| Up until 2013, the uncertainties in the geochronologic dates had been too coarse to confirm the volcanic eruptions were correlated with major climate changes. |
| These are used in geochronologic and thermochronologic studies. |
| There are three issues resulting from the geochronologic extension of fossil Holometabola to the Pennsylvanian-Mississippian Subperiod boundary or even earlier. |
| Our new geochronologic data reported here both complement and support prior geochronological work on the metamorphic history of the Sudetic high-grade terranes. |
| However it is not clear how these units are related to each other because of poor exposure and lack of detailed geochronologic data. |
