Block Lava Magmas of felsic, SiO2-rich (e.g., andesitic, da- citic, or rhyolitic)
composition are more strongly polymerized and therefore more viscous. Such
lavas can never form pahoehoe structures. The slightly more mafic, SiGVpoor,
andesitic, ...

The Emplacement of Silicic Domes and
Lava Flows
The volcanic activity has consisted of endogenous extrusions, block-lava flows,
Merapi-type block and ash flows, vertical pyroclastic eruptions, and lahars. Since
1960, block-lava flows have been volumetrically more important than ...

Geological Hazards: Their Assessment, Avoidance and Mitigation
Although the term 'block lava' refers to lavas with fragmented surfaces, it is
usually restricted to those flows in which the fragments are much more tegulat in
shape than are those of aa flows. Most of the flows of otogenic regions are of
block ...

Block Lava Flows Aa flows grade into another type known as block lava flows,
which have much the same structure as that of aa flows, but the upper and lower
fragmen- tal parts of the flow, instead of consisting of very irregular jagged pieces

Volcanoes: Global Perspectives
Spiny fragments can be found in some block lava flows, however, and some
smooth blocks can be found in many spiny 'a'a flows. Many flows consisting of
conventional spiny 'a'a throughout most of their length become blocky near their
distal ...

Block lava flow, Atacama, Chile. The sharp-edged fully angular shape of the

Basaltic andesites may occur as aa lavas, but when andesites do occur as lava
flows, the typical form is as block lava (Figure 4-22). These flows are commonly
tens of meters thick and consist of smooth blocks of andesite meters across.
Harvey Blatt, Robert J. Tracy, Brent Owens, 2006
Andesitic lava's high viscosity generates block lava flows, which are similar to,
but coarser, than aa lava. Block lava consists of smoothsided blocks up to several
meters in diameter that tumble downslope (Figure w). Block lavas Iithify as ...
