The Appalachian Plateau located in the northwest
region of Georgia is a series of plateaus dissected into
deep, narrow valleys and steep, rugged mountain
sides. Maximum elevations are over 4000 feet.

Appalachian Plateau

Main types of rocks: Sedimentary rocks of similar age
and type to those found in the southeast. Igneous rocks are
also found there. Examples of these rocks are limestone,
sandstone and black shale.
How the rock formed: Sediment from nearby eroding hills
flowed into a basin called the Ocoee. Over millions of
years, sediments deposited and transported by water
compressed into the high-calcium limestone, dolomite and
silica bedrock of the southern Appalachians. The igneous
rocks were formed from the molten lava.
Rock and the mineral resources for this region:
Sedimentary rocks contain minerals such as pyrite and
metallic copper.
Igneous rocks contain minerals like pegmatite, alaskite,
mica and feldspar. Also found are iron ore, coal fuel.
Fossils: The fossils found belong to the Paleozoic era and
were deposited in shallow seas between the Cambrian and
Pennsylvanian periods (540-300 million years ago). The
rocks of the Appalachian Valley contain a variety of shark
fossils that include tertiary shark teeth, goblin shark,
mackerel, tiger shark and sand shark as well as the
Carcharodon megalodon shark can be found in the southern
regions of the Appalachian Mountains.

Types of rocks/minerals and fossils

During the middle Ordovician Period (about 440 - 480
million years ago), the tectonic plate carrying this area
collided with another plate, leading to the creation of a
new seduction zone and the beginning of the
Appalachians As a result of this and later progenies,
alternating beds of hard and soft Paleozoic sedimentary
rocks were folded, looking much like the wrinkles one
would find in a kicked floor rug.

Valley and Ridge

The Valley and Ridge are located in the
northwest region of Georgia and are bordered by
the Appalachian Plateau, Blue Ridge and
Piedmont regions.

Exhibit
Valley and Ridge

Main types of rocks: Sedimentary rocks in these areas
occur as layers (also called strata) and consist mainly of
sandstones, shale, limestone, and dolostone. The major
ridges are formed by prominent sandstone. The valleys
and lower flanks of major ridges are underlain by shale
and limestone.
Explain how the rock formed: The Sedimentary rocks
originally were deposited in horizontal layers, but in the
Valley and Ridge area these layers have been folded and
faulted, squeezed and deformed by the continental
collision event. As a result, the layers are no longer
horizontal but are bent into great folds. As these bent and
folded layers of rock gradually weather and erode, they
form the long winding ridges and valleys from which the
region takes its name.
Ridges are developed on resistant layers of sandstone.
Valleys are underlain by shale or limestone. Limestone
and Dolostone contain the minerals calcite and
dolomite.
Fossils: Many of these rocks contain many marine
fossils like Brachiopods (clams and mollusks) and
Trilobites.

When North America and Africa collided to make the
Pangaean supercontinent, the compression where they
met shoved sheets of sedimentary rock over each other
to make the Valley and Ridge. The Paleozoic
Sedimentary rocks of the Valley and Ridge formed
under a vast, shallow, inland sea that covered the area.

Canyon State Park, just east of Trenton.

Piedmont

The Piedmont is located in the central part of Georgia.
It is flat and hilly along with some prairies. The capital
Atlanta is located here along with other major cities in
Georgia. This makes it a very popular tourist attraction.
Return to
Exhibit
Piedmont

Main types of rocks: The rocks of the Piedmont are
igneous and metamorphic that include granite, gneiss,
schist, slate.
Explain how the rock formed: Several periods of
volcanism have occurred, and the sedimentary rocks
have been intruded by magma from deeper layers of
the Earth, forming the granitic rocks. The metamorphic
rocks were formed by the heat and pressure from the
other rocks.
Rocks typical of the region include Gneiss (Feldspar,
quartz and mica), schist (contains talc, chlorite, quartz,
and feldspar), amphibolite, migmatite, and granite
(Feldspar, quartz and mica).
Fossil types: The rocks of the Piedmont are largely
metamorphic and igneous, though many of them were
initially sedimentary and may have contained fossils
from Paleozoic continental seas. Some still contain
fossils, but the fossils have been deformed by stress
and strain on the rocks. The most common fossils are
those of fishes, plants, and footprints, though remains
of large reptiles like phytosaurus and rauisuchians are
also known.
Return to
Exhibit

