Sumario:The selected outcrops shown in the fieldtrip correspond to 1) braided palaeochannels, with preservation of composite bedforms that build up alluvial islands and sand flats : 2) longitudinal and transverse sections of point bar bodies, three dimensional outcrops of meander loops chute channels 3)The evolution of the Tortola fan as the base level was rising, culminating in extensive gypsum deposits, 4) gypsum deposits with chert, in order to observed important bioturbation structures in particular.
