The icy satellites of the outer Solar System show surfaces strongly deformed by tectonic activity, which mostly shows wide strike-slip zones. structural pattern recognized on such regions can be ascribed to deformation observed terrestrial analogs identified in glaciers, whose flow produces structures that bear key information compare and better understand surface subsurface development satellites. Multiscale analysis is used acquire local- regional-scale datasets are compared with satellite...
ABSTRACT This study presents the first detailed glacial geomorphological map of sediment-landform assemblages formed by three eastern outlet glaciers former Patagonian Ice Sheet. These occupied Río Corcovado, Huemul and Lago Palena/General Vintter valleys, Chubut province, Argentina (43°S, 71°W). By combining remote sensing field-mapping, we build on previous ice-sheet scale mapping geological surveys to provide high-resolution spatial information local ice-contact glaciogenic,...
Abstract The Last Glacial Termination (T1) featured major changes in global circulation systems that led to a shift from glacial interglacial climate. While polar ice cores attest an antiphased thermal pattern at millennial timescales, recent well-dated moraine records both hemispheres suggest in-phase fluctuations glaciers through T1, which is inconsistent with the bipolar see-saw paradigm. Here, we present glacier chronology based on 30 new 10 Be surface exposure ages well-preserved...
Abstract. Determining the timing and extent of Quaternary glaciations around globe is critical to understanding drivers behind climate change glacier fluctuations. Evidence from southern mid-latitudes indicates that local glacial maxima preceded global Last Glacial Maximum (LGM), implying feedbacks in system or ice dynamics played a role beyond underlying orbital forcings. To shed light on these processes, we investigated landforms shaped deposited by Lago Argentino (50° S), an outlet lobe...
Abstract. Determining the timing and extent of Quaternary glaciations around globe is critical to understanding drivers behind climate change glacier fluctuations. Despite synchronous ice-volume across hemispheres, evidence from southern mid-latitudes indicates that local glacial maxima occurred earlier in cycle, preceding global Last Glacial Maximum (LGM), implying feedbacks system or ice dynamics played a role beyond underlying orbital parameters. To shed light on these processes, we...
Abstract High‐mountain lake records in semiarid foreland settings, such as the central Andes of North‐western Argentina, are highly restricted and often deprived well‐preserved microstratigraphic information to analyze palaeoenvironmental changes their causes, particularly for periods prior Last Glacial Maximum. Laguna La Salada Grande (23°S/65°W, 4063 metres above sea‐level) is a closed shallow located at Cordillera Oriental, Argentina with unique depositional record, including geomorphic...
The surfaces of the icy satellites in outer Solar System show landforms and features that testify an intense geologic activity. Kilometric-scale tectonic structures shape majority their crusts showing complex patterns mostly refer to extensional strike-slip regimes. Such stress-related (i.e., fractures/faults) represent weakness zones provides insights dynamics mechanical properties crusts. Additionally, these are potential conduits for fluid propagation within can connect surface with...
ABSTRACT We describe and analyze the glacial geomorphology new 10 Be cosmogenic surface exposure ages from moraines deposited before Marine Isotope Stage (MIS) 2 around Nevado de Chañi (24°4′ S, 65°45′ W), a north–south‐trending massif located in arid subtropical mountains of northwestern Argentina. combine these data with previously published order to establish glacier chronology central Andes. The results show at least three phases expansions occurred global Last Glacial Maximum, (i)...
