Rhenium Isotopes Record Oxidative Weathering Intensity in Sedimentary Rocks

Geochemistry, Geophysics, Geosystems
Oxidative weathering of organic carbon in sedimentary rocks is a major source of CO2 to the atmosphere over geological timescales, but the size of this emission pathway in Earth's past has not been directly quantified due to a lack of available proxy ...

Assessing the Impact of Weather on Traffic Intensity [PDF]

Weather, Climate, and Society, 2010
Abstract This paper focuses on the effect of weather conditions on daily traffic intensities (the number of cars passing a specific segment of a road). The main objective is to examination whether or not weather conditions uniformly alter daily traffic intensities in Belgium, or in other words whether or not road usage on a particular ...

Intensive Chemical Weathering in the Arctic During the Miocene Climatic Optimum [PDF]

Palaeogeography, Palaeoclimatology, Palaeoecology, 2023
The Arctic today has shallow, chemically immature, and frost-dominated weathering regimes. At Sokli, Finland (68°N), a 70 m deep palaeo-weathering profile is developed in a Devonian carbonatite pipe that represents fundamentally different past weathering environments.

No impact of weather conditions on the outcome of intensive care unit patients [PDF]

Wiener Medizinische Wochenschrift, 2021
SummaryGlobal warming leads to increased exposure of humankind to meteorological variation, including short-term weather changes. Weather conditions involve changes in temperature, heat and cold, in air pressure and in air humidity. Every single condition influences the incidence and mortality of different diseases such as myocardial infarction and ...

Effects of climatic variation on weathering intensity for the mineral composition in some Iraqi soils [PDF]

Caspian Journal of Environmental Sciences, 2022
This study was conducted to find out the effect of variation in the nature of climatic conditions and physiographic location on the weathering intensity of the mineral composition in some Iraqi soils. Six different locations were selected within rainfall

Constraints of weathering intensity in different climate zones on coal accumulation environment. [PDF]

Sci Rep
Abstract There are currently multiple hypotheses regarding coal accumulation models, each with certain limitations in applicability. This article investigates the relationship between modern sedimentation, soil and climate to analyze the distribution of coal across different geological periods, aiming to explain the coal accumulation ...
