History of [𝐏𝐋𝐀𝐍𝐄𝐓-𝐍𝐎𝐓-𝐅𝐎𝐔𝐍𝐃-𝟒𝟎𝟒]

Prepræterian is a first geological supereon of [𝐏𝐋𝐀𝐍𝐄𝐓-𝐍𝐎𝐓-𝐅𝐎𝐔𝐍𝐃-𝟒𝟎𝟒] before the next geolgical eon including modern time. This eon has divided three eons.

Pikminoterra-Nativitan: The Birth (4817 ± 0.16 ~ 4281 ± 3 Ma)

(Shortly Pt-N) The solar system of [SNF-401] is dated to 4.85 billion years ago, the [PNF-404] was formed about 4.817 ± 0.16 billion years ago. While during that time, the proto-[PNF-404] was a planetesimal. During early, this planet is a hell with extremely hot temperature, volcanic activity, magma ocean, atmosphere that doesn't contains oxygen (o), hydride-rich instead, has gas giant that contains chemical composition such as water vapor, methane (CH₄) and ammonia (NH3) & doesn't have any life or organic matterial. 

Until One ancient planet that sized simillar to [PNF-405] suddenly crushed to proto-[PNF-404]. After that, the ancient one was no longer a planet, rather became into disc of derbis that formed into moon of [PNF-404]. Over time, the planet is no longer a hell, where the surface suddenly turned cooler. The atmospheric water vapor changed (condensed) into liquid water that covered the surface. The atmosphere got altered into new chemical compositions such as nitrogen (N₂) & carbon dioxide (CO₂) rich atmosphere instead of hydride and reduce. Also the crust & mantle was formed.

According to some research, possibly "the first children" of [𝐏𝐋𝐀𝐍𝐄𝐓-𝐍𝐎𝐓-𝐅𝐎𝐔𝐍𝐃-𝟒𝟎𝟒] has appeared during late stahe of this eon though through complex chemical process called Abiogenesis, however, it's still unsolved. The most-accepted suggestion is the first life was actually evolved from organic molecules (such as sugar, amino-acids & nucleic acids) from space that transform to [PNF-404] through astronomical objects such as asteroid, space dusts and whatever others, the least accepted suggestion is the first life is originated from hydrothermal vents through complex abiogenesis & similar to most-accepted suggestion but it's microbial alien ancestor instead. After "the first children" appeared, viruses may appeared first. After the virus, "the last children" of [𝐏𝐋𝐀𝐍𝐄𝐓-𝐍𝐎𝐓-𝐅𝐎𝐔𝐍𝐃-𝟒𝟎𝟒] possibly appeared around 4.55 or 3.75 billion years ago.

Today, somewhere in Neoaustra, there's a most oldest zircon crystal from this eon.

Archanizoic: The Beginning (4281 ± 3 ~ 2750 Ma)

After the events of "huge crash" & latest Pikminoterra-Nativitan (4.281 ± 3 Megaannus), the [𝐏𝐋𝐀𝐍𝐄𝐓-𝐍𝐎𝐓-𝐅𝐎𝐔𝐍𝐃-𝟒𝟎𝟒] suddenly changed. The skies, oceans and possible first life has appeared through mysterious abiogenesis event, later "the last children" appeared after "the first children" and virus, around 4.55 or 3.75 billion years ago. However, most research suggest that "the first children" appeared during this eon, around, 4.02 billion years ago. 

Unlike today, most part of this geological time is water world, which continent has appeared at late archanizoic. The heat flow was three times higher than today due to accretion, formation of metallic core & heat flow from radioactive elements that are decay. Also this geological eon has high volcanic activity, many eruptions also produce unique rocks such as komatiite and more. Some rocks such as carbonate rocks are rare than today, which we can know that the oceans are acidic than today. Typical stratum formations of archanizoic is green belts. Green Belts has unique sedimentary rocks such as metamorphic and metasedimentary rocks that contains rich-iron and magnesium and minerals such as chlorite, actinolite, amphiboles, gold, ore and more. Also green belts has their own unique felsic volcanic rocks.

