What Rocks To Look For When Gold Prospecting. It helps to know a bit about rocks when seeking gold. Granite, basalt, schists, slate, and shale are rocks to look for when gold prospecting. Large quantities of iron oxides such as magnetite, ironstone, or hematite in an area can also indicate the presence of gold. Rock 1 – Quartz Veins

However, the absolute gold mineralization age is not well constrained due to the lack of datable gold ore-related minerals. In this study, in situ monazite U–Pb and mica Rb-Sr dating were performed to constrain the mineralization timing. The Shenjiayao gold ores occur as massive auriferous pyrite veins in Precambrian metamorphic rocks.
