The Secret History of Mars.

Chapter 274 Alternative Water Source

"What Yizhou said just now is right, this is indeed not the calcium carbonate on the earth!" Elder Cangxi casually stroked the inner wall of the bee's eye, "But what Xingmeng said makes sense, this can also be regarded as a stalactite!"

Elder Cang Xi’s words confused Cui Xingmeng and Yuan Yizhou, it’s not calcium carbonate, but it’s a stalactite, what does it mean? !

Seeing that Elder Cang Xi could touch the inner wall of the bee hole, the curious Cui Xingmeng followed suit, and gently touched it with his right index finger.

It was hard at first, but soon, Cui Xingmeng's fingertips began to heat up. The feeling of being hot but not hot was quite comfortable.

Cui Xingmeng retracted her finger and took a closer look. Except that the fingertips were a little reddish, the skin seemed to be drier than other fingers!
"Elder Cangxi, there is no water source on Venus. Even if these landforms are not formed by calcium carbonate, how can they accumulate layers and be dissolved and precipitated?" Yuan Yizhou was also a little puzzled and asked.

"Who told you that there is no water source on Venus?" Elder Cang Xi said with a smile!
"You mean, there is water on Venus?! Under such high temperature and pressure?! Even the hydrogen molecules are blown clean by the solar wind. Where does the water come from?!" Yuan Yizhou was even more confused!

"Mr. Yizhou just asked the question outside the cave, did you find the answer?" Elder Cang Xi didn't directly answer Yuan Yizhou's question, but asked back!
The geological model of Venus he mentioned before is just the opposite of the earth!
The magma in the volcano is not pushed to the surface by the energy in the core mantle, but is extracted from the core mantle by the high temperature and pressure on the surface!

"Well, I saw the crater. The magma that flows out is dark red at a relatively low temperature. After it flows out, it is heated to a more fluid scarlet color and spreads everywhere!" Yuan Yizhou collected and sorted out the magma in his brain. The evidence you see proves your model.

Elder Cang Xi was noncommittal and asked, "What else?"

"The Arctic hole in the mantle of Venus is indeed low-temperature and low-pressure. I haven't seen any liquid magma. Most of the magma here is solid!" Yuan Yizhou continued, as if trying to convince himself, but he always felt that Something is wrong!
"Mr. Yizhou, what insights do you have about the composition of these magma?!" Elder Cang Xi smiled slightly, neither agreeing nor objecting to Yuan Yizhou's inference.

"The composition of these magmas?!" Yuan Yizhou didn't think about it from this angle, "Just outside the cave, you said that it's basalt!"

"Basalt is a very broad concept! In a broad sense, we call all the materials that pass through the crater and come from the ground to the surface!"

Elder Kuraki explained, "For example, the magma in Mount Olympus on Mars was once basalt rich in iron, so it can be used by me to refine soil!
On the other hand, when volcanoes erupt on the earth, they are composed of silicon oxides, which cannot be used to refine soil! "

Elder Cang Xi followed the lead, "The melting point of basalt mainly composed of silicon oxide is between 1000C and 1200C, which cannot meet your assumptions. The geological model of Venus!"

Yuan Yizhou suddenly realized, isn’t it? The surface temperature of Venus is 450C to 500C all year round. If the volcanic magma of Venus is also basalt mainly silicon oxide, let alone the surface cannot be pumped out, even if it is pumped out, it will not be melted!
"Let's take a guess, what is the main composition of the basalt on Venus?"

Seeing Yuan Yizhou, Elder Cang Xi had already heard his own model and the most critical conditions for his establishment, so he continued to guide and ask questions!

"The surface of Venus, in addition to high temperature and high pressure, is also high in sulfuric acid..." Yuan Yizhou muttered to himself, "Could it be that the crust of Venus is mainly composed of sulfates?!"

Elder Cang Xi listened, and nodded lovingly, agreeing to Yuan Yizhou's conjecture!

"Since it is sulfate, its melting point can be melted at around 450C, but it can remain solid in the mantle!" Encouraged, Yuan Yizhou raised his hand to touch the inner wall of the bee's eye, and continued to infer!
Yuan Yizhou's palm touched the inner wall for a while, and suddenly, he retracted his palm like an electric shock!
Cui Xing dreamed about it, and hurriedly stepped forward to check, "What's the matter, did you get burned? It wasn't so hot when I touched it just now!"

At the same time, feeling distressed, he cupped Yuan Yizhou's hand with both hands, and said, blowing lightly.

"I'm fine, I'm not hot!" Yuan Yizhou comforted his lover and said, "I think, I know the main ingredient of the basalt on Venus!"

Yuan Yizhou turned to face Elder Cang Xi, and said with piercing eyes. "It's magnesium sulfate!" Yuan Yizhou said with certainty.

"Let's hear it!" Elder Cang Xi didn't admit it, nor denied it, but waved his hand, signaling them to follow him to the inside of the bee hole!

After walking a few steps, Yuan Yizhou and Cui Xingmeng could clearly feel the coolness and refreshingness in the cave!

It is completely two seasons with the bee eye cavity where it was just now!
Cui Xingmeng secretly used his fingers to scratch the inner wall of the bee hole next to the aisle. Sure enough, the wall here is not only not dry and hot, but also feels damp and cold!

Cui Xingmeng was in a trance, and had the illusion of being in a stalactite cave on the earth again!

Yuan Yizhou also felt the moisture on the inner wall of the bee hole, and then looked up again. The internal structure of the bee hole was "ridden with holes". He was not in a hurry to answer Elder Cang Xi, but fell into deep thought!
Elder Cang Xi didn't urge him, and continued to lead the way, leading Cui Xingmeng and Yuan Yizhou to the depths of the bee hole!

After walking for a while, Yuan Yizhou broke the silence and said modestly, "Elder Cang Xi, I have a theory, please correct me!"

Elder Cang Xi looked back at Yuan Yizhou, without stopping, and said, "Please tell me!"

"This is the water source of Venus!" Yuan Yizhou boldly expressed his thoughts!

Cui Xingmeng was startled, and touched the inner wall of the bee hole with her hand. At this time, the wall was even colder than before!

Gently rubbing the surface, Cui Xingmeng's palm was actually stained with liquid.

Cui Xingmeng took the palm of his hand and looked at it carefully under the dim light in the cave. It was clear and transparent, colorless and odorless, it really looked like water!

"Yes, what else is in your theory?" Elder Cang Xi admitted without hesitation.

"These stalactites are the raw materials for resurfacing the crust of Venus that you just mentioned before entering the cave! That is, the basalt that will be pumped from the crater to the ground!"

Yuan Yizhou continued to explain his thoughts.

"It's the magnesium sulfate you mentioned just now?" Cui Xingmeng had been paying attention to the conversation between Yuan Yizhou and Elder Cang Xi, so he interjected to clarify his understanding.

"These are not just magnesium sulfate, because the melting point of magnesium sulfate is similar to that of the basalt on the earth, which is mainly composed of silicon-oxygen compounds, and it is also more than 1000 degrees!"

Yuan Yizhou shook his head and said, "This is an alternative water source on Mars. The water is in the form of hydrate and exists in magnesium sulfate heptahydrate!"

After hearing this, Elder Cang Xi paused and stopped!