The biota of Archanizoic is two domains, both Euprokaryotes and Archobionts. Both of these organisms are known as prokaryotes, a paraphyletic term of unicellular asexually reprductive (through fission) organisms that lacks mitochondria & membrane-bound organelles including nucleus. The best examples of archanizoic life remains are Stromatolites, a unique specialized microbialites by prokaryotes such as Microcyanophytota (Photosynthetic bacterias), Self-reducing bacteria and Proteokarydota. However, Microcyanophytes led Great Oxygen crisis event happened on both oceans and atmosphere, during 2.710 to 2.676 billion years ago.

Today, somewhere on both continents, Proxima & Neoaustra has rocks that are actually remains of Archanizoic such as Granites, Diorites, Layered intrusion that are either base or superbase, Anorthosite and Monozonites known as sanukitoids. These rocks usually formed on deep water sediments such as, Mud stones, Graywackes, Volcanic sediments and Banded iron formations. 

• Eoarchanian (4281 ± 3 ~ 3850 Ma)

Between latest Eoarchanian to earliest stage of this era, both 3750 million years ago, a small continent, Vaalbarterra has already formed until 2950 million years ago.

However, seems this era has restricted formations and lack of data. At least somewhere on Proxima & Neoaustra has geological formation of this era. This two formations has contains sedimentary rocks and fossilized euprokaryote and stromatolites.

According to Purple [PNF-404] Hypothesis, the surface biosphere of this era was purple since, Eoarchanian due to the early photosynthetic organism were actually based from retinaldehyde that are simple, instead of complex chlorophyll based on porphyrin.

• Mesoarchanian (3750 ~ 3050 Ma)

During this era, the plate subduction became into similar to plate subduction of modern [PNF-404]. Also the atmosphere has high amounts of methane (CH₄) and carbon dioxide (CO₂) and ocean temperature is obviously different to modern day, it is 55-85℃.

Around 3350 million years ago, some parts of Vaalbaterra has split. Which this split part formed into Ura, a second supercontinent that is taller than Vaalbaterra.Later at 3150 million years ago, the first and oldest glaciation event happened.

Prokaryotes expand their biological diversity including expanded metabolism and oxygen producing microcyanophytes. However, their oxygen didn't accumulate in [PNF-404] atmosphere until later. Also hypoxia oases with high amounts of oxygen existed.

• Neoarchanian (3050 ~ 2750 Ma)

Ferronian is a first period of Vetuproterzoic era, around 2750 million years until 2550 million years ago. 

There's many banded ironstone formations of early Ferronian. These unique iron formations are usually formed from seawater combined with oxygen wastes from oxygen-producing microcyanophytes, the dissolved irons from oceans formed into insoluble iron dioxide, then deposit in sea floor and formed in a varbe-like thin layer.

However during the beginning of the ferrocene, something has happaned...

The Great Oxygen crisis has happened. Due to free oxygen rises by microcyanophytes, both shallow marine waters and atmosphere. The oxygen combines with iron ions, dissolved ocean irons deposit and formed into iron dioxide, suddenly the whole ocean turn into blood. Also it led most of anaerobic biosphere went extinct. However, luckily some of them went survived on some habits that lacks of oxygen.

◦Prosperikaryan (2550 ~ 2300 Ma)

Prosperikaryan is a second period of Vetuproterzoic era, around 2550 to 2300 million years ago.

Where the major glaciation event from previous period continues until 2450 million uears ago. So the whole planet around 80% is major glaciation. This means the planet tempurature was -50℃.

The first Prosperikaryote appeared during this period due to special endosymbiosis event between host cell Avuarchota and Paramitochondriales via phagocytosis process.

