Marble is metamorphosed limestone (calcium carbonate) and has been studied for other reasons many times. . 318-326; Hyndman, 1985,. While YECs explain geology by invoking talking snakes, magical fruit, and a mythical 'Flood Dalrymple (1969) discusses legitimate chemistry and fluid physics, which is hardly relying on flimsy 'rationalizations' or implausible excuses. . As discussed earlier, zoning and crystal growth are extremely important in understanding phenocryst ages.

These are found in high numbers, and at todays rates would take millions of years to form. The large numbers of these Po halo finds do indicate very quick changes in decay rates and that the rocks cannot be millions and millions of years old. . Obviously, Swenson, like many YECs, fails to realize that scientists can successfully unravel past events without witnessing them. . Lassen, California dated' at 130,000 years; erupted in 1915 AD and a basalt from Sunset Crater, Arizona dated' at 210,000 and 220,000 years; erupted in AD). What caused THE 'OLD' dates? The.8 million year old date also may have largely or entirely resulted from contamination. The description of another one of Austin's 'fractions' indicates that it is also highly impure: 'The 'heavy-nonmagnetic concentrate' (dome-1H) was dominated by orthopyroxene with much less clinopyroxene, but had a significant quantity of glassy particles attached to mafic microphenocrysts and fragments of mafic phenocrysts along. In reality, the Hualalai basalt had.60 x 10 to the -12 moles/gram of 40Ar. Brent Dalrymple is a geochronologist with 40 years experience, a pioneer in the identification of excess argon in igneous samples, and an outspoken critic of young-Earth creationism (e.g., Dalrymple, 1984). . This means trilobites, dinosaurs, and mammals all dwelled on the planet simultaneously, and they perished together in this world-destroying cataclysm. A Summary of the Million Dollar rate Research Project (Radioisotopes and the Age of The Earth). Depending upon the amount of zoned feldspars (which consist of older calcium-rich cores and younger sodium-rich rims) and the quantity of glass, amphibole and pyroxene impurities, the 'feldspar etc.' date could have any value between 0 and.8 million years under hypothesis #3. Has there been contamination into the rock of either extra amounts of parent or daughter elements? This method is used only on metamorphic and igneous rocks not sedimentary rocks (which are rocks laid down by water and is where the fossils are primarily found). For example, Austin, Snelling and Swenson all list the 'apparent K-Ar date' for mount etna carbon dating basalt the Hualalai basalt as '1.60 million years' instead.19 million years. . And the way this happened is the acceptance of millions of years, long before radiometric dating was developed. . Measurements in a blind experiment were taken that showed how much Helium should be left after certain amounts of time, at various heat levels of the rock and the diffusion rate of He leaving the crystal. Even if excess argon is present in a sample, YECs must still explain the ultimate origin of 40Ar. . Mountain fossil, young-earth creation geologists have long held that most sedimentary strata resulted from waterborne deposits during Noahs Flood. Swenson wants us to believe that Austin's critics (including me) are simply using invalid 'rationalizations' when we criticize Austin's dating of inadequately pure mineral/glass fractions. . A conservative estimate for the pre-Flood biomass is 100 times that of today. Austin clearly ignores the possibility of contamination in the mass spectrometer (hypothesis #2) and the possibility that the phenocrysts in his samples may be much older than the 1986 AD eruption (hypothesis #3). . You see, the radiometric dating techniques do not work when you can check the dates, but you should trust them when you cant check them. Austin cites a reference by Heliker (1995 which indicates that 3 of the. It is a definite pattern. How could he expect the relatively large and sometimes zoned minerals to be as young as the glass?! 52) concluded that excess argon may have no effect on the volcanics if they were to age over millions of years: 'With the exception of the Hualalai flow which contains noticeable ultramafic xenoliths, Dalrymple, 1969,. 1967 have suggested that large phenocrysts in volcanic rocks may contain excess 40Ar because their size could prevent their being completely degassed before the flow cools. .

In contrast, stellar atmospheres have 36Ar 40Ar (Krauskopf and Bird, 1995,. Additionally, somewhat older xenoliths (foreign rocks) and xenocrysts (foreign minerals, for example, Hyndman, 1985,.

Institute for Creation Research, El Cajon and Creation Research Society,. Austin also states: 'The 'heavy-magnetic concentrate' also had glassy particles (more abundant than in the 'heavy-nonmagnetic concentrate. Therefore, IF hypothesis #1 was the only factor influencing the dates of Austin's samples, I would expect the hornblende-rich 'fraction' to provide an older date than the pyroxene- and feldspar-rich 'fractions.'  Because Austin's amphibole-rich 'fraction' has a younger 'date' than the pyroxene-rich 'fractions these results.

Kostenlose porno movies thuisontvangst enschede Austin even admits that the dacite is 45 phenocrysts and 'lithic (rock) inclusions.'  Considering how messy this dacite is, separating the glass from the mineral matter may not even be possible for this sample. Helens' dacite, this glass formed in submarine (ocean floor) basalts under high hydraulic pressures (Dalrymple and Moore, 1968). . In order to get the level of helium found in the rocks, there had to have been a lot of radioactive decay.
