“…These 13 C-excess elevations agree well with modern elevations across the Great Basin (~1700 m mean elevation in the north;~900 m mean elevation in the south; Saltus and Thompson, 1995) and published paleotopographic interpretations for the Sierra Nevada (Mulch et al, 2006;Cassel et al, 2009). However, a~1.5 km high 'proto' Southern Alps at~15 Ma is an entirely new interpretation that provides important detail otherwise lacking in the only other paleoelevation study on the mountain range (Chamberlain et al, 1999).…”

a b s t r a c tGrowing pressure on sustainable water resource allocation in the context of global development and rapid environmental change demands rigorous knowledge of how regional water cycles change through time. One of the most attractive and widely utilized approaches for gaining this knowledge is the analysis of lake carbonate stable isotopic compositions. However, endogenic carbonate archives are sensitive to a variety of natural processes and conditions leaving isotopic datasets largely underdetermined. As a consequence, isotopic researchers are often required to assume values for multiple parameters, including temperature of carbonate formation or lake water d 18 O, in order to interpret changes in hydrologic conditions. Here, we review and analyze a global compilation of 57 lacustrine dual carbon and oxygen stable isotope records with a topical focus on the effects of shifting hydrologic balance on endogenic carbonate isotopic compositions.Through integration of multiple large datasets we show that lake carbonate d 18 O values and the lake waters from which they are derived are often shifted by >þ10‰ relative to source waters discharging into the lake. The global pattern of d 18 O and d 13 C covariation observed in >70% of the records studied and in several evaporation experiments demonstrates that isotopic fractionations associated with lake water evaporation cause the heavy carbon and oxygen isotope enrichments observed in most lakes and lake carbonate records. Modeled endogenic calcite compositions in isotopic equilibrium with lake source waters further demonstrate that evaporation effects can be extreme even in lake records where d 18 O and d 13 C covariation is absent. Aridisol pedogenic carbonates show similar isotopic responses to evaporation, and the relevance of evaporative modification to paleoclimatic and paleotopographic research using endogenic carbonate proxies are discussed.Recent advances in stable isotope research techniques present unprecedented opportunities to overcome the underdetermined nature of stable isotopic data through integration of multiple isotopic proxies, including dual element 13 C-excess values and clumped isotope temperature estimates. We demonstrate the utility of applying these multi-proxy approaches to the interpretation of paleohydroclimatic conditions in ancient lake systems. Understanding past, present, and future hydroclimatic systems is a global imperative. Significant progress should be expected as these modern research techniques become more widely applied and integrated with traditional stable isotopic proxies.

“…The loss of clay minerals at depth was probably caused by their conversion into magnetite by complex reactions driven by frictional heating and hot fluids injected by the thermal pressurization slip mechanism (Lin 2011). For example, oxidized alteration of chlorite forms some iron oxides (Chamberlain et al 1999), and siderite changes into pyrite and magnetite under low-oxygen conditions (Tanikawa et al 2008).

We measured the magnetic susceptibility of the core from the first borehole of the Wenchuan Earthquake (May 12, 2008, Mw7.9) Fault Scientific Drilling Project (WFSD-1) at 1-cm intervals. The correlations between magnetic susceptibility anomalies and fault rock occurrence are shown by a few fault zones in the WFSD-1 core. The values for the mass and ferromagnetic material magnetic susceptibility for the sample at 589.25-m depth are higher than those for the other samples. All the thermomagnetic curves display a rapid increase in slope after 380°C, and a marked peak occurs at about 510°C in the heating curves. The cooling curves are clearly higher than the heating curves. The saturation magnetization (Ms) shows a significant peak at a depth of 589.25 m, as do the mass magnetic susceptibility and the ferrimagnetic magnetic susceptibility. The mechanism principally responsible for the high magnetic susceptibility at a depth of 589.25 m might be the production of new magnetite from iron-bearing silicates (e.g., chlorite) or clays caused by frictional heating during seismic slip. Therefore, we suggest that the presence of high magnetic susceptibility fault gouges in the same country rock can be considered as an indicator of earthquakes or seismic signatures.

“…Patterns in the distribution of stable oxygen and hydrogen isotopes in precipitation and surface waters have long been used as a tool for the study of hydrological and surface processes, but studies of geological proxies have generally focused on isotopic variation caused by changes in atmospheric circulation and/or surface elevation (e.g., Chamberlain et al, 1999;Chamberlain and Poage, 2000;Garzione et al, 2000;Garzione et al, 2006;Rowley and Currie, 2006). In this study, we reconstruct trends in the oxygen isotopic composition of lake and river water (δ 18 O lw and δ…”

Isotopic and elemental records of authigenic calcite from lacustrine deposits in the intraforeland basins of Utah were analyzed in an effort to reconstruct the regional paleoclimate, paleohydrology, and paleotopography of the early Cenozoic central North American Cordillera. Isotopic profi les for Paleogene Lakes Uinta, Flagstaff, and Claron show relatively large oxygen isotopic shifts that are diachronous among basins with an ~7‰ decrease in δ 18O calcite values at ca. 45 Ma in Lake Flagstaff, an ~5‰ decrease in δ 18O calcite values between ca. 42 and 35 Ma in Lake Claron, and an ~6‰ decrease in δ 18O calcite values between ca. 44 and 43 Ma in Lake Uinta. We interpret these negative oxygen isotopic shifts to be the combined result of increased hypsometric mean elevation of basin catchments and related freshening associated with basin infi lling. The basins studied also have undergone periods of intense evaporation during periods of hydrologic closure, which, for example, produced an ~7‰ increase in δ 18O calcite values in Lake Uinta beginning at ca. 51 Ma. Hydrologic closure in the Uinta Basin probably resulted from growth of local topography that diverted previously substantial infl ows from low elevation regions within the foreland.This study adds to the growing body of evidence that suggests a pattern of alongstrike variations in the timing of topographic development and dissection of the Cordilleran landscape during the early Cenozoic. We favor an interpretation that calls for the middle Eocene rearrangement of regional drainage patterns such that intraforeland basins that once received waters from far-fl ung foreland river systems became dominated by infl ows of low δ 18O waters from catchments with higher hypsometric mean elevations that drained the adjacent hinterland and/or basin-bounding uplifts. This drainage reorganization is analogous but subsequent to the large-scale integration of catchments in the northern Cordillera that has been recognized on the basis of isotopic and sedimentological evidence in Montana and Idaho at ca. 50-47 Ma, with rivers fl owing southeast into Lake Gosiute at ca. 49 Ma and then for a time reaching Lake Uinta, causing a prominent highstand in that lake at 48.6 Ma. The negative oxygen isotopic shifts presented herein, which occurred between ca. 45 and ca. 35 Ma in the intraforeland basins of Utah, may refl ect the north-to-south progression of drainage integration in the Cordillera as magmatism and related topography swept southward through the hinterland and increased the hypsometric mean of catchments that fed subjacent intraforeland basins.
