1.Skarns or tactites are hard, coarse-grained metamorphic rocks that form by a process called metasomatism. Skarns tend to be rich in calcium-magnesium-iron-manganese-aluminium silicate minerals, which are also referred to as calc-silicate minerals. when any igneous body basically granite intrudes carbonate rock this type skarn due to metasomatism happens. and a big contact aureole will surrounded by limestone contact. The major dominant economic metals that make up skarn deposits are copper, tungsten, iron, tin, molybdenum, zinc-lead, and gold. so as for question Au,Sn,W will be associated with it. 2.if dolerite is intrudes into limestone then the contact aureole will be smaller as it is first cooling. Almost same type minerals are found also here.
