Varying effects of stream restoration on riparian soil carbon persistence and methane emissions in the southern Rocky Mountains, United States

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Channel incision can disconnect streams from their floodplains, potentially depleting carbon (C) in riparian soils by stimulating microbial decomposition. Stream restoration may offer an opportunity to replenish soil C pools by saturating riparian soils with water and slowing microbial activity.

‘Chrystalline Talk’: Thomas Browne's Poetics of Concretion and Mineral Plain Style

open access: yesRenaissance Studies, EarlyView.
ABSTRACT This article charts the figuration, both material and rhetorical, of mineral bodies in early modern natural philosophy, paying particular attention to the second book of Thomas Browne's Pseudodoxia Epidemica (1646). It argues that concretions (stony calculi and crystals formed through the aggregation of physical matter) make manifest a mineral

Properties of thermally recycled basalt fibres and basalt fibre composites

open access: yes, 2018
The reduction to the tensile failure stress caused by high-temperature incineration of basalt fibres is investigated. The failure stress of single basalt fibres and tows decreases rapidly with increasing temperature when heated above ~ 250 °C, and at ...

Sedimentology of silica granules and haematite in the 3.47 Ga Antarctic Creek Member, Mount Ada Basalt, Western Australia

open access: yesSedimentology, EarlyView.
ABSTRACT The Paleoarchean Antarctic Creek Member of the Mount Ada Basalt, Eastern Pilbara Terrane, Western Australia, includes beds of jasper and white chert composed of sand‐sized silica granules that often contain or are mixed with silt‐sized particles of haematite.

Source‐to‐sink sediment transport reversals during glacial sea‐level lowstands sustain soil formation on pericoastal carbonate terrains

open access: yesSedimentology, EarlyView.
ABSTRACT Understanding the processes that drive soil formation is crucial for developing sustainable land‐use strategies, as changing land‐use practices and climate change exacerbate soil erosion. The formation of substantial arable soils on carbonate bedrock requires substantial dust accretion as the underlying bedrock lacks siliciclastic material. In

Emergence of Continents Stabilized the Bioavailability of Boron

open access: yesTerra Nova, EarlyView.
ABSTRACT Boron is an essential element for the development of life on Earth; borates stabilize ribose in prebiotic reactions and facilitate metabolism in higher plants. There is, however, a relatively narrow surface boron concentration range over which borates stabilize and serve as a micronutrient rather than a toxin.
