Results

My results from this analysis showed that rock type does not correlated with Sr ratios when group into four aggregate group types. Though it was useful to show why certain areas had relatively high Sr ratios compared to others. For instance, watersheds with relatively high Sr ratios also had higher percentages of granitic rock types. .
