Dear friends of Science Astronomy and geo-astronomy,
Differentiations of meteor from rest of the mix-up stones - what's the truth?

Many a times we do make mistake to identify Meteors and igneous Lava rock.
either because of the lack of the knowledge or understanding. only the person
who collects the sample can put the light on the verification. eg Samples
collected form the regions of Lava stones, one has to be careful for selection
of the samples. as Lava stones are also having high density stones. also with
the shiny metallic appearance as well as some magnetic properties as well. and
if the Samples are very old than it really becomes difficult as the
radioactivity of the short half life elements of the meter loose their identity.
In such a case only physical properties like magnetic and metallic and specific
gravity gives the clue and chemical analysis only reveals the truth.

Some one may make mistake by just looking it as an ordinary igneous stone but
that is really their mistake because of lake of knowledge and information. and
when NON-GEOLOGIST is likely to make the most mistake of the
identifications.Specific gravity higher than a Lava stone and nearly equal to
that of Iron is a good clue with its metallic property and magnetic
characteristics. (Team work with Geologist and Physicist - atomic researchers
with chemical analyst gives better results )

But when the Sample is collected from a Sediments area of the fossil formation
and where there are no trace of the igneous rocks in that area. even a single
sample well collected is well identified as it completely differ from the rest
in appearance and physical characteristics as mentioned above.

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 iformation 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.
