This project will investigate a portion of eastern Bolivia, where the rocks have escaped both Andean tectonics and rifting associated with the opening of the Atlantic ocean. The project is aimed at providing robust paleomagnetic poles for the time period 1.0 Ga- 540 Ma and ancillary age and stratigraphic control. Successful results will be applicable to many continued-wide problems of paleogeography and paleoclimate of the southern hemisphere. ; Oh +' 0 $ H l D h R:\WWUSER\TE MPLATE\NORMAL.DOT S u m m a r y I n f o r m a t i o n ( 9526709 Felicia Smith Felicia Smith @ @ @ @ Microsoft Word 6.0 1 ; R R ! !
