For any adventure
enthusiast, exploring diverse natural formations is a matter of pride and
satisfaction. While many of us are not able to explore the world, some people
make sure that they travel around the globe and find new tracks and trails to
explore. Australia is one destination that attracts as many adventure lovers as
urban and business tourists. Such is the popularity of the continent among
hikers and explorers that many guides, like best desert & savannah tracks atlas and
guide, have
become international bestsellers. Here are the geological and geographical
formations in the Savannah region of Australia that any nature lover would be
thrilled to explore.
- The
plateau region on the west
This region lying in the tropical savannahs is
more or less flat, with distinct zones of rugged formations along the coastal
side. Destinations like Hamersley Range and Kimberley attract many hikers and
explorers who carry out expeditions to know about the unique geological
timeline of these formations.
- The
Lowlands in the centre
Stretching from the Northern edge of the Gulf of
Carpentaria, all the way to the Murray-Darling plains, via the Great Artesian
Basin, this region is classified as flat lowlands. The geography of this region
is marked by sedimentary rocks that serve a water-retaining function before the
water flows to the eastern side of the continent.
- The
Highlands on the east
Almost the entire belt on the eastern edge of
Australian Savannah consists of a series of tall and very steep plateaus
running adjacent to the coastline. The slope of these plateaus gently merges
with the inland. The Northern regions of these plateaus have the Savannah belt.
These three distinct
regions are well-explained in stalwart illustrated books like best desert & savannah tracks atlas and guide. In addition, geologists are particularly interested in
some land formations that are only found in Savannah region, along with the
tropical belt surrounding it. These regions are described as follows:
- The
Peneplains
Erosion and weathering of mountains over
thousands of years gave rise to very flat and low lying formations known as
peneplains. These plains then accumulated limestone deposits, and stromatolites
grew here. Currently, it is a treasure chest for the mining industry.
- The
Greywackes
Another distinguished formation in Savannah
region is the sequence of rocks formed as a result of avalanches that happened
underwater. These also comprise volcanoes.
- Volcanic
lava and basalt
The massive deposits of basalt and volcanic lava
in the region around of Victoria River are reminiscent of the Cambrian age that
happened hundreds of millions of years ago. Consequently, this region present
marvels to geologists and earth scientists. These deposits eventually gave rise
to fertile soil on which flora thrived.
- Sandstone
deposits
Intriguing sandstone deposits, that are highly
resistant to erosion and weathering are also present in the Savannah. Their
horizontal deposition and their composition (mainly quartz) are responsible for
their amazing resistance to weathering.
The Savannah is a
treasure trove for geological scientists and earth science researchers. Books
and guides such as best desert & savannah
tracks atlas and guide describe the
fine details of the geographical and geological features of the region.
What a neat region to visit and so educational.
I haven't been there in a LONG time. Such a pretty city!
