3D investigation and modeling of the geometric effects on porosity in packed beds

AIChE Journal, EarlyView.
Abstract In porous beds, physical boundaries restrict particle arrangement, leading to inhomogeneous porosity. This paper reports on the porosity profiles that are the result of geometric effects on monodisperse packed beds in cylindrical and cubic arrangements. Special focus is given to the influence of edges and corners in cubic geometries.

LA-ICP-MS Zircon U-Pb Isotopic Dating: Constraints on the Time of the Daoxiang Formation in North Fujian Province

Yankuang ceshi, 2014
Although there is poor outcrop in the area, the Daoxiang formation exposed in North Fujian has unique rock assemblage and metamorphism, and deformation characteristics show that the Daoxiang group does exist, and belongs to metamorphic rock of the ...

Geochemical discrimination of Early Palaeogene bauxites in Croatia

Geologia Croatica, 2012
Two discriminant function models were created in order to distinguish between major- and trace-element geochemical patterns typical of Lower Palaeogene (Palaeocene, Pc) bauxites formed on the portion of the carbonate platform comprising the Karst or ...

Data‐Driven Insights into Rare Earth Mineralization: Machine Learning Applications Using Functional Material Synthesis Data

Advanced Intelligent Systems, EarlyView.
Hydrothermal synthesis records for rare‐earth compounds are repurposed to learn mineralization rules. An extreme gradient boosting model ingests precursors, additives, and engineered descriptors to predict product phases, crystallization temperature, and pH. Feature importance indicates dominant thermodynamic control with kinetic modulation, suggesting

Potential for stratiform base-metal sulphides in SW England [PDF]

, 2004
The British Geological Survey (BGS) has recently re-evaluated the potential for stratiform base-metal sulphide mineralisation in Devon and east Cornwall (Rollin et al., 2001) (Figure 1). On the basis of their stratigraphy and tectonic setting the Lower
