Hi, welcome to MI Enviro-Minute.
I'm Jason Stilger.
All of these rocks are from Michigan, including
one of my favorites: the petoskey stone.
What is really cool about Michigan is that
it is made up of all three rock types: Sedimentary,
Igneous, and Metamorphic.
Let's learn more - Start the clock.
The Michigan basin is made entirely up of
the lower peninsula and the eastern part of
the upper peninsula.
This is where you will find sedimentary rocks
like limestone, shale, and sandstone layered
on top of eachother like a stack of saucers.
Under these "saucers" of sedimentary rock,
you can find igneous and metamorphic---which
you can also find at the surface of the western
UP.
Not only is Michigan's geology fascinating,
but it is also important to our economy.
The igneous and metamorphic rocks of the upper
peninsula contain valuable minerals, such
as iron ore, copper, gold, zinc, and nickle.
Meanwhile, sedimentary rocks can contain petroleum,
natural gas, salts, gypsum, and lime stone.
As Geologists of the Oil, Gas, and Minerals
division, we ensure responsible development
of Michigan's mineral resources while protecting
the environment, property rights, public health
and safety.
