A metal that occurs in vast limestone deposits and combines with oxygen to form an oxide with a formula MO.
Any sources?

There is no such element as M. Maybe your teacher meant M to mean "some metal".
The metal referred to is calcium which forms CaO, calcium oxide, also known as quicklime.

Calcium Oxide.

the metal M is Calcium (Ca) and the oxide is CaO (calcium oxide). Ca occurs in nature in the limestone deposits and the marble. limestone/marble is essentially, CaCO3 (calcium carbonate)

ok you're teacher was using M=metal. limestone is calcium carbonate so M=Ca. Don't be so literal and science will make more sense. M is a common abbreviate for metal in organometallic (etc.) chemistry where multiple metals are possible to make a reaction work

Yes, the "M" in "MO" refers to the metal in question which is Calcium, chemical symbol "Ca", while calcium oxide has the formula "CaO". In limestone Calcium exists as Calcium Carbonate, "CaCO3".

M is the metal which has to be identified that 's obviously calcium

Your teacher most probably meant, Mg (s-element) or Mn(d-element), or Mo (d-element). It may be MgO... Check out wikipedia for info of these elements.
