Structural Modification of KAISiO4 Minerals [PDF]

open access: yes, 1997
Kalsilite, a polymorph of KAISiO4 is an end member of nepheline-kalsilite series and the mineral was syn-thesized by hydorhermal methods. The synthetic kalsilite is hexagonal, P63, with a=5.151(5), c=8.690(8) A.

Mineral consolidants

open access: yesProceedings of the International RILEM Conference Materials, Systems and Structures in Civil Engineering 2016 - Segment on Historical Masonry, 2016
Inorganic consolidants, such as ethyl silicate, nanolime and ammonium oxalate, have proven to be effective for certain materials, but each has its drawbacks. This has recently led to the investigation of hydroxyapatite (HAP) as a novel inorganic consolidant, which demonstrated excellent performance on carbonate stones.

Applicability of Earth Observation for Identifying Small-Scale Mining Footprints in a Wet Tropical Region

open access: yesRemote Sensing, 2017
The unpredictable climate in wet tropical regions along with the spatial resolution limitations of some satellite imageries make detecting and mapping artisanal and small-scale mining (ASM) challenging. The objective of this study was to test the utility

Clay minerals and sedimentary basin history [PDF]

open access: yes, 2005
Clay minerals in the mud and soil that coat the Earth's surface are part of a clay cycle that breaks down and creates rock in the crust. Clays generated by surface weathering and shallow diagenetic processes are transformed into mature clay mineral ...
