The Material Basis of 18th‐Century Meissen Porcelain

Archaeometry, EarlyView.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Clay mineralogy and diagenesis of the Recent-Pleistocene volcanogenic sedimentary sequence of the Mexican Basin

Revista Mexicana de Ciencias Geológicas, 2018
Diagenesis of the Recent-Pleistocene volcanogenic depositional sequence of the Mexican Basin developed, in the gravel and sand strata, kaolinite, interstratified kaolinite/2H2O-smectite, opalC, 1H2O and 2H2O-smectite and Si-contaminated smectite ...

Chemically modified smectites [PDF]

Clay Minerals, 2003
AbstractThis paper summarizes recent results obtained on chemical modifications of smectites. These include replacement of exchangeable cations with protons, a process connected with smectite autotransformation – attack of protons on the layers and liberation of central atoms from the octahedral and tetrahedral sheets, causing modification of the acid ...

Controlled Synthesis of Carbon-Encapsulated Copper Nanostructures by Using Smectite Clays as Nanotemplates [PDF]

, 2012
Rhomboidal and spherical metallic-copper nanostructures were encapsulated within well-formed graphitic shells by using a simple chemical method that involved the catalytic decomposition of acetylene over a copper catalyst that was supported on different ...

Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

Decoding the origins and sources of clay minerals in the Upper Cretaceous Tununk Shale of south‐central Utah: Implications for the pursuit of climate and burial histories

The Depositional Record, 2020
Clay minerals in fine‐grained marine sedimentary successions are most commonly considered to be detrital in origin and have been used extensively by geologists as indicators of palaeoclimate conditions in the hinterland.

Boron enrichment in Martian clay [PDF]

, 2013
We have detected a concentration of boron in martian clay far in excess of that in any previously reported extra-terrestrial object. This enrichment indicates that the chemistry necessary for the formation of ribose, a key component of RNA, could have ...

The making of pure quartzose sand in continental interiors: Paraná River (Brazil and Argentina)

Sedimentology, EarlyView.
ABSTRACT As part of a comprehensive project on sedimentary processes in South America, this study focuses on sediment generation in the intracratonic Paraná Basin and monitors the evolution of sand composition along the Paraná River from central Brazil to the Río de la Plata estuary in Argentina.
