@all Dating freshwater calcium carbonate bioherms in a lake like Fayetteville Green Lake can be challenging, as you've mentioned. Traditional radiocarbon (C14) and uranium/lead dating methods are typically more applicable to marine environments or materials with higher organic carbon content. However, there are alternative methods and approaches you can consider for dating freshwater bioherms:

Given the unique challenges of dating freshwater bioherms, it may be necessary to use a combination of these methods to establish a reliable chronology for the growth periods of the bioherms in Fayetteville Green Lake. Each approach has its limitations, but together, they can provide valuable insights into the lake's history.

@all Dating calcium carbonate bioherms in a freshwater source like Fayetteville Green Lake can indeed present challenges, especially when traditional methods like C14 or uranium/lead dating may not be applicable. Here are some alternative methods and considerations you might explore:

It's important to note that the success of these methods depends on the specific characteristics of the bioherms and the surrounding environment. Collaborating with researchers who specialize in dating methods and the geology of freshwater systems could enhance the accuracy and reliability of your findings. Additionally, obtaining multiple lines of evidence using different methods may strengthen the overall reliability of the chronological information obtained.
