Gold also occurs sparingly in similar veins in granite and gneiss. It also occurs in the midst of rock formations without any obvious connection with quartz veins. Among such rocks are granite, aplite, gneiss, eurite, quartz-trachyte, syenite, andesite, basalt, diorite, gabbro, diabase, schists, porphyry and slate.

Determining the specimen's density is one of the first steps in recovering gold from gold ore. Knowing the density of the ore makes the process more effective. The density of gold ore varies from one type to the next. Typically, impure gold is around 16 to 18 times heavier than its associated host rock, which has a density of 2.5.

Granite is a very common stone, and not all of it contains gold. Examining granite for gold deposits is still a great method for prospectors. You'll generally be looking into cracks and crevices for accumulated gold, but there's another tell-tale sign. Most granite that contains gold also contains an appreciable amount of iron and quartz.
