Gold deposits are found in a great variety of rocks; but, as might be expected from the close connection with igneous intrusions, the most favorable rocks are of the metamorphic kind, particularly mica schist, quartzite, and slate. Limestone is not as favorable; but some of the BC copper-gold deposits are in limestone. Where to Find Gold in Ontario
Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits.

Dolomite is formed when the calcium in limestone is gradually replaced by magnesium. Magnesium-bearing water filters through limestone and replaces about half of the calcium in limestone, turning it into calcium-magnesium carbonate (the mineral dolomite). This process, called dolomitization, is still poorly understood.
Some examples of sedimentary rocks include sandstone, shale, and limestone. 3. Igneous Rocks. ... one of the easiest ways to test whether or not you've found gold is to do a magnet test. Iron pyrite, commonly known as "fool's gold," is attracted to magnets, while real gold is not. So, if you hold a strong magnet up to your piece of ...

Dolomite is a mineral and a rock-forming mineral that is composed of calcium magnesium carbonate (CaMg(CO3)2). It is named after the French mineralogist Déodat Gratet de Dolomieu, who first described its properties in the late 18th century. Dolomite is often found in sedimentary rock formations and can occur in a variety of colors, ranging from white to gray, …

These are colorless agates that are found in limestone. So… after finally acknowledging that they do in fact exist, a new model was proposed for these do agates: they must have formed in cracks and cavities- hollow spaces- in the limestone and dolostone rocks and formed in pretty much the exact same way as the volcanic rock agates.
