Question

I absolute dating principles to our local New exico geology. You are been provided a diagram from the Sandia Mountains and the associated legend (Figure 7), isotopic data from rocks from this region (Table 4), graphs tha represent the percent of parent atoms remaining versus elapsed time (Figure8d e and a geologic time scale (Figure 10) East West Abo Formation Madera Limestone andia Fomation Fault Sandia Granite Andesite dike Sierra Ladrones Form atio Metamorphosed / volcanic rocks Zia SandstoneMet Sandstone with grante pebbles and rarey limestone pebbles E Essa Metamorphic rock Granite }Sandstone Key to rock types: Limestone I view of the geologic features Mountains. Isotope System A Parent atoms-Daughter Isotope System B Parent Daughter | 90 Parent

Explanation / Answer

22. Please provide the table 4

23. Please provide the table 4

24. For system A, at 1200 million years the parent atom remaining is 50%. So the half life of isotope system A is 1200 million years.

For system B, at 60 million years the parent atom remaining is 50%. So the half life of isotope system B is 60 million years.
