Assembling for Water: The Prefigurative Politics of Land Futures in Argentina

open access: yesAntipode, EarlyView.
Abstract As in other areas of Argentina, residents from the Norte Neuquino in the northwestern reaches of Patagonia are concerned about the recent advancements of extractivism onto their territories. Their analysis is clear: the environmental crisis is directly linked to a democratic one, and they engage in a wide range of actions to envision and enact

Ultra-shallow-marine anoxia in an Early Triassic shallow-marine clastic ramp (Spitsbergen) and the suppression of benthic radiation [PDF]

open access: yes, 2015
Lower Triassic marine strata in Spitsbergen accumulated on a mid-to-high latitude ramp in which high-energy foreshore and shoreface facies passed offshore into sheet sandstones of probable hyperpycnite origin.

Non‐visible aspects of ceramics: Archaeological science approaches in Andean pottery studies

open access: yesArchaeometry, EarlyView.
Abstract This article examines the history of the application of archaeological science in studies of pre‐Hispanic pottery from the Andes, South America, through academic publications from the 1960s to the present. It details the questions addressed by, analytical tools used for and theoretical underpinnings of investigations into provenance and ...

New insights into one of the oldest glacial deposits in the northern Alpine foreland (Höchsten, SW Germany)

open access: yesBoreas, EarlyView.
Diamictic deposits within a presumed Early Pleistocene overdeepened basin are investigated with a combined sedimentological‐geotechnical approach including analysis via μCT scans. Sedimentary facies, geotechnical properties, and microstructures reflect a transition from glacier‐proximal deposition towards direct ice contact and subglacial deformation ...
