BLOCK ROTATION IN THE CENTRAL RANGE FAULT SYSTEM, CARIBBEAN-SOUTH AMERICAN PLATE BOUNDARY, TRINIDAD
Paleomagnetic samples were collected from 22 sites across the Central Range from the Tamana and Pointe-a-Pierre formations. Due to poor outcrop most sites were collected in quarries where continuous stratigraphic sections were clearly visible. Five to ten cores were collected at each site and were analyzed using the alternating field demagnetization process. In most samples demagnetization revealed a single magnetization component. The samples have a weak magnetization signal, on the order of 10-4 mA/m. Initial results suggest a significant amount of vertical axis block rotation in the Central Range. Samples were collected to perform a fold test from the Tamana formation, and samples were collected from the Chaudiere formation to perform the conglomerate test. Results of these tests should constrain the age of magnetization.
