What important mineral deposits were formed during the cariboniferous (pennsylvanian)period?

Answer 1

The Pennsylvanian Period is considered to be late carboniferious. The name comes from the massive bituminous coal deposits that are found throughout the state of Pennsylvania. Carboniferous derives it name from carbon.

It can be said that during this time most of the world's coal deposits were laid down, the coal being formed from compressed layers of rotting vegetation.

Answer 2

Coal is of course the most important and well known deposit of the Pennsylvanian Period, but several other deposits from that time are important also. Clay associated with the same cycles responsible for coal are used in refractory bricks, structural bricks, and ceramics. The limestone deposits are generally not as important as those from some of the other periods, but they still provide dimensional stone, aggregate, and agricultural lime. Pennsylvanian sandstones sometimes are of sufficient quality to be used as building material.

The terms Upper and Lower Carboniferous are used in Europe while in America the Mississippian and Pennsylvanian are used for the same times.

Answer 3

I recall being told in my first year in geology (over thirty years ago)that the Carboniferous is, world-wide, the most economically important geological period, mainly due to coal, but also iron and aggregates. A bit hard to believe even in those days given the amount of oil in Mesozoic and younger rocks, but I merely repeat what I was told back then.

Answer 4

The Carboniferous Rocks are in 3 subdivisions.

1)The lower Cardoniferous (coal-bearing) consists of the Mountain Limestone (rich in corals).

2) Millstone grits

3) Coal

Answer 5

primarily, carboniferous refers to deposits of coal, hence the term CARBON in the name.

Various layers of strata formed at this time bear differing geological markers: limestone (in lower areas covered by seas in prehistoric eras), lime encrusted green algea, crinoids, etc.
