You
don't have to be a geologist to enjoy
our place. Everybody who will go down
the stairs into the crater, and also the
ones who stay at the top, are amazed of
the rockformations and the colors we get
here. Just pay attention to it. Enjoy!
Hereunder a comment of a profesional geologist
who visited us:
Quote:
Hi Will,
As promised, here are just few words about
columnar jointing in basalt that you can observe from your hotel right
behind the waterfall: columnar jointing forms in lava flows in most
cases, and is somewhat a rather rare feature. Columns are straight and
regular (but sometimes curved) with 4 to 7 faces (check the steps along
the steep track going down to the water fall!). It is commonly
interpreted as resulting from rapid cooling from the top downward, most likely
in the presence of water.
Below the columnar jointing unit is a different,
more altered (orange color is due to the presence of clay minerals
that forms during alteration) unit with bombs and scoriae. Unlike
columnar jointing, which result from effusion of basaltic lava, such
feature results from a more a explosive event that occurred prior to
eruption of columnar basalt.
These 2 units can be seen in the front page of
your brochure. Both deposits most likely results from the (extinct)
volcanic activity of the Porvenir Volcano.
Hope this helps - including this in your website
will attract thousands of Geologists! :-)
all the best.
