Geological evolution of Mount Etna. The following is based largely on two recent publications see below and has additional information from other sources which are indicated in the text. Gillot, P. Acta Vulcanologica, 5: Tanguy, J. Prelude: Volcanism on the Hyblean Plateau Volcanism in eastern Sicily has occurred episodically since the middle Triassic, producing voluminous mafic that is, silica-poor lavas and clastic fragmental material, much of which was erupted and deposited below the sea level.
The sites of volcanic activity were located in the southeastern part of Sicily, on the Hyblean Plateau Monti Iblei , an area uplifted tectonically during the late Pliocene and Pleistocene. A notable feature of this volcanism was the brief duration of each eruptive event maybe a few years to several centuries and the lack of major volcanic edifices, all activity occurring from regional fissures controlled by the predominant tectonic trends WSW-ENE.
The products of the most recent episodes of Hyblean volcanism lie buried under hundreds of meters of late Pleistocene and recent alluvial sediments, and their precise age is not known, but it appears that there is a more or less continuous series of volcanics becoming progressively younger towards north. On the northern margin of the Catania Plain, an area of tectonic subsidence covered with fluvial deposits between Etna and the northern Hyblean Plateau margin, volcanic rocks outcrop again, but these are considerably younger than those of the Hyblean Plateau and are generally considered the earliest manifestations of volcanism in the Etnean area.
First phase: “pre-Etnean” Volcanic activity in the Etnean area began around 0. This initial activity, the first of four main phases during the evolution of Etna, was very similar in character to the latest Hyblean volcanism, and its products were mainly submarine lavas and volcaniclastics of tholeiitic composition for more info of this type of basaltic rock, see “The life stages of Hawaiian volcanoes” from Volcano World, and the geochemistry page about Loihi volcano, Hawaii.

Evolutionists generally feel secure even in the face of compelling creationist arguments today because of their utter confidence in the geological time scale. Even if they cannot provide a naturalistic mechanism, they appeal to the “fact of evolution,” by which they mean an interpretation of earth history with a succession of different types of plants and animals in a drama spanning hundreds of millions of years. The Bible, by contrast, paints a radically different picture of our planet’s history.
In particular, it describes a time when God catastrophically destroyed the earth and essentially all its life. The only consistent way to interpret the geological record in light of this event is to understand that fossil-bearing rocks are the result of a massive global Flood that occurred only a few thousand years ago and lasted but a year. This Biblical interpretation of the rock record implies that the animals and plants preserved as fossils were all contemporaries.
This means trilobites, dinosaurs, and mammals all dwelled on the planet simultaneously, and they perished together in this world-destroying cataclysm. Although creationists have long pointed out the rock formations themselves testify unmistakably to water catastrophism on a global scale, evolutionists generally have ignored this testimony.

Mount Etna, or Etna is an active stratovolcano on the east coast of Sicily, Italy, in the passages from the works of Gervase of Tilbury and Caesarius of Heisterbach (dating from the late Coltelli, M.; Del Carlo, P. & Vezzoli, L. (), “Discovery of a Plinian basaltic eruption of Roman age at Etna Volcano, Italy”, Geology.
In practice, each of these values may be expressed as a proportion of the total potassium present, as only relative, not absolute, quantities are required. To obtain the content ratio of isotopes 40 Ar to 40 K in a rock or mineral, the amount of Ar is measured by mass spectrometry of the gases released when a rock sample is volatilized in vacuum. The potassium is quantified by flame photometry or atomic absorption spectroscopy.
The amount of 40 K is rarely measured directly. The amount of 40 Ar is also measured to assess how much of the total argon is atmospheric in origin. Both flame photometry and mass spectrometry are destructive tests, so particular care is needed to ensure that the aliquots used are truly representative of the sample. Ar—Ar dating is a similar technique which compares isotopic ratios from the same portion of the sample to avoid this problem. Due to the long half-life , the technique is most applicable for dating minerals and rocks more than , years old.
And you know that it has decayed since that volcanic event, because if it was there before it would have seeped out. So the only way that this would have been able to get trapped is, while it was liquid it would seep out, but once it’s solid it can get trapped inside the rock.
Dome-like behaviour at Mt. Etna: The case of the 28 December 2014 South East Crater paroxysm
Because radiometric dating utterly refutes their biblical interpretations, young-Earth creationists YECs are desperate to undermine the reliability of these dating methods. As part of their efforts, YECs clearly believe that they can discredit K-Ar dating if they can show that excess argon routinely enters rocks and minerals as they form.
That is, they believe that excess argon will cause rocks and minerals that are supposedly less than 10, years old to have ‘deceptively’ old K-Ar dates of millions or billions of years. In particular, YECs attempt to demonstrate that excess argon is a ‘problem’ for K-Ar dating by locating examples of historically erupted volcanics, which yield K-Ar dates that are hundreds of thousands or millions of years older than their eruption dates.

Origin and differentiation of recent basaltic magmas from Mount Etna
Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life. Some so-called creation scientists have attempted to show that radiometric dating does not work on theoretical grounds for example, Arndts and Overn ; Gill but such attempts invariably have fatal flaws see Dalrymple ; York and Dalrymple Other creationists have focused on instances in which radiometric dating seems to yield incorrect results.
In most instances, these efforts are flawed because the authors have misunderstood or misrepresented the data they attempt to analyze for example, Woodmorappe ; Morris HM ; Morris JD Only rarely does a creationist actually find an incorrect radiometric result Austin ; Rugg and Austin that has not already been revealed and discussed in the scientific literature.
The creationist approach of focusing on examples where radiometric dating yields incorrect results is a curious one for two reasons.
