Sulphide oxidation and carbonate dissolution as a source of CO2 over geological timescales
It is shown that enhanced sulphide oxidation coupled to carbonate dissolution can provide a transient source of CO2 to Earth’s atmosphere that is relevant over geological timescales and should be considered a potentially important but as yet generally unrecognized component of the long-term carbon cycle.
Glacial weathering, sulfide oxidation, and global carbon cycle feedbacks
Data is compiled showing that, as hypothesized previously, waters draining glaciers have solute chemistry that is distinct from nonglacial rivers and reflects different proportions of mineral weathering reactions, which supports the theory that glacial weathering is characterized predominantly by weathering of trace sulfide and carbonate minerals.
The hydrological regime of a forested tropical Andean catchment
The hydrology of tropical mountain catchments plays a central role in ecological function, geochemical and biogeochemical cycles, erosion and sediment production, and water supply in globally
Mixing as a driver of temporal variations in river hydrochemistry: 1. Insights from conservative tracers in the Andes‐Amazon transition
The response of hillslope processes to changes in precipitation may drive the observed changes in the solute geochemistry of rivers with discharge. This conjecture is most robust when variations in
Medicinal plants used by the Higaonon tribe of Rogongon, Iligan City, Mindanao, Philippines
This paper presents the ethnobotanical study conducted in Rogongon in Iligan City, Philippines on the indigenous medicinal plant utilization and healthcare practices among the Higaonon tribe.
Variations in Scale Morphology between Sexes of the Spotted Barb, Puntius Binotatus (Valenciennes, 1842) (Actinopterygii: Cyprinidae)
Scale morphology provides new and useful information for systematics. Scales have numerous hidden details in their structures that contribute effectively to fish identification and classification. A
Model predictions of long-lived storage of organic carbon in river deposits
Abstract. The mass of carbon stored as organic matter in terrestrial systems is sufficiently large to play an important role in the global biogeochemical cycling of CO2 and O2. Field measurements of
Paleoenvironmental and Paleoclimatic Interpretations of the Late Paleocene Goler Formation, Southern California, U.S.A., Based On Paleosol Geochemistry
The Paleocene was characterized by high global temperatures and elevated concentrations of atmospheric CO2. Paleoclimate records of this epoch are of particular interest to understanding the effects
