The Best Places for Detecting Metals and Gold
Detecting Metals and Gold , Many people seek to search for gold, which is the most important metal that is searched around the world, as it is a hobby for some and a profession for others. Gold is one of the most famous metals and a desire to own by people, whether for the purpose of trading, and the reason for this is due to the stability of its price in the global markets when buying and selling. Gold is still considered the most stable and widely used monetary base at the International Monetary Fund and the Bank for International Settlements. Gold is also widely used in making precious women’s jewelry due to its high value and its striking yellow color. It was also used by ancient civilizations in making jewelry for kings, the most famous of which is the mask of the pharaoh Tutankhamun, which is a masterpiece made of pure gold.
They are solid compounds that arise as a result of geological processes, and are studied within a specialized science known as mineralogy. Because of the importance of minerals, it was classified as the third kingdom in the natural world next to animals and plants, as Carolus Linnaeus classified it in this way. Metals differ among themselves in terms of color, transparency, and luster, and this affects their material and moral value to humans, and in view of this, the person strives to reveal the whereabouts of the precious ones; Such as gold, for example, or to protect itself by detecting the presence of weapons or mines that damage it and to get rid of them before it is too late.
Minerals in Nature
We know where the minerals are and how they originated. The question now is: does it exist alone or does it exist in mixed groups? Are these groups cohesive with each other or loose? What is the resulting form of these groups and natural mixtures?
In order to answer these questions, it is necessary to get acquainted with some scientific terms related to minerals, namely: minerals, mineral ores, mineral deposits.
Minerals are all materials extracted from the earth’s interior and consist of homogeneous chemical compounds, most of which were formed as a result of the fusion of natural elements.
As for mineral ores, they are: largely homogeneous materials consisting of metal components that can be extracted from ores by purification or smelting according to the nature of the ores. From this definition we note that mineral ores refer to metallic minerals such as iron and copper without non-metallic minerals such as sulfur and phosphate.
Mineral deposits are defined as: parts of the earth’s crust that contain one or more minerals that can be exploited on an economic level due to the quality of their properties and their availability in quantities that enable them to be exploited on a large scale. Man has been able to discover a large number of minerals exceeding two thousand, and these minerals constitute the various elements that make up the earth’s crust.
There are different forms in which minerals are found in the earth’s crust by metal detectors, according to the geological conditions during which they were formed. These forms can be identified as The mineral may be found in the form of veins permeating the rocks, in the areas where its minerals were concentrated at a later time to form the rocks.
Minerals concentrated in the rock formation
The minerals in this case are part of the rocks, as they were within the magma before it cooled or solidified, so they formed independent parts of the rocks even though it was inside them. It occurs when some mineral elements mix with an alkaline or acidic formation in the rocks. Examples include diamond, platinum and nickel, which are minerals found in alkaline rocks, in addition to tungsten and tin, which are minerals found in acidic rocks.
Some minerals are concentrated in the form of horizontal layers rather than in the form of veins. Some of these mineral layers may be formed by direct deposition of mineral elements in the bottoms of water bodies, whether lakes or seas, such as some iron ores. Others may form from these mineral layers as a result of the precipitation factor by evaporation from shallow water bodies, as is the case for gypsum ores and potash salts.
Do the Research
Research is the best way to find the places where gold occurs. You aren’t likely to find a brand new gold discovery, but what you are likely to find is an area within an existing gold rich area that still has some gold.
Find the old mines, rivers, and creeks where the early miners were searching and you are much more likely to have success.
Finding these places can take some experience. Some indicators are more obvious and others are somewhat subtle. An open mine audit is obvious, but a small creek that was hand-placered over 150 years ago might not be so noticeable. Finding historic mining sites is often dismissed by the beginners, but I assure you that experienced gold miners understand the importance of locating these places.
Geology and Contact Zones
You need to learn the geology of your particular mining area. There are some natural gold indicators that can be found in most major gold producing areas, but each area can be different. You should learn to spot the types of rock that are associated with gold in your area.
Gold is difficult to find, but learning about the types of rock that it is generally associated with (as well as the types that it is not associated with) will help you find the best areas to focus your efforts.
Contact zones (also called a dykes or intrusion) are places where two major rock types come together. This is a natural geological process that happened millions of years ago. These events would result in rapid heating and cooling, and this often created the conditions needed for gold to form.
Learning to identify the zones can be difficult, but it is something that will become more apparent as you learn to look for it. There are certain rock types that are better from a gold mining perspective.
3 important rock types worth noting are granite, schist, and gneiss. I have found these 3 types of rock to be present in most of the places where I have found gold.
When these geological masses would contact each other, pressure and high temperatures would cause fissures that would result in gold formation. Gold would be pushed to the surface, making it accessible to prospectors without needing to tunnel deep into the ground.
Identifying the general direction of the geology in your mining area is important. In most of the western U.S., the mountains range in a general northwest-southeast trend. Look for contact areas where some other rock type enters at a different trend to the general geological mass. Many of the richest gold bearing areas will have a intrusions that are at a 90 degree trend to the prevailing geology.
While granite, schist, and gneiss are usually the main rock types, that isn’t always the case. It can potentially be any combination of rocks, although they usually make up at least one of them at gold-rich contact zones.
The color changes of soil are also good indicators of a contact point. Sometimes the major source of bedrock has eroded away long ago leaving behind only soil. You may spot a band of reddish soil, indicating an iron rich intrusion that once existed. The host rock has eroded away, but the red soil (and potentially gold) still remains.
The ground changes can be obvious or subtle depending on their size or the difference in color. Ground cover from grass and trees can also hide them. Sometimes the type of plants growing in the different soil types can help you find them.
Contact zones can be as short as a few feet in length, or they can run for miles and miles, you can look at a map and see major gold mines that seem to line up perfectly in a straight line over miles and miles. They have located contact zones with gold.
Learn to Identify Natural Gold Indicators
I think that finding historic gold mining areas is the most important first step toward finding gold prospecting areas, but serious gold miners learn how to identify natural gold indicators. These are things that are commonly associated with gold.
While most of the rich gold mining areas have been found, there are certainly still some places out there with good gold that were completely overlooked by others. If you are fortunate enough to find one of these places, you are likely to be rewarded with some exceptional amounts of gold.
Once again, the main takeaway here should be that you need to learn you’re the geology of your mining district. When you understand the geology of the places where gold has already been found, you are more likely to spot the places where it might occur.
Often, the old geological reports that you use to research areas to prospect will tell you about the prevailing rock types found at a particular mine. Pay attention to those details.
Just as importantly, you need to know the rock types that are unlikely to be associated with gold. Don’t waste time looking in areas with a low chance of having gold.
Learn to Identify Man Made Evidence of Mining
Evidence of mining activity is most easily seen by finding the disturbances that the early miners left behind. Trust me when I tell you that an area is never truly “mined out.” Even places that once had thousands of men searching for gold will still produce gold today. They simply did not find it all. When the gold started to get depleted, the miners would move on. They didn’t get every last piece.
Plus, modern technology like metal detectors can recover gold that was missed by the old timers. Modern sluice boxes will capture gold that was lost by the crude methods employed by these early miners. We will discuss some of the specific indicators and how to identify them in further in this article.