During 2450 million years ago, there's an unique macroscopic biota that looks flat, flower-shaped and don't have metamorphism. These organisms are probably planktonic and move through water column. Today, these organisms were can found on somewhere on northern Proxima. However, these organisms are controversial, some sugget that they're pseudofossils rather than actual organic remain.

◦Montaranian (2300 ~ 2050 Ma)

Montaranian is a third period of Veturproterzoic era, around 2300 to 2050 million years ago.

Where the great oxygen crisis event ends and several big asteroid impact happaned at that period. Later at 2070 million years ago, a new supercontinent has formed. Also many mountain ranges happaned.

◦Stabilian: Boring. (2050 ~ 1850 Ma)

Stabilian is a last period of Veturproterzoic era, around 2050 to 1850 million years ago.

Between latest Montaranian and start of this period, around 2050 million years ago, The Boring Billion event has started. Where the climate changes, tectonic shift, oxygen level and evolution was slower than before. Even there's no mass extinction event at all.

The ocean was sulfidic and has purple or black milky turquoise coloration due to poor nutrient & oxygen and purple photosynthetic euprokaryote that use sulfane and produce carbon.

• Mesoproterzoic (1850 ~ 1250 Ma)

Mesoproterzoic is a second era of Proterzoic eon around 1850 to 1250 million years ago. Where boring billion still continues.

◦Calymmimundan (1850 ~ 1650 Ma)

Calymmimundan is a first period of Mesoproterzpic era arpund 1850 to 1650 million years ago.

Geologically where the platform covers was expanded and cratonized basements formed a new platforms.

Also the first plant appeared at the beginning of that period, which red algae (the oldest plant member) appeared first.

◦Ectasiterran (1650 ~ 1450 Ma)

Ectasiterran is a second period of Mesoproterzoic era around 1650 to 1450 million years ago. It was named after platform cover expansion from previous period.

Time period was obviously dofferent to today, 17 hours 32 minutes at early, 18 hours 28 minutes at late.

The first sexual reproduction also appeared, especially on true-multicellular life on [𝐏𝐋𝐀𝐍𝐄𝐓-𝐍𝐎𝐓-𝐅𝐎𝐔𝐍𝐃-𝟒𝟎𝟒], these organisms has specialized haplpid cells, gamate.

◦Angustonian (1450 ~ 1250 Ma)

Angustonian is a last period of Mesoproterzoic era around 1450 to 1250 million years ago.

Where narrow metamorphic rock belts was formed. The new continent, Rodiniterra was formed.

The biota was simillar to previous period.

• Novoproterzoic (1250 ~ 788.8 ± 0.6 Ma)

Novoproterzoic is a last era of Proterzoic eon around 1250 to 788.8 ± 0.6 million years ago.

◦Tonoterran (1250 ~ 970 Ma)

Tonoterran is a first geological period of Novoproterzoic era arround 1250 to 970 million years ago.

Rodiniterra got broke up due to (geological) rift and formed into a new continent during 1150 to 1100 million years ago. Also at 1100 million years ago, boring billion ended.

At the beginning, stromatolites population went downfall. During early, the first Moruvozoiona appeared. Possibly true-animals also appeared at late.

◦Cryomundan (970 ~ 885 Ma)

Cryomundan is a second geological period of Novoproterzoic era arround 970 to 885 million years ago.

During 967 million years ago, the longest worldwide glaciation has occured due seperated Rodiniterra parts impacted each other. It caused volcanic europtions went chill into worldwide basalt fields, where sillicate mimerals turned into carbonate and absorb carbon dioxide (CO₂), which causes greenhouse effect went down. Also the sunlight was weaker than today. After the first cryomundan worldwide glaciation ends, the second golaciation happaned around 904.4 to 882.3 ± 5.9 million years ago.

In this geological period, first true-animals (or possibly late Tonoterran record) and Marealgaphyte (Orchophytes) appeared. After the first glaciation of this period, microcyanophyte replaced to algae (including marealgaphyte) dominated.

◦Dominozoanian (885 ~ 788.8 ± 0.6 Ma)
