The quarry operators at Wagholi have sought to exploit the aa sill as intensively as possible while not wasting money and time on the underlying pahoehoe
As you get nearer the flow, the pali becomes steeper and high walls of pahoehoe
block your view.
lava flows appear to look like shiny, smooth ribbons of cake batter.
is the hottest and most fluid of any type of lava; it has been compared to hot fudge poured from a pan.
This hypothesis is supported by data of Chadwick and colleagues who observed changes in soil mineralogy across a steep precipitation gradient on a 170 000-yr-old pahoehoe
flow of Hawi Volcanics (Chadwick et al.
High temperature pahoehoe
flows near vents have smooth "ropey" surfaces (Williams and McBirney, 1979, pp.
Some poorly crystallized specimens have a habit resembling ropy lava or pahoehoe
, with well-developed crystals extruding out along the ridges of the "flow."
Hawaiian volcanoes produce two kinds of lava, a smooth lava called Pahoehoe
(pronounced pah HOH ee hoh ee) and a rough form called `A'a (pronounced AH ah).
Fountaingrass establishes locally in depressions in the pahoehoe
lava where well-drained lithosolic soil has developed, and along small cracks and fissures.
