South Asian monsoon history over the past 60 kyr recorded by radiogenic isotopes and clay mineral assemblages in the Andaman Sea [PDF]

, 2015
The Late Quaternary variability of the South Asian (or Indian) monsoon has been linked with glacial‐interglacial and millennial scale climatic changes but past rainfall intensity in the river catchments draining into the Andaman Sea remains poorly ...

Influence of presence of ammonium in the hydrothermal illitization of smectite [PDF]

, 2017
During diagenesis, several reactions induce changes both in phyllosilicates and organic matter, which in basins associated to the production of hydrocarbons leads to ammonium fixation in illite and micas [1] and to dissolution induced by organic acids [

Phase IIb Trial for the Palliative Treatment of Patients With Primary Hepatic Malignancy Unable to Receive Curative Treatment: Efficacy of Colchicine

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This trial was to evaluate the efficacy and the safety of colchicine for the palliative treatment of patients with primary hepatic malignancy unable to receive curative treatment. Forty hepatocellular carcinoma (HCC) patients and two intrahepatic cholangiocarcinoma (ICC) patients signed the informed consents.

Towards an understanding of thermodynamic and kinetic controls on the formation of clay minerals from volcanic glass under various environmental conditions [PDF]

, 1996
lmogolite is the kinetically and thermodynamically favoured weathering product from rhyolitic volcanic glass in the soil-forming environment. However, on thermodynamic grounds imogolite would also appear to be the favoured alteration product of rhyolitic

Contaminants of emerging concern in agricultural soils: Current understanding, overlooked issues, and future priorities

PLANTS, PEOPLE, PLANET, EarlyView.
Contaminants of emerging concern (CECs) in agriculture represent a growing global challenge for food safety and public health. In this review, we synthesized evidence on how substances such as pharmaceuticals, microplastics, and per‐ and polyfluoroalkyl substances (PFAS) enter soils, accumulate in crops, and affect ecological and human health. We found

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Composition of Smectite from Maastrichtian Sediment of the Afikpo Basin, southeast Nigeria

Journal of Applied Sciences and Environmental Management, 2019
The sand, silt, shale and clay fractions soils derived from Maastrichtian sediments in the Afikpo Basin, southeastern Nigeria exhibit unusually high cation-exchange capacities. Smectite was identified by X-ray diffraction in all sample fractions and was

Adsorption of Imidazolinone Herbicides on Smectite−Humic Acid and Smectite−Ferrihydrite Associations

Journal of Agricultural and Food Chemistry, 2001
Adsorption of imazapyr (IMZ), imazethapyr (IMZT), and imazaquin (IMZQ) was studied on two smectite-humic acid and two smectite-ferrihydrite binary systems prepared by treating a Wyoming smectite with a humic acid extracted from soil (4 and 8% w/w of the smectite) and with just-precipitated synthetic ferrihydrite (8 and 16% w/w of the smectite ...
