Using [delta] ph as a geochemical index of illite neoformation in saprolite [PDF]
, 2008 Sal pH is routinely measured for agronomic purposes. When the difference between KCI pH and H2O pH, or ApH, yields positive values, it is used by soil scientists as a classification criterion for identifying anionic subgroups according to the Soil ...

Chemical weathering and provenance evolution of Holocene–Recent sediments from the Western Indus Shelf, Northern Arabian Sea inferred from physical and mineralogical properties [PDF]
, 2012 We present a multi-proxy mineral record based on X-ray diffraction and diffuse reflectance spectrophotometry analysis for two cores from the western Indus Shelf in order to reconstruct changing weathering intensities, sediment transport, and provenance ...

Journal of Public Pedagogies, 2019 We propose weather wanderings as a critical and postdevelopmental intervention (Blaise, 2010) into a developmentally appropriate or child-centred approach to walking. A developmentally appropriate approach emphasises an autonomous, white, able-bodied, middle-class, and developing boy child that discovers and explores the natural world as an external ...

The distribution of evaporitic weathering products on Antarctic meteorites [PDF]
White evaporite deposits of terrestrial origin occur on some 5 percent of Antarctic meteorites. The few previous studies, and new mineralogical analyses, indicate that the deposits are predominately carbonates and/or sulfates of magnesium.

Simulation of sandstone degradation using large-scale slake durability index testing device [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2012 Large-scale slake durability index tests have been performed on Khok Kruat (KK), Phu Kradung (PK) and Phra Wihan(PW) sandstone. A rotating drum with a diameter of 64 cm and length of 40 cm was fabricated to accommodate ten rockfragments with a nominal ...
