Falha da Penha 2 Urucum
From Serra do Amolar
On the right bank of
Upper Paraguay river,
to Ilha de Ínsua from Fazenda da Penha (north of Amolar)
to
Ilha de Ínsua (north of Lagoa Gaíba); partly
buried near Ilha de Ínsua by sediments of
Pantanal formation; 60 km long; arkosic
sandstones of the Urucum formation.
Falha da Lagoa 2 Urucum,
From Serra do Amolar
On the right bank of
Upper Paraguay river,
Bocaína
to Lagoa Gaíba
in a direction parallel to Falha
da Penha, west
of Serra do Amolar and Ilha de Ínsua;
partly covered by waters of Lagoa Gaíba;
may prolong to southeast reaching Morraria de
Novos Dourados; 55 km long; arkosic
sandstones and calcareous dolomites of the
Urucum and Bocaína Formations, respectively.
Urucum,
Along the valley of
Between Morro do

Urucum and Morraria do
Santa Cruz Córrego Band'Alta Rabichão; mostly buried by
sediments of
Pantanal formation.

Table 11. Geomorphic subunits of the Pantanal of Mato Grosso.1
_________________________________________________________________________
__________________________________
Subunit
Description
_________________________________________________________________________
__________________________________
Cordones2, or small ranges
Positive relief forms, narrow and
elongated, protruding slightly above the level
(cordilheiras 3)
of the surrounding terrain. Their
shape and location suggests that they may be
relics of a much more active geodynamical past.
Channels with permanent runoff
Negative relief forms of sizable depth,
with permanent or quasi-permanent
runoff, such as the major and minor rivers of the
Pantanal.
Channels with temporary runoff
Negative relief forms, shallow and more
or less narrow, with temporary
(corregos, or corixos3)
(intermittent) runoff.
Streambeds with temporary runoff
Negative forms of relief,
slightly concave and quite wide and shallow, with
(vazantes3)
relatively mild longitudinal slopes.
Depressed plains
Generally flat and of negligible
relief, typically occupying interfluvial locations
and subject to more-or-less seasonal inundation.
Flooded plains
Positive forms of relief which are subject
to seasonal inundation from
neighboring channels.
Diffuse flooded plains
Flooded plains where runoff lacks a
clear direction.
Composite flooded plains
Flooded plains where runoff may or may
not have a clear direction. Typical of
this subunit is the runoff of the lower courses of
the Cassange, Alegre,
Caracará, and Cuiabá rivers, right-bank
tributaries of the Upper Paraguay
river (downstream of Bela Vista do Norte and
upstream of Amolar).

Subunit
Description

__________________________________
Lagoons
Negative forms of relief, sometimes of sharp
concavity, which may be
(baías3)
permanently or temporarily filled with
water; saline at times. The greatest
density of this subunit is found in the area of
Nhecôlandia.
Isolated hills
Extremely positive relief forms, associated
with underlying Precambrian and
(inselberg, or island hills)
Cambrian rocks, and occupying
relatively small areas within the Pantanal
depression. Examples are the Ilha de Ínsua, Morro
do Conselho, Morro de
Coimbra, and Fecho dos Morros.

4 Measured from upstream station.
5 Based on channel length and minimum observed water levels, calculated
from Table 2. 6 If not shown, not precisely definable.
7 Small portion cannot be precisely defined. 8 Estimated by linear
extrapolation from measured values at Porto Murtinho and Fecho dos
Morros.
