The chronometric scale is based on the measurement of certain physical properties of the rocks, generally the relationship between the content of stable isotopes and unstable isotopes of the same element (for example, 40Ar/39Ar) or the relationship between the content of certain elements generated by radioactive decay of other elements (for example: U/Th/Pb, Rb/Sr or K/Ar). An absolute age is obtained using the appropriate measurement techniques. The results present some uncertainties. In the year 1982, the beginning of the Cretaceous was established at 130 million years from now, while in the current table it has been established at 145.5 million years.

The principle of superposition of strata is the basis of the chronostratigraphic scale. The upper and lower layers of a group of strata are characterized by their fossil records. A scale of validity can be obtained if each group is given a name.

The proliferation of this class of units made it clear that there was a need to establish standard units that had global validity, to each of which the ICS agreed to give it a name. Applying the aforementioned methodology, the history of the Earth has been subdivided into three higher order units or eons, which, from oldest to most modern are: Archaic (between 4,000 million years and 2,500 million years); Proterozoic (between 2.5 billion years and 542 million years) and Phanerozoic (between 542 million years and 0 million years; present).

The first two eons are grouped together in an informal unit called the "Precambrian".

The Phanerozoic eon is divided into three smaller units or “eras” that, from oldest to most modern, are called: – Paleozoic Era or “Paleozoic” (between 542 million years and 251 million years), which includes six periods that go from the Cambrian, in the base, to the Permian, in the upper part.– Mesozoic Era or “Mesozoic” (between 251 million years and 65.5 million years), which includes the periods called Triassic (between 251 million years and 199.6 million years), Jurassic (between 199.6 million years and 145.5 million years) and Cretaceous (between 145.5 million years and 65.5 million years). – Cenozoic Era or “Cenozoic” (between 65.5 million years and 0 million years; today), which includes the periods called Paleogene (between 65.5 million years and 23.03 million years) and Neogene (between 23.03 million years and 0 million years; present).

Each of the periods is subdivided into several “epochs”, which are generally named according to their position within the respective period (for example, Lower Cretaceous, between 145.5 million years and 99.6 million years) or have a proper name that is current (for example, Eocene, between 55.8 million years and 33.9 million years) or sometimes retains its obsolete name (for example, Lower Jurassic or Lias; Middle Jurassic or Dogger).

The Kimmeridgian is an age from the Late Jurassic or Malm epoch.

Regarding the origin of the nomenclature of the various units, the names of the eons and eras refer to the types of life that developed on Earth at that time (for example, "Mesozoic", from the Greek "animal life"). intermedia"), while epochs are named either from their stratigraphic position (for example, "Late Triassic," meaning that it lies stratigraphically above the "Middle Triassic"), or have a complex history that includes personal considerations of the authors who defined them (for example, "Miocene", used by Charles Lyell in 1833, to refer to the second lower division of the four that he established in the southwestern zone of the Paris basin).

Ages are named for the area where the type series or pattern section was defined.

The black and white horizontal stripes on the Geological Time Table represent the magnetic polarity at a given moment in the Earth's history. The column records reversals of the Earth's magnetic field.

In this column, the black bands indicate "normal polarity" (meaning that the magnetic North Pole is in the vicinity of the North Pole of the Earth's axis of rotation) and the white bands indicate "reversed polarity" (the magnetic North Pole is It is located near the south pole of rotation of the Earth). The units of time are formed by a combination of "normal" and "reversed" events, which can be correlated with the scale.

By measuring the orientations of magnetic mineral particles, which many rocks have, the "chronos" can be identified and can be dated.

The Table of Geological Times has two more columns. The variations of the sea level are represented by a correlatively next to the columns of the Paleozoic, the Cenozoic and the Mesozoic. This curve allows us to see that the sea level has always been above the current level, for example, 80 million years ago, the sea level was around 350 meters above the current level.

The other column is located to the right of the Neogene detail and bears the heading 18OPDB of seawater. This curve was obtained by analyzing the amount of oxygen isotope 18 found in carbonate shells of certain unicellular organisms of marine life.

In warm weather, the amount of O18 that accumulates in the shell of those organisms decreases, while in cold weather, the amount increases. A curve is obtained that shows the maximum peaks and minimum peaks that correspond to periods of cold weather and warm weather.

Graphically, in the table of geological times, the chronostratigraphic units (eons, eras, periods, and ages) are represented by a color chart that follows UNESCO international standards (for example, the Triassic is represented in reddish tones; the Jurassic in a range of blues or the Cretaceous in a scale of greens).

A randomized parallel trial is being conducted to examine the effects of consuming a diet rich in saturated fat, a diet rich in MUFAs, or a MED diet for 8 weeks on metabolite profiles in 47 subjects at risk of metabolic syndrome.

Before and after the intervention, 162 serum metabolites were evaluated. The evaluation was done using a targeted platform.

Fifty-two metabolites are changed during the intervention. Both the MUFA diet and the MED diet lower the same LDL fractions.

The MED diet reduces the VLDL subclasses, VLDL-related fractions, and VLDL Triglycerides.

The study showed that the concentration of LDL particles decreased in all three subclasses and several related fractions, as well as a decrease in small LDL concentration.

The ApoB/ApoA1 ratio was increased by MUFA. The effects on cardiovascular disease risk factors are favorable.
