DOLOMITE:
Dolomite or Magnesian limestone, consists mostly of the
mineral Dolomite.
Most Dolomites are
secondary rocks,
probably formed when water, containing magnesium, seeped
through layers of limestone,
replacing the calcite with dolomite. Recrystallization probably destroyed most of
the fossils.
The texture of Dolomite is very variable and the beds are
often thick and highly jointed.
This
white, cream or grey rock weathers to brown or pink.
