Spatial variation analysis of soil organic matter in karst area

open access: yesCarsologica Sinica, 2022
As an important parameter for soil quality assessment, soil organic matter (SOM) can provide nutrients for crops, strengthen soil fertility, and improve soil physicochemical properties.

Comparative Binding Studies of the Chelators Methylolanthanin and Rhodopetrobactin B to Lanthanides and Ferric Iron

open access: yesChemBioChem, EarlyView.
The synthesis and the investigation of the lanthanide (Ln) and Fe‐binding properties of the putative lanthanophore methylolanthanin (MLL) and the siderophore rhodopetrobactin B (RPB B) are reported. While both chelators bind Lns, they unexpectedly precipitate with Lns under biologically relevant conditions and thereby challenge the proposed classic ...

Mechanisms of near‐normal sea water dolomitisation: Mesohaline‐reflux or syn‐depositional?

open access: yesThe Depositional Record, EarlyView.
This study investigates the dolomitisation of the Eocene Dammam Formation on the Arabian Plate using petrographic, mineralogical, geochemical and isotopic analyses. The findings reveal two distinct dolomite types, formed primarily through normal‐to‐mesohaline sea water dolomitisation, challenging previous models such as sabkha‐meteoric mixing.

Linking PAHs concentration, risk to PAHs source shift in soil and water in epikarst spring systems, Southwest China

open access: yesEcotoxicology and Environmental Safety, 2023
A systematic assessment of the variations in the ecological risk of PAHs and the key emission sources controlling the variations is of great importance to human health and aquatic organisms. PAH concentrations, composition, source, and ecological risk in

Evaporite karst geohazards in the Delaware Basin, Texas: review of traditional karst studies coupled with geophysical and remote sensing characterization [PDF]

open access: yes, 2017
Evaporite karst throughout the Gypsum Plain of west Texas is complex and extensive, including manifestations ranging from intrastratal brecciation and hypogene caves to epigene features and suffosion caves.

In-situ cosmogenic 36Cl denudation rates of carbonates in Guizhou karst area [PDF]

open access: yes, 2013
This study quantifies surface denudation of carbonate rocks by the first application of in-situ cosmogenic <sup>36</sup>Cl in China. Concentrations of natural Cl and in-situ cosmogenic <sup>36</sup>Cl in bare carbonates from ...

Carbonate sedimentology: An evolved discipline

open access: yesThe Depositional Record, EarlyView.
Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

On the value of water quality observations for karst model parameterization [PDF]

open access: yes, 2017
If properly applied, karst hydrological models are a valuable tool for karst water resources management. If they are able to reproduce the relevant flow and storage processes of a karst system, they can be used for prediction of water resources ...
