gold
In nature, many compounds, such as tellurium, calcite and quartz, contain gold. Gold also can occur freely in nature. It is a malleable, shiny and soft metal that has the chemical symbol Au. Malleable means that it is easy to hammer or beat gold into thin sheets or thin wire.Some other physical properties of gold are that it is a conductor of electricity and heat, and it has a melting point of 1064.18 degrees Celsius. It also has good reflectivity properties.Presently, gold has many uses, including for jewelry, electrical contacts, printed circuits, shielding on space vehicles and dental alloys.
 marble
It is none of both: it is a compound or at least a material (stone), not an element indeed.
Marble is a stone. Marble is a metamorphic rock composed of recrystallized carbonate minerals

petroleum

Petroleum is not a mineral, it can contain mineral particles such as sand, and sand often contains Quartz which is a mineral.
