Soil geomorphology of the eastern Sevilleta Long Term Ecological Research Site
… and base level drop. A rare association of sepiolite and palygorskite occurs in old soils formed in eolian fines. Pedologic and mineralogical data indicate that palygorskite formed by transformation of dust-borne, aluminum-rich minerals, and that sepiolite subsequently formed by …

Influencia de las adiciones puzolánicas en los morteros de restauración de fábricas de interés histórico-artístico
… MK-lime, OPC-lime, NHL, an MK-lime with sepiolite. Their physical-mechanical properties (density, porosity, absorption, strenghth, elasticity) were studied using hydrostatic balance, ultrasonic transmission, and loading with displacement registry by LVDT. Existing setting phases were …

Geology, mineralogy and geochemistry of the Cerro Matoso nickeliferous laterite, Córdoba, Colombia
… Saprolite zone. Pimelite, nimite and Ni-bearing sepiolite fill fractures in both the Upper and Lower Saprolite zones. Nickel averages 3% in the massive ore and ranges to as much as 7% locally. Nickel grades in fracture fillings range to as much as 30%. Variations in pH, and to a lesser extent Eh, …

Halloysite for smart nano-structured materials in sustainable applications
… co-assembling in water of cellulose nanofibers, sepiolite and halloysite nanotubes. The physico-chemical characterization of the resulting materials was carried out by SEM, X Ray Diffraction (XRD) and DMA analysis. Both the two nano-engineered hybrids were evaluated as functional delivery systems …
