The Core Accretion Model of Planet Formation
Mass sinks in time, into stratified layers of sediment: a solid core on fire in the darkness, sunk in the shadow of death.(Job 28:3) MP Technical Paraphrase
We have a Biblical basis for the core accretion model and the origin and timing of Precambrian fossils which were deposited synchronously with the formation of an Oxygen-rich atmosphere.
On the second day God created gravity and initialized the process which popular science (SciPop) SciPop likes to call the core accretion model. The Earth was deposited as concentric layers of sediment around a gravitational singularity.
And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so.(Genesis 1:7) KJV
In the Biblical narrative this is taking place as the firmament separates the waters above from the waters below. We have evidence of this happening at the same time that an gaseous, Oxygen-rich, atmosphere formed in sediments known as the Banded Iron Formations. Scientists are getting up to speed and have presented evidence that the Earth was covered with water at this time.
For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water:(2 Peter 3:5) KJV
If the inception of gravity was the creative act of the second day, and it’s the mechanism by which the waters above the firmament were separated from the waters below it, then we have 2 predictive, testable hypotheses and a narrative which is a simple plugin replacement for the SciPop core accretion model.
Earth’s rocky core formed first, with heavy elements colliding and binding together. Dense material sank to the center, while the lighter material created the crust. The planet’s magnetic field probably formed around this time. Gravity captured some of the gases that made up the planet’s early atmosphere.– The Core Accretion Model (SPACE.com)
- Precambrian sediments will contain fossils of unusually large size compared to their modern counterparts,
- Precambrian formations will include concentric Iron-rich layers that have worldwide distribution, the Banded iron Formations,
- IF God created gravity on the 2nd day in a primordial soup containing the complete array of inorganic and organic chemistry, and a diversity of cellular and multi-cellular life,
- AND this happened as an Oxygen-rich atmosphere formed,
- THEN we should find formations of finely bedded sediment high in Iron and other oxides in the Precambrian.
Gravity made the waters of the deep contract and become spherical. The densest matter made of the heaviest elements sank towards the center, causing displacement of the lighter forms outward and establishing concentric layers of sediment.
We would expect the geological sequence to start with basal metamorphic rock that has no fossils of any kind. Photosynthesis was taking place during the 1st day so there was abundant dissolved oxygen and other gasses present. The firmament crystallized far out in what we call space while the earth continued to contract, so an expanse opened up below the firmament causing dissolved gasses to come out of solution. As this happened there were many kinds of chemical reactions taking place, including the combination of iron (Fe2+) with Oxygen (O2-) to form iron oxides. These precipitated out of solution and were deposited in concentric layers. These layers are basal, although not the lowest, and may be metamorphosed.
Linear belts of Precambrian rock composed of banded mixtures of chert and a variety of iron-bearing minerals. They typically occur in belts hundreds to thousands of kilometres long, up to several kilometres wide, and with thicknesses as great as 600m. The rock successions in which these iron formations occur usually lie above high-grade metamorphic rocks, but the iron formations are generally not the basal units in the succession. Banded iron formations occur in the oldest rocks still preserved on earth, about 3.8 billion years old.
It seems likely that some of the iron formations now on the borders of the different continents were originally part of a single depositional basin before being separated by continental drift. Where the general geologic setting has been studied in more detail, a comparison of iron formations on opposite continents fits fairly well with the assumption of originally coherent iron-formation belts. The type and depositional environment of these iron formations with their associated rocks are similar, if not identical, and so are their ages and metamorphic histories.
In the Labrador Geosyncline the iron formation occurs as a continuous stratigraphic unit more than 1,000 km long before being disrupted by erosion or structural features. Apparently, a single iron-formation unit was once present around the entire shoreline of the Ungava craton for a distance of more than 3,000 km. It is evident that the factors that led to the deposition of the iron existed on a very broad scale and were a major part of the tectonic framework of the time. What is the mechanism for the episodic generation of intensely iron-rich laminae over such extensive areas? Why has this not occurred during the last 800 million years? As yet there are no satisfactory answers to these questions.
The source of the silica in all banded iron formations is probably the same. There is abundant evidence found in the thick banded chert masses to indicate that the silica was precipitated as a gel that later hardened and crystallized to form chert. Syneresis or shrinkage cracks, septarian structures, lenticular cracks, or desiccation cracks that have been distorted during compaction all indicate that the silica was deposited as a gel and later dehydrated and compacted. Many slump structures, folds, and slips confined to single beds or to a restricted group of beds indicate penecontemporaneous deformation of very soft and incompetent beds.– Banded Iron Formations, Blatt, Harvey (1982) Sedimentary Petrology
