Argillic As An Indication Of Mineralization

In the world of gold exploration martial arts, and especially in epithermal gold, one of the characteristics of the existence of these precious metals is the appearance of argillic rocks. Argillic as an indication of mineralization in an area of mineral resources, especially gold, silver and their accompanying minerals.

In addition, this rock unit shows the existence of a natural process, namely hydrothermal that occurs in rock walls that are breached or traversed by hot liquids carrying many naturally-produced economic minerals in the bowels of the earth not far from the surface.

In epithermal gold trap systems generally near the earth's surface and can be either high sulfide or low sulfide.
High sulphide epithermal gold deposits generally have a relatively low to moderate gold content of about 1 coma gram per tonne, but will be in large tons. Furthermore the gold processing will just quite easy, the Heapleaching process can applied to the ore material of the HSE resources gold.

Meanwhile, low sulphidation epithermal gold deposits will be able to have a large enough gold content so that they are sought after as a resource. Although the tonnage of the amount of resources is not large, those with high gold content will have large gold resources as well.

The difficulty gold processing will need more cost and technique so that amount of resources number should feasible for these ore material. It's need the crushing, grinding and milling before stripping the gold content in the ore.

Back to Argillic

Argillic is actually a clay mineral that varies from one called Kaolinite, Smectite, Illite, dickite and alunite. The last two are often referred to as advance argillic in the world of gold exploration martial arts.

Especially in the gold resource environment in the HSE trap system, you will find rock types such as Advance argillic and even low levels of kaolinite argillic.

Why are the explorers so favorite of this argillic rock?
Let's find out about the formation of this mineral, if we look at the genesis of this mineral, it is a mineral alteration caused by the presence of hot liquids in the porous space and causing mineral decomposition, for example, feldspar minerals were formerly converted into argillic minerals which include clay minerals.

His favorite mineral is argillic as a sign of mineralization that brings gold trapped in the rock formations. Now that's the most important thing in exploration after meeting with argillic, especially advance argillic.

The visible sign of this mineral is like chalk, which is very finely powdered and composed of the mineral glass silica. At the same time, it shows the presence of a high enough heat during the formation of the rock.

So it is expected that physically visible, the area at the location of the point contains gold, etc.

However, it is the chemist's laboratory that will determine the truth of the theory of this field.

While understanding the rock as the exploration progresses, it is best to immediately go to the laboratory to determine if the geochemistry is contained in the sample taken.

So so that you can immediately think about your further exploration steps and where do you want to go, just there or shift in which direction? North, East, South or West.

Volcanic Rock Tufa

Continuing the discovery of argillic rocks above, which generally will also be associated with volcanic rocks of the tuff type. Therefore, these tuff rocks are often deepened as Lapilli Tuff, Crystalline Tuff, and Lithic Tuff, although in general all of them are water-permeable shaft rocks.

In this type of volcanic rock, it has a perforated physical property which allows the passage of hot liquids to penetrate the interior of the entire rock formation without any bulkheads and is cut off by an impermeable layer.

That is so that resulting in a trap that is large in nature may form a Dome as part of the entire hill to the top.

I pay attention to all one another and a natural causal relationship.
This is the power of the Creator.

In the two images shown, it can be seen that the porosity of the rock is very clear, which allows for fluid infilltrate to bring about changes in mineral decomposition. While solid rock is certainly not a space that allows the entry of hot fluid carrying mineralization as above.
