8. Age of Coal Deposits
Majority of the coal deposits are
Pennsylvanian (P) in age; no
coal deposits that are older than
the Devonian (D(.
Land plants had not fully evolved
prior to Devonian therefore coal
deposits which are the remains of
plants could not have formed.
It is also a time in geologic
history when major continental
glaciers occurred in the southern
continents.
Note: carboniferous is divided into
-Mississippians
-Pennsylvanian

9. Note : A maceral is a component, organic in origin, of coal or oil shale. The term
'maceral' in reference to coal is analogous to the use of the term 'mineral' in reference
to igneous or metamorphic rocks. Examples of macerals are inertinite, vitrinite and
liptinite.

10. Examples of Macerals

12. The higher the coal rank the
higher the temperature and
pressure of coal formation.
The higher coal ranks have
a higher percent carbon
and less water.
As moisture and volatiles
are driven off during coal
maturation, carbon is left
behind.
The increased carbon
content increases the heat
content (Btu/lb) of the coal.

1.1.“G.Maghara ", (Jurassic-
Bathonian), and its backup or
reserve is estimated at 52 million
tons.
2."Ayun Mousa“ subsurface coal
deposits that similar in age to
Maghara coal deposits and
backup is estimated at 40 million
tons.
3.Northeast the "Abu Zenimah",
estimated reserve of 75 million
tons.
