Many ores that contain gold contain other metallic metals in them also, so there are likely to be a lot of shiny minerals mixed into the rock which may or .
Igneous rocks such as granite or lava are tough, frozen melts with little texture or like these contain mostly black, white and/or gray minerals. Sedimentary rocks such as limestone or shale are hardened sediment with sandy or claylike layers (strata).They are usually brown to gray in color and may have fossils and water or wind marks.
Gold encased in quartz rock, also known as gold specimens, are highly sought after by collectors and prospectors. They can be hard to find, but using the proper equipment and tactics, it is possible to find beautiful specimens.
If it were to turn into an igneous rock then the rock would melt from all the heat below the earth and it would become magma. Then like all igneous rocks it would either explode from the volcano and dry on land, or it would stay below the earth and dry there, both ways it would become an igneous rock.
Sedimentary Geodes. Geodes in sedimentary rocks are usually found in limestones, dolomites, and calcareous these deposits a gasfilled void can serve as the opening for geode formation. Shells, tree branches, roots and other organic materials often decay away to leave a void for the formation of mineral materials.
