So how come I started this whole thing by saying that it’s actually not possible to date fossils directly? Because although radiometric dating will almost always provide an answer, in most cases, unless you’re applying the methods to an igneous rock, it won’t answer the question you’re asking.

See, the clock for radioactive elements starts at crystallization.

So we know that C came before D—but because D is igneous, we can put a date on it (now I have a Beyoncé song in my head, great…).So, in sum: C-14 is great if you’re Indiana Jones (who, for once and for all, was an , not antiques-looting Nazis.). You wouldn’t know—and this is all about knowing just that.Yes, we’re back to relative dating principles—but this time, with numbers!-Correlation by fossils- same fossil or fossil assemblage in widely separated rocks are same age. age of rock = number of half lives gone by X half life of isotope pair used How old is the Earth?

The shorter the range of the fossil, the more accurate the correlation. -oldest rocks dated are from Greenland, Minnesota, etc.

And that makes all the difference because once we know the absolute dates of the relevant igneous rocks, we can parlay that information into giving us a range for the possible absolute dates of the fossils.



I have another table B containg 10000 records of incremented and edited records of A table. I am using the following codes to append data from B to A.--For incremental/New data-----insert into Aselect * from B where column_name NOT IN(select column_name from B);--For Edited Data-------cursore C_ABselect * from Aminusselect * from AFor R in C_ABloop Update A set....where ..loop End; It's working but taking a huge time/sometimes hang the computer. to update 10,000 rows in a 100,000 row table should take seconds (it'll be a direct function of the number of indexes). The number of rows in both the tables is same after porting.… continue reading »
