      Vegetation and soil properties of an iron-rich canga (laterite) island on the largest outcrop of banded-iron formation in Serra de Carajás (eastern Amazonia, Brazil) were studied along a topographic gradient (738- 762 m asl), and analyzed to test the hypothesis that soil chemical and physical attributes play a key role in the structure and floristic composition of these plant communities.

    • Concretions, Thunder Eggs and Geodes

      The shape of an ironstone concretion often depends on the way a shale or sandstone bed breaks up into regular blocks of various sizes under the action of weathering. This separation takes place along natural planes of weakness in the rock such as horizontal bedding surfaces and vertical joints (cracks).
