Abstract
The Decaturville Structure on Highway 5 in Missouri was established as a meteor impact site in 1979 by a USGS study funded by NASA. While this report did give an age range, the range was about 250 million years. By using U/Th-He Apatite thermochronology, which looks at the decay of U/Th into He inside the apatite minerals. The purpose of this study is to: constrain the age range of the formation for Decaturville. One of the features of an impact site is an uplifted block at the center. This uplifted block was displaced nearly 300m at Decatureville. While these rocks where being displaced, the apatite minerals passed through their blocking temperature and started the isotopic clock by trapping He.
Biography
