004;Montgomery et al, 2006;Swoboda et al, 2008;Techer et al, 2011;Voerkelius et al, 2010), in hydrological and forest ecosystem investigations (Böhlke and Horan, 2000;Dijkstra et al, 2003;Drouet et al, 2005bDrouet et al, , 2007Poszwa et al, 2004;Shand et al, 2009), as well as in forensic sciences (Beard and Johnson, 2000;Juarez, 2008).…”

Sr/ 86 Sr reference maps (isoscapes) are a key tool for investigating past human and animal migrations. However, there is little understanding of which biosphere samples are best proxies for local bioavailable Sr when dealing with movements of past populations. In this study, biological and geological samples (ground vegetation, tree leaves, rock leachates, water, soil extracts, as well as modern and archeological animal teeth and snail shells) were collected in the vicinity of two early medieval cemeteries ("Thuringians", 5-6th century AD) in central Germany, in order to characterize 87 Sr/ 86 Sr of the local biosphere. Animal tooth enamel is not appropriate in this specific context to provide a reliable 87 Sr/ 86 Sr baseline for investigating past human migration. Archeological faunal teeth data (pig, sheep/goat, and cattle) indicates a different feeding area compared to that of the human population and modern deer teeth 87 Sr/ 86 Sr such as freshwater bivalve shells and tree cores were examined in order to track potential historic anthropogenic contamination of the water and the vegetation. The data obtained from the archeological bivalve shells show that the modern rivers yield 87 Sr/ 86 Sr ratios which are similar to those of the past. However, the tree cores registered decreasing 87 Sr/ 86 Sr values over time towards present day likely mirroring anthropogenic activities such as forest liming, coal mining and/or soil acidification. The comparison of 87 Sr/ 86 Sr of the Thuringian skeletons excavated in the same area also shows that the vegetation samples are very likely anthropogenically influenced to some extent, affecting especially 87 Sr/ 86 Sr of the shallow rooted plants.

“…Natural strontium (Sr) isotopes have been proved to be useful tools for tracing the past and for monitoring present-day environmental processes (Bain and Bacon, 1994;Åberg, 1995;Shand et al, 2009). The geochemical behaviour of Sr is generally similar to that of Ca (Aubert et al, 2002), but is different from that of the alkali elements K and Na.…”

“…The 87 Sr/ 86 Sr ratio of rainwater, stream water, soils, and rocks were determined by Bain and Bacon (1994) to determine mineral weathering, and the origin of the solutes in the stream water in two Scottish catchments. Additionally, a number of case studies also highlighted that Sr isotopes represented a powerful tool in determining weathering processes and quantifying end-member mixing processes when combined with other hydrochemical data (Shand et al, 2009).…”

“…Previous studies have demonstrated the usefulness of the Sr isotope technique in tracing the geochemical cycling processes of river water (Graustein and Armstrong, 1983;Bain and Bacon, 1994;Capo et al, 1998;Shand et al, 2009). By using 87 Sr/ 86 Sr ratios, Graustein and Armstrong (1983) traced the sources of strontium in natural waters, vegetation, and soil taken from watersheds in the Sangre de Cristo Mountains of New Mexico, and found that more than 75% of the strontium in the vegetation was derived from atmospheric sources, and less than 25% from weathering of the underlying bedrock.…”

“…The Sr isotopic ratios ( 87 Sr/ 86 Sr) of natural materials reflect the sources of Sr available during their formation (Capo et al, 1998). Additionally, 87 Sr/ 86 Sr ratios are ideal source tracers because these isotopes have quite small fractionation during biogeochemical cycling (Pett-Ridge et al, 2009;Shand et al, 2009). One study found that the concentration of Sr varied from 6 to 800 mg L À1 , and averaged~60 mg L À1 in a river water system (Stallard, 1985), whereas another study found that the global river average was 78 mg L À1 (Palmer and Edmond, 1992).…”

a b s t r a c tThe concentrations of dissolved strontium (Sr) and isotope ratios ( 87 Sr/ 86 Sr) in rainwater, river water, and water from forest soil are measured to investigate the contributions of these sources to a river during base flow conditions in the relatively pristine South Qinling Mountains, China. Dissolved Sr concentrations and 87 Sr/ 86 Sr ratios vary significantly between different water types (p < 0.01) suggesting that it is suitable for differentiating sources. Dissolved Sr is also positively correlated with most ions and a range of physicochemical parameters (p < 0.01 and p < 0.05 respectively) in water samples including Ca 2þ , Mg 2þ , EC, and TDS (p < 0.001) indicating their similarities in the drivers of biogeochemical processes and common origins. The correlations between Sr isotopes and Ca/Na, Ca/K, and 1000/Sr ratios suggest that three end-members of atmospheric inputs, carbonate and silicate weathering control the Sr water chemistry in the river water. Using the three-source mixing model, atmospheric inputs, carbonate, and silicate weathering contribute 74%, 20%, and 6% respectively to the dissolved Sr in the river water. This research has provided new insights into the contribution of sources of Sr to a river system in a mountainous catchment.

U–Pb Dating of Cave Spar: A New Shallow Crust Landscape Evolution Tool

et al. 2018

In carbonate terranes, rocks types that provide apatite are not available to effectively use apatite fission track (AFT) or (U/Th)‐He chronometry (AHe). Here we suggest that calcite cave spar can be an effective chronometer and complimentary to AFT and AHe thermochronometers in carbonate regions such as our study area, the Guadalupe Mountains of southeastern New Mexico, and west Texas. Our measured depth of cave spar deposition is 500 ± 250 m beneath the regional water table, formed at temperatures of 40° to 80°C, indicating that these caves and their spar crystals form near the supercritical CO2‐subcritical CO2 boundary where we interpret the origin of both the caves and spar to occur. This depth‐temperature relationship suggests a higher than normal geotherm, likely associated with regional magmatic activity. As a case study we examined the timing of uplift of the Guadalupe Mountains previously attributed to the compressional Laramide orogeny (ca. 90 to 50 Ma), later extensional tectonics associated with Basin and Range (ca. 36 to 28 Ma) or the opening of the Rio Grande Rift (ca. 20 Ma to Present). We show that most of the spar origin is coeval with the ignimbrite flare‐up between 36 and 28 Ma. Our results constrain the initiation of Guadalupe Mountains block uplift, relative to the surrounding terrain, to between 27 and 16 Ma and reconstruct the evolution of a low‐lying regional landscape prior to block uplift from 185 to 28 Ma, in support of models that attribute regional surface uplift to extensional tectonics and associated volcanism.
