Elemental dissolution of basalts with ultra-pure water at 340°C and 40 MPa in a newly developed flow-type hydrothermal apparatus
hydrothermal system water–basalt reaction elemental dissolution flow-type experiment sub-terrestrial microbial ecosystem
2017/4/11
To simulate the discharge zone of hydrothermal systems in the laboratory, we developed a flow-type hydrothermal
apparatus that can reproduce water–rock reactions at elevated temperatures and pressure...
Pedogenic Formation of Kaolinite-Smectite Mixed Layers in a Soil Toposequence Developed from Basaltic Parent Material in Sardinia (Italy)
Basaltic Rock (Weathering) Kaolinite-Smectite Mixed Layers Sardinia Smectite-Layer Charge Soils
2011/12/7
Abstract: Formation of kaolinite-smectite (K-S) mixed layers in a soil toposequence developed from basaltic parent material was examined. The soil formed in a temperate climate with alternating dry an...

Abstract: A dusky red Oxisol forming on a tholeiitic basalt is found to contain varying proportion of aluminous hematite (Hm) and titanoaluminous maghemite (Mh) in the different size fractions. Maghem...
Hematite and Goethite from Duricrusts Developed by Lateritic Chemical Weathering of Precambrian Banded Iron Formations, Minas Gerais, Brazil
Hematite Goethite Laterite Mossbauer Spectrometry

Abstract: The upper 15–20 m of a 200 m thick lateritic weathering profile on Precambrian itabirites of Capanema, Brazil, reveals a genetic pathway for the formation of hematitic and goethitic nodules ...
Characterization and Genetic Interpretation of Clays in an Acid Brown Soil (Dystrochrept) Developed in a Granitic Saprolite
Soil clays Weathering Soil vermiculite Soil smectite Hydroxy-Al intergrades Chlorite Dystrochrept
2012/1/4
X-ray diffraction and chemical analyses were performed on clay fractions separated from an acid brown soil (Dystrochrept) by means of size fractionations using high-gradient magnetic separation techni...