The Piedmont geological region is composed of
igneous and metamorphic rocks resulting from ancient
(300 to 600 million year old) sediments that were
subjected to high temperatures and pressures and re-
exposed about 250 to 300 million years ago.

Coastal Plains

The Coastal Plains are located in the Southern part of
Georgia. It is split into the Upper Coastal Plain
(agricultural part) and Lower Coastal Plain (Atlantic
Ocean and swamps).

Coastal Plains

en.wikipedia.org
Main types of rocks: The Coastal Plain is composed of
sedimentary rock layers. Sand, gravel, clay, and peat are found
here.
Explain how the rock formed: Formed from rock sediments.
The fall line marks the beginning of the Coastal Plains. It has
waterfalls and rapids that formed where streams flow off the
hard, erosion-resistant rocks of the Piedmont onto the softer,
easily eroded sediments of the Coastal Plain.
Rock and the mineral resources for this region: The central
and eastern Coastal Plain has important kaolin clay deposits.
These deposits derived from the intense weathering of Piedmont
rocks like granite and gneiss were formed during the Paleocene
period. These rocks contain the mineral feldspar, the chemical
weathering of which produces kaolin clay. Also found are
Bauxite, sand, limestone. Main mineral resource is Kaolin.
Fossils: Further south, Coastal Plain strata contain fossil-
bearing sediments that formed in the shallow offshore waters of
the continental shelf. Clams, snails, cephalopods, corals, sea
urchins, and sand dollars are common, as are shark’s teeth,
including those of the giant shark megalodon.

Exhibit

Sedimentary deposits formed during the
Pleistocene epoch, or Ice Ages and were deposited
by ancient seas and river deltas that periodically
dominated the landmass over the last 120 million
years. Their history involves the rising and falling
of sea level due to the advance and retreat of the
giant continental glaciers.

The Blue Ridge Mountains in northeast Georgia
make up the state's highest mountain range. The
range of rugged ridges and rounded, weathered
peaks varies in elevation from 1,600 to 4,700
feet and harbors spectacular mountain scenery,
as well as some of the world's richest biological
diversity. In addition, the range contains
Georgia's wettest areas, with higher elevations
getting more than eighty inches of rain annually
on average.

Blue Ridge

activerain.com
Main types of rocks: The rocks in the Blue Ridge
province are dominantly metamorphic and consist of
greenstone (metabasalt), schist, and slate. Granite
and other igneous rocks also are found throughout
the area.
Explain how the rock formed: The processes
include rock folding, faulting, upward thrusting, and
a great collision that took place about 300 million
years ago between the North American and African
continents in a process called plate tectonics. The
collision buckled the Earth's surface and pushed
huge masses of rocks westward, causing them to pile
up.
The rocks of the Blue Ridge Mountains, have a
crystalline foundation. The layered gneiss contains
various amounts of biotite, muscovite, quartz and
feldspar. They also contain small amounts of mica
schist and larger amounts of hornblende. The non-
layered gneiss is mostly quartz monzonite and
granodiorite whose chief minerals are biotite,
epidote and magnetite. Marble and talc are also
found here.
Fossils: The most common fossils are fishes, plant
remains and footprints.

Most of the rocks of the Blue Ridge, which are of
earlier Precambrian age formed more than a billion
years ago. For the past 100 million years, erosion has
carved away much of Georgia's mountains, leaving
only their cores standing. Erosion continues today and
is constantly altering the landscape of the Blue Ridge
Mountains.
