The first 25 years of satellite carbonate sedimentology: What have we learned?
The Depositional Record, EarlyView.Observations of the suspension and transport of carbonate sediments from reefs, banks and shallow shelves have been made by satellite instruments for ca 25 years. With an increasing number of instruments in space, providing advanced observational capabilities, remarkable insights have been gained concerning carbonate sedimentological processes. Details

An integrated mineralogical, petrographic, light stable isotope and noble gas investigation of Sahara 99201 ureilite [PDF]
, 2001 New ureilite Sahara 99201 has been investigated to determine mineralogy, petrography, light stable isotopes and noble gases. The sample is a typical olivine pigeonite ureilite (Fo 78, Wo 10, En 72).

The importance of mineralogical knowledge in the sustainability of artisanal gold mining: a mid-south Peru case [PDF]
, 2019 Mineralogy and gold processing techniques from several mining areas of the Nazca-Ocoña gold belt, Mid-South Peru, were investigated to assess the efficiency of gold extraction methods in relation to their mineralogy.

Water pathways and ancient lakes: Flowing towards new models to unravel the past
The Depositional Record, EarlyView.Abstract Significant progress has been made in understanding lake basin evolution through climatic and tectonic changes using sedimentology, sequence stratigraphy, geochemistry, hydrology and watershed characteristics to interpret three main lake basin types: overfilled, balanced‐fill and underfilled, including fluvio‐lacustrine systems.

The Depositional Record, EarlyView.The article demonstrates that brine was central for the supply of Ca and B to the studied saline lake. The ion transport occurred probably by thermal springs, while contributions from surface waters cannot be excluded. However, the saturation and syndepositional precipitation of Ca borates were initiated by an arid climate through evaporation, while ...

The Depositional Record, EarlyView.Despite advanced wastewater treatment, dilution by rainwater and mixing, and microbial modification, nitrogen nutrients derived from shallowly injected wastewater are detected in nearshore waters in the Florida Keys. Abstract Injection of treated wastewater into the shallow subsurface on islands and along coastlines is a common practice in areas like ...

The Depositional Record, EarlyView.Halite thickness in Mbr 2 of the Kumugeliemu can reach 1000 m. The thick halite is associated with sedimentary rock with shallow water fabrics. The thick halite was formed in a shallow‐sea water environment. The ‘Multiple transgression‐salt‐forming’ model was established.
