Question from a novice , about Uranium Thorium dating of stalactites /
speleotherms .
  Having spent some time online google searching ,  I m still not sure
if it is possible to date relatively recent '' calcite deposits ''
using modern uranium thorium method , it clearly being done on samples
much older , within the archaeology field it has been used to date
rock art  30,000 plus years old  .

.
this '' old iron tool ''  was found in an old mine site ,    I NOTE
there is a  modestly  thick and visible layer of  ''calcite  sand
grains''  on it ,  that fell from the roof and or sides of the old
mine ,  before the mine collapsed and buried the '' old iron tool ''
on the  site with the entire mass  then set into a conglomerate  of
mixed minerals  as shown here .

.
my questions are assuming iron tools must be aged from  between about
5000 years old and  may be  relatively  very recent , can existing
tests date  the  '' cave popcorn ''  accurately  , withing this
rather young age  range , certainly  a lot less than 5000 years ?
1.  would it be possible to date this  '' cave popcorn '' calcite
sand
 2. and where in australia can I have this done ?,
 3. and how much would it cost  ?
 .
Cave popcorn, or coralloids, are small nodes of calcite, aragonite or
gypsum that form on surfaces in caves, especially limestone caves.[1]
[2] They are a common type of speleothem.[1][2]
