Spatio-temporal interactions among tectonics, climate, erosion and sedimentation in the southern Central Andes, NW Argentina

Mountain building is one of the most significant processes in shaping Earth’s surface over geological time; at active convergent margins protracted tectonic shortening and surface uplift impact atmospheric flow patterns, and can thus cause an asymmetry in the distribution and amount of rainfall at hemispheric scale. In turn, this produces steep gradients in vegetation cover and the efficiency of erosional and depositional processes across an orogen. In mountain ranges, such as the South American Andes and the Himalaya, precipitation is focused along the windward flanks of high topography, while the orogenic interior is characterized by progressively lower rainfall amounts. In such settings, tectonics, climate, and surface processes are not only tightly linked, but there may be intriguing feedbacks among them, with the potential to impact crustal-scale processes. Importantly, tectono-climatic interactions and the resulting surface processes impact a wide range of geological and biological processes that may control the type and amount of sediment that is provided to adjacent forelands and the development of species migration corridors/barriers.

Qda de Humahuaca

The Andes constitute an important orographic barrier in the southern hemisphere, impacting atmospheric circulation, the amount and distribution of rainfall, and Earth-surface processes in a highly asymmetric manner (Fig. 1). In the Central Andes of NW Argentina, the Andean Plateau (Puna) and the intermontane basins of the adjacent Eastern Cordillera constitute geological archives that furnish spatiotemporal information on surface uplift and associated paleo-environmental change. Today, rainfall in NW Argentina is focused along the windward flanks of the Eastern Cordillera, while its intermontane basins and the Puna constitute high-elevation regions with strongly reduced rainfall. The present-day influence of these topographic characteristics on precipitation patterns is reflected by systematic changes in the hydrogen stable isotope ratios of meteoric water. Proxy archives from basin strata record past environmental conditions and provide insight into the nature of topographic growth through time.

Hydrogen-isotope geochemistry of hydrated volcanic glass

One particular method to investigate the relationship between tectono-sedimentary events and paleoenvironmental change is to analyze hydrated volcanic glass shards for their hydrogen stable-isotope composition as a proxy for surface uplift and associated climatic shifts. This approach is possible, because rhyolitic glass incorporates up to ca. 10 wt% of meteoric water after deposition and becomes saturated over ~1-10 kyr, after which further hydrogen exchange is negligible. Since the glass-hydration process occurs with a systematic isotopic fractionation, the D/H-ratio of the glass (δDg) represents a unique and time-integrated fingerprint of the hydrogen-isotope composition of meteoric water (δDw) present at that time. Finally, δDg-values appear to be resistant to diagenetic alteration and can be preserved over geological time scales, which makes volcanic glass a suitable material for the reconstruction of paleoenvironmental conditions and the examination of feedbacks between tectonic processes and climate. Hydrated glass therefore provides a very useful set of isotope data that can be related to climate change and/or paleoaltimetry.

Paleoerosion rate reconstruction by terrestrial cosmogenic radionuclide geochemistry

As cosmic radiation enters the Earth’s atmosphere it triggers a cascading chain reaction that causes high-energy subatomic particles to bombard the surface including rocks exposed. This particle flux interacts with Si and O in surface-near quartz-bearing rocks, by which 26Al, 10Be, 21Ne and 3He - to name the most important - is formed at certain production rates (PSource) over time. The longer a rock surface is exposed to this radiation (i.e., the slower the denudation rate) the more in-situ 10Be is produced. Denudation rates from concentrations of in situ-produced cosmogenic 10Be (εr, cm/yr) in detrital quartz are derived from the relationship between the 10Be surface-production rate (PSource, atoms/g/yr) and the attained nuclide concentrations in quartz-bearing rocks upon steady hillslope denudation (CH, atoms/g). River sands theoretically average denudation rates from their contributing catchments. From here it is a small, but non-trivial step to derive paleo-denudation rates from ancient river sands in sedimentary deposits.

Intermontane basins along the eastern Puna Plateau margin in NW Argentina, such as the Humahuaca Basin, are our natural laboratories to study the effects of uplift and climate change. As a consequence of the Andean eastward migration, such areas were incorporated into the orogen during the late Miocene to Pliocene, experienced uplift, and ultimately orographic barrier uplift associated with dryness in the newly formed intermontane hinterland basins.

Note the correlation between orographically-induced aridification basin, the positive shift in δDg values from volcanic glass, and a drop in the denudation rates to near-modern values.

To investigate long-term surface processes along a tectonically active mountain belt, we have evaluated 10Be-derived paleo-denudation rates from the Mio-Pliocene (ca. 6–2 Ma) strata of the intermontane Humahuaca Basin (Eastern Cordillera, northwest Argentina) – a region that experienced tectonic growth of its bounding ranges, basin isolation, and orographic aridification. Our results show a tenfold decrease in denudation rates coinciding with the establishment of an orographic barrier to rainfall after 3 Ma, suggesting a close link between rainfall and hillslope denudation, while background tectonics appear to play a minor role in modifying denudation.
