In geology, orogeny often means extremely strong geological movements, and the areas with the strongest orogenic movements are undoubtedly those areas where mountains are formed, generally speaking, the higher and larger the height of the mountain formation, the stronger the geological movement in the area, and the higher the pressure and temperature in the rock formations.

Just like the Nanga Parbat Peak, which is made up of five snowy peaks in front of you, the main peak is 8,126 meters high, and two other snowy peaks are also more than 8,000 meters high. What does this mean? Quite simply, this means that the rock formations in this area were the most intense during the orogeny movement that year, otherwise the rock formations would not have been forced out of three peaks of more than 8,000 meters!

And in this extremely intense rock activity, there are often some extremely valuable mineral deposits, such as a high probability of diamond mines, or the sapphire mine in front of you that is covered by a rock layer up to 4,000 meters thick!

Tang Feng excused himself a little tired, and went directly into the tent that had just been set up, and then couldn't wait to use the star core to conduct the most careful survey of this ore vein.

The intermittent sapphire mine that made Tang Feng scratch his ears and cheeks in the past two days, after coming to the main peak of Nanga Parbat Peak, really did not disappoint Tang Feng. Under the thick rock layer, dozens of sapphire deposits are concentrated together, forming this vein with a thickness of more than ten meters and an area of nearly two square kilometers.

The area of this vein alone made Tang Feng ecstatic, you know, the general sapphire vein is not so big, a few hundred meters long and ten meters thick vein is already a big vein, and here is actually connected by dozens of large sapphire deposits, forming such a large sapphire vein, which is almost unheard of.

But the facts in front of him made Tang Feng have to believe that this was indeed a rare super sapphire vein in the world, and the most important thing was. After careful analysis of the sapphire ore in this vein through the star core, the gem-quality sapphire content in this huge super sapphire vein can reach 40%, which is what surprised Tang Feng the most.

It is important to know that sapphire deposits and jadeite deposits are almost the same, and they are divided into primary deposits and secondary deposits. Primary deposits are also known as primary corundum deposits, and the general corundum content is between 20% and 80%. But among them, only about 10% of corundum can reach gem quality.

The secondary deposits of corundum, also known as the residual alluvial corundum deposits, tend to be the deposits with the highest yield of gem-quality corundum. This kind of secondary deposit separates the corundum in the basalt due to weathering, and is enriched by residual deposits, slope deposits and alluvial deposits. The particle size of blue and green corundum can reach 3~10 mm, and it is dispersed in the sandy clay layer. Among them, gem-quality corundum can usually account for about 35% of the entire deposit's output!

Star sapphire, for example, from Sri Lanka is a gem-quality sapphire from secondary deposits. The royal sapphire and pigeon's blood ruby of Mogok are also from secondary veins. Even the mine that produced Kashmir sapphires is actually next to a river, and Kashmir sapphires are also in the category of secondary ore veins.

Of course, this does not mean that the primary deposit will not produce gem-quality corundum, but the production rate of gem-quality corundum produced by this primary deposit is very low.

However, this piece of corundum native ore vein located under the main body of Nanga Parbat Peak has a probability of more than forty percent of being able to produce gem-quality corundum, which is definitely a maddening number.

And what made Tang Feng grin the most was that. Of the forty percent of gem-quality corundum, the top-grade cornflower sapphire accounts for almost one-thousandth of it. As for the second-class star sapphire and royal blue sapphire, there are also about 0.5% of each!

Even Tang Feng found a small piece of pigeon's blood ruby in this huge vein, which occupies about the same proportion as cornflower sapphire!

What does this mean? Quite simply, if you dig up two thousand five hundred pieces of ore in this vein, you will find a cornflower sapphire and a pigeon's blood ruby in it. You'll also find at least five Star Sapphires and five Royal Sapphires!

That's a remarkable number, because in Mogok in Myanmar or Sri Lanka, you might dig up tens of thousands of corundum gemstones, and you won't necessarily find a star sapphire or pigeon's blood ruby, but in this vein. This superb ruby sapphire can be found everywhere like a street shop!

This huge vein is really wonderful, the factor of ruby formation is because chromium ions penetrate into corundum, which forms ruby, and corundum without chromium ion penetration is sapphire. Traditionally, it is difficult for ruby primary ore and sapphire primary ore to appear together. The reason why the red sapphire produced in Mogok in Myanmar is because the corundum vein of Mogu is a secondary vein, which is formed by the river transporting the primary vein to Mogu and then depositing it, but the primary ore of the red sapphire produced in Mogu is definitely not together.

But here, the ruby sapphire primary mine, which was originally like an incompatible fire and water, appeared together, which can only be explained by one reason - nature is so magical!

Perhaps it is only in this kind of intense orogeny, in the core area of this orogeny, that this strange phenomenon can occur. But the world is so big that there are no surprises, and who can tell the real reason for this? Just like this vein, who would have thought that there would be such a world-class corundum vein in the rock formation four thousand meters below the ninth highest peak in the world?

Anyway, let Tang Feng explain this situation, Tang Feng just made an impromptu sigh - ah, nature, your sister is amazing!

But it's not magical, what is the reason for this phenomenon, Tang Feng is flawless to pay attention to! Now Tang Feng is thinking about how to incorporate this super corundum vein into the star core space, and then carry it to the designated area for placement.

It is no exaggeration to say that this huge vein is better than any red sapphire vein in the world, once Tang Feng can successfully transport this vein out, then Tang Feng's jewelry company will definitely not worry about red sapphire in the next few decades!

This is definitely the best gift given to Tang Feng by nature, and it is not in vain for Tang Feng to sleep in the open in the past few days.

In exchange for such a super vein with the hard work of the past few days, it is extremely cost-effective! (To be continued......)
