Dear friends of Science, Isotope study, Astronomy Geology and Chemistry,
Carbon Dating has limitations of time as C14 has half-life of about only 5730
years samples of up to 50000 years old e. g. only for archaeological and
Anthropological purpose can be carbon dated but not the fossils of Million
years. we need more longer Half life radio Isotopes for those fossil dating for
longer than a Million of years. so as for A meteor also and Ir - IRIDIUM has
very short half life too.

Subject: Crocodilians in KUTCH



Dear Science Friends,


I would like to write YOU all of our expert GEOLOGIST, Archaeologists and
ANTHROPOLOGIST on the subject of the new Geological researches. WE have seen
fossils of "Crocodiles" in "GUNAWARI" at GANGESWAR Dome. Shree DAS surveyed
KUTCH for ONGC mission and on mining project for ONGC. He observed the
importance of KUTCH on geological science. some of the fossils he declared as
Mesozoic (Ammonites +208Mn years and some CROCODILES "cretaceous period" 140 Mn
years together at the same place with a VAST time difference of more than 65Mn
Years). Some experts are in favour of those DINO "Supercroc " are Prejurassic -
Triassic +200 Mn years rather than "cretaceous period" 140 Mn years.What we are
thinking of the Fossils of the "crocodiles" are actually the ancestors
(10-12meters size and according to the wildlife expert David Attenborough
"Marine Dinosaurs") of the present time Crocodiles of 4 meter size. some
describes as "CROCODILIAN" ancestors of many species and that of crocodiles and
some explain as "Supercroc" "DINO". Those "sarcosuchus" ancestors of crocodiles
had protruding teeth and armoured plate and lifespan of more than 110 years
compared to 70 years of present life span of the crocodiles. Mesozoic Ammonites
+205Mn years and some CROCODILIANS of the "cretaceous period of - JUNGLES IN
KUTCH" +140 Mn years together at the same place with a VAST time difference of
65Mn Years makes us to re-think about the time scale and to understand geology
of KUTCH, wildlife, environment, history and fossils history. Perhaps we need to
ask our expert geologist Shree DAS to visit KUTCH again and give us an expert
second opinion on the subject to support the New research of Kutch geology. I
think this time every one should consult such an experts who are in our touch
and known to us to give their advise for the benefit of the science of Geology.



Many of learners do make to mistakes and do not do the real test for specific
gravity and metallic characteristics in old collected samples. and they loose
the track to identify those. and later on only Chemical analysis reveals the
truth and need for further specific analyses test for Ir -iridium and Fe Ni and
if any radioactivity if it persist after the long time as the only one isotope
of Ir - Iridium has the bit longer half life time. so also difficult to find the
actual information of the period except the following isotope only, In such a
case where identifications becomes difficult by Physical research laboratories
those are sent for the further verification to the radio isotopes research labs
in Jaipur for Indian sample analysis.

Carbon 14 slowly decays by changing back to nitrogen and so releases energy. A
ratio of carbon 14 to common carbon, is very similar in a leaf to that in an
animal's body, to that in the atmosphere. But when a plant or animal dies, the
carbon 14 decays as time goes by.Carbon 14 dating cannot be used to date rocks,
but only on things that were once living. There are a number of factors which
alter the results of the carbon 14 method: One is the differing amounts of
cosmic rays reaching the earth. Another is that the earth's magnetic field is
decreasing, which deflects cosmic rays. Also, the Genesis flood would have
changed the carbon balance. The ratio before the flood had to be lower than what
it is now.Added to that, volcanoes give out a lot of CO2 which is very low on
carbon 14, & many Creationist researchers belief that there was a lot of
volcanic activity at the time of the flood.

In theory, anything over about 50,000 years old, should have no detectable
carbon 14 left. So if something has been dated by a different method, which
gives a date of millions of years old, and it contains carbon 14, then that is
good evidence for it not being that old. So the carbon-14 dating method can be
useful, provided these factors are taken into consideration.

Remember, a specimen older than 50,000 years old, should have so little carbon
14 that it won't be measurable. Evolutionists say that the youngest coal is
millions of years old, (and they say that most is 10's or 100's of millions of
years old). But no source of coal has been found that completely lacks carbon
14. This seems to be an unsolvable mystery to evolutionists. ...if radiocarbon
is routinely present in coal, oil, graphite & diamonds, then the Earth cannot be
billions of years old..Furthermore, ice cores only yield chronologies of many
thousands of years by assuming the layering is due to annual cycles."

Earth Has plenty of Carbon Isotopes and may contaminate samples too. Phase two
fossils and so. Fossil wood found in "Upper Permian" rock was dated at 250 Ma
(Mega annum, million years) old still contained carbon 14!. "If nuclear decay
rates have not been constant in the past, then not only is radioisotopic dating
of rocks rendered useless, but many fundamental universal physical constants
would have been affected." Surely these things ought to cast doubt on us relying
on these dating techniques?

More about Carbon Dating


In the 1940's Dr. Willard F. Libby invented carbon dating for which he
received the Nobel Prize in chemistry in 1960.

Carbon dating has given archeologists a more accurate method by which they
can determine the age of ancient artifacts. The halflife of carbon 14 is 5730 ±
30 years, and the method of dating lies in trying to determine how much carbon
14 (the radioactive isotope of carbon) is present in the artifact and comparing
it to levels currently present in the atmosphere.

Above is a graph that illustrates the relationship between how much Carbon
14 is left in a sample and how old it


Actually is Radiometric Dating?
These are methods that estimate the age of rocks by using the decay rates of
radioactive elements. For example; Potassium 40 decays to argon 40. Uranium 238
decays to lead 206 (via other elements like radium). Rubidium 87 decays to
strontium 87.


The original element (the 'parent') decays more and more to the second element
(the 'daughter'), so the older the rock the greater amount of 'daughter'
material is produced. Each parent has an assumed half-life figure (in years), a
50% decay figure. For Potassium 40, this is reckoned to be about 1.3 billion
years.
