Xie Dafei took a shovel and drew lines one by one on the inner wall of the exploration side.

From the top of the modern cultivated soil layer, to modern times, to the Song Dynasty, the Shang and Zhou dynasties.

Soon, the upper layer of about fifty or sixty centimeters of soil was divided into four cultural layers.

These four cultural layers, if you look at it with the naked eye, in fact, the soil layer is not obvious, although there is a little difference in soil color, but if you want to accurately distinguish, it is still very rare.

Only an expert like Xie Dafei, who has focused on field archaeology for more than ten years, can be so golden.

However, when the cultural layer was divided into the lower layer, even Xie Dafei was a little hesitant.

Further down, it has entered the cultural layer of Sanxingdui.

And it is difficult to stratify the Sanxingdui cultural layer.

From the naked eye, the soil color of the underlying soil layer is almost the same, and it is difficult to distinguish it by the soil color alone.

But obviously, Sanxingdui, as a civilization spanning two thousand years, cannot be divided into cultural layers.

Now at the bottom of the excavation, pottery shards and stone tools have been unearthed, indicating that it should be around the late Neolithic period, that is, the earliest origin of Sanxingdui culture.

In the middle, there are also three phases of bronze culture, and the top layer is the late Shang culture layer.

"This has already reached the Sanxingdui period, that is, the stages below the Sanxingdui period, which is not very clear." Deng Xin said sincerely.

Although she studied botanical archaeology, it is not impossible to stratify the cultural stratification.

She can also distinguish the above cultural layers, but after entering the Sanxingdui period below, it is really a little too complicated.

"Let's scratch it first." Xie Dafei also nodded solemnly, not as casual as before.

He took a shovel and scraped it on the wall of the pit.

The meaning of this is very simple, that is, hang up the outer layer of soil that has been air-dried, and look at the soil color of the inner layer.

The freshly exposed layer of soil is the best to identify.

It's just that when the surface layer of soil is scraped off, stand up and see, in fact, it is still difficult to distinguish the Sanxingdui cultural layer.

At least, Chen Han and Deng Xin really can't see the difference.

"I can't see the difference."

"Is it possible that this is the same level? It's just that different things are poured, so different things are formed, and it's more difficult to distinguish. ”

Deng Xin and Chen Han were both discussing.

However, Xie Dafei did not think so.

It may be difficult for others to distinguish this cultural layer, and the construction site cannot be excavated.

But Xie Dafei can.

The entire Sanxingdui ruins are circulating a sentence, if you want to distinguish the layers clearly, it is right to find Xie Dafei.

As long as he touches it, he can immediately tell which issue is which!

The soil, which is similar in everyone's eyes, is rough and delicate in Xie Dafei's hands.

Even if the color is the same, you can also feel the difference in soil layers in different ages when you touch it.

It's a one-handed trick!

Now, Xie Dafei is using this unique skill.

He stretched out his hand and stroked the freshly scraped soil layer, touched it up and down, and knew it in his heart, and began to draw lines on the soil layer with a hand shovel.

Phase I, Phase II, Phase III, and Phase IV currently being excavated at the bottom of the pit.

He divided all the layers of soil.

"Awesome, Senior Brother Xie!"

"It's got to be Da Feige."

Chen Han and Deng Xin both gave a thumbs up.

Let's not talk about whether this cultural layer is divided or not.

At least if you can tell it, it's already awesome.

Let Chen Han and Deng Xin come, they will only be helpless with a hand shovel, and there is no way to draw a line.

"Okay, let's divide the cultural layer like this first, what other difficulties are there on the construction site?" Xie Dafei smiled a little smugly.

Deng Xin hurriedly pulled him, got on the exploration side, and walked to a place next to him where a lot of pottery fragments were piled up.

"Brother, help me see if these pottery pieces are the same artifact, I'm a botanical archaeologist, and I don't know much about pottery."

Chen Han hurriedly followed.

Helping young archaeologists solve various incurable diseases on the construction site is one of Xie Dafei's main tasks.

Carrying a few small horses, sitting in front of a pile of pottery shards that had just been dug out and still had soil, Xie Dafei fiddled with these pottery shards at will.

"Hey, garbage classification, start from the ancient Shu people."

"Xiao Deng, you said before that the detectives you are responsible for may be the garbage dump of the ancient Shu people, I think this guess may be right."

"The broken and broken pottery is estimated to be thrown here in the first and second phases of Sanxingdui."

Just by sweeping it, Xie Dafei could see that these pottery shards obviously did not belong to one pottery, but to the fragments of multiple pottery.

Chen Han is also very professional in this point, and if he roughly identifies it, he can see the fragments of jars, urns, and basins.

And none of them are complete, and they don't seem to be able to form a complete pottery with each other.

Maybe the debris hasn't been completely cleaned up, or maybe it's just a pile of incomplete debris that was buried here.

It's no wonder that Deng Xin complained before, feeling that he was digging a garbage dump.

It's just that these things were garbage in the era when the ancient Shu people lived, but now they are precious cultural relics.

After sorting out these pottery pieces, Xie Dafei said with satisfaction: "This party can almost be settled, you can collect the map and data, and you can let the workers backfill it." ”

The job of digging and exploring the party is not really endless digging down.

Generally, after a cultural layer is cleared, you can map and collect data to settle the square, and you can dig another exploration method again in the next year's excavation season.

What is particular about is a covering excavation, digging dozens of square meters a year, sooner or later all the contemporaneous cultural layers in the Sanxingdui site area can be dug up, and the source and composition of Sanxingdui culture can be figured out.

Of course, Deng Xin's construction site is not only such a probe.

And the depth of each probe is also different.

With his hands behind his back, Xie Dafei continued to take the two of them around the construction site.

Soon, a shallower probe caught his attention.

The depth of this probe is only twenty or thirty centimeters.

However, on the low soil layer, there are several long ruins drawn by hand shovels.

"You can focus on digging this pit next!"

Standing in front of the pit, Xie Dafei said in surprise: "This is a ship coffin!" ”

"But the wood has completely decayed, and it has fused with the earth, leaving only these long strips."

Deng Xin nodded in agreement.

The so-called boat coffin burial, as the name suggests, is to use some relatively thick wood, dig a long gap in the middle, and use it as a "boat" to bury the deceased.

This is a burial custom of ancient tribes in southern China.

Because the ship-shaped coffin is used as a burial tool, it is called a boat coffin burial.

This kind of burial custom is divided into two types: open burial and earth burial, which was popular from the Shang and Zhou dynasties to the Western Han Dynasty.

Obviously, what was found on the Moon Bay side was the type of burial.
