Magnetic fabrics of tephrite lava flow at Vrbička locality (Doupov Volcanic Complex)
This paper summarizes the results of application of the anisotropy of magnetic susceptibility in tephrite lava flow in the Vrbička quarry (Doupov Volcanic Complex). This method was applied in order to determine the sense of the ...

Stream directions of the late-Palaeozoic andezitoidic lava flows of the Krkonoše Piedmont Basin and the localisation of their volcanic centres.
Assumed volcanic centres were localized in the Krkonoše Piedmont Basin as the result of a method based on measuring the long axes of the ellipsoidic vesicles of the basaltandesitic flows. Different directions of individual lava ...

Velký Roudný - animation
Eruption history of Velký Roudný Volcano is shown in the near-realistic 3D animation. Assymetric scoria cone emitted two main lava flows. The second lava flew into the Moravice river canyon. Interaction of the hot lava...

Alteration of the low-rank coal by basaltic lava flows on the Faroe Islands
This study characterizes alteration effects on low-rank coal on the Faroe Islands. The basalt lava flows covering the coal-bearing layer caused either slight thermal alteration of the coal surface, but without total elevation of the...
