“Soils Associated with Gold Deposits”
🔶By far, the best-known type of soil which may indicate the presence of gold is known as “black sand.”
Let’s know more about it
🔶 Black sands are certainly not proof of the existence of nearby gold, only that the soil has a lot of minerals and heavy metals, one of which is gold.
🔶 Gold is one of the heaviest substances – about 19 times the weight of water – so any gold being carried by water in a stream is the first to fall.
🔶Black sand is not as heavy as gold, which is more than 3 times as heavy as the iron which makes up much of the black sand, it still weighs more than most other substances. So, while black sand does not guarantee gold, it is definitely worth a look for that elusive treasure.
🔶Changes in the color of soil can be another indicator of nearby gold. Iron staining is another excellent indicator that gold may be present.
🔶The iron stains are in yellow or reddish soil.
🔶Soil which contains iron may also be black, provided it has not oxidized.
Where iron or other heavy metals are located, gold may also be found.
🔶Soil and rocks are sometimes bleached to a lighter color than other nearby rocks due to acid from lode deposits underground.
🔶Sometimes, gold is near that lighter rock and soil.
🔶Contact points between different types of rocks can be another sign that gold may be nearby.
🔶 This very important indicator is often overlooked by prospectors.
🔶 Contact points are usually where different rock types come together at a 90-degree angle.
🔶 The existence of contact between different rock types is often more important the rocks themselves.
🔶When different types of rocks came into contact deep underground, the resulting pressure and very high temperatures due to this pressure caused fissures to develop in the rocks.
🔶 Gold would liquify under this heat and be pushed up toward the surface. Over time, the gold cooled and returned to its solid form.
🔶Thanks to this pressure, gold will now be close enough to the surface for even amateur prospectors to find
🔶Contact points where different types of rocks meet can also sometimes contain stones that are damaged so they crumble easily.
🔶There could be gold in those crumbly rocks. The border between the rock types on the surface could be the key to what lies beneath the surface.
🔶Although gold might be found in many different types of rock, quartz may be the most likely home for gold. Just saying “look for quartz” would be much worse than a waste of time, because it is the second most common substance on the planet.
🔶Although most types of quartz might potentially contain gold, rocks known as “dirty” or “rotten” quartz are much more likely have gold.
🔶Ironically, these rocks might be considered to be the least attractive when looking them.
🔶However, the brown or orange pieces contained in the dirty quartz are oxidized iron pyrite, which is commonly found with gold.
🔶 Perhaps this is the perfect example of not judging a book by its cover – what looks ugly on the surface may be a sign of something truly beautiful underneath.
