High-resolution 3D analyses of the shape and internal constituents of small volcanic ash particles: The contribution of SEM micro-computed tomography (SEM micro-CT)

Vonlanthen, Pierre ; Rausch, Juanita ; Ketcham, Richard A. ; Putlitz, Benita ; Baumgartner, Lukas P. ; Grobéty, Bernard

In: Journal of Volcanology and Geothermal Research, 2015, vol. 293, p. 1–12

The morphology of small volcanic ash particles is fundamental to our understanding of magma fragmentation, and in transport modeling of volcanic plumes and clouds. Until recently, the analysis of 3D features in small objects (< 250 μm) was either restricted to extrapolations from 2D approaches, partial stereo-imaging, or CT methods having limited spatial resolution and/or accessibility. In...

Growth mechanism of snowball garnets from the Lukmanier Pass area (Central Alps, Switzerland): a combined μCT/EPMA/EBSD study

Robyr, Martin ; Vonlanthen, Pierre ; Baumgartner, Lukas P. ; Grobéty, Bernard

In: Terra Nova, 2007, vol. 19, no. 4, p. 240-244

For two decades, considerable efforts have been made to explain the formation of snowball garnets by either the rotational or non-rotational models. On the basis of morphological, chemical and crystallographic evidence, this paper presents new data on snowball garnets showing that the formation of these microstructures can be explained by the combination of the two previously proposed mechanisms...

X-ray computed micro tomography as complementary method for the characterization of activated porous ceramic preforms

Vasic, Srdan ; Grobéty, Bernard ; Kuebler, J. ; Graule, T. ; Baumgartner, Lukas P.

In: Journal of Materials Research, 2007, vol. 22, no. 5, p. 1414-1424

X-ray computed micro tomography (CT) is an alternative technique to the classical methods such as mercury intrusion (MIP) and gas pycnometry (HP) to obtain the porosity, pore-size distribution, and density of porous materials. Besides the advantage of being a nondestructive method, it gives not only bulk properties, but also spatially resolved information. In the present work, uniaxially pressed...
