Venezuela - Ciudad Bolivar in the narrowness of the Orinoco River

Ciudad Bolívar in the narrowness of the Orinoco River constitutes a cultural landscape located in the shores of the third mightiest river of the world, the Orinoco, and in the Imataca Complex, a rocky platform of 3,400 million years of age, which makes it the oldest geological formation in the planet. From a geographical point of view, unique characteristics are found in the small context of the river basin, like the great granite outcrops, located in both margins of the channel, associated to human settlings and a long history of transformations, as much in the site that occupies Ciudad Bolívar, as in the other border where the neighboring population of Soledad is located. In addition, this zone also shows intrusions of Mesa Formation in Guayana’s territory, a geological formation characteristic of the Venezuelan Central and Eastern “Llanos” or Lowlands, which dates from the Pleistocene (around 1 million to 10,000 years ago), constituting edaphologycal evidence of a particular time in the natural history of the country in which great part of its Eastern territory was comprised in an extensive delta zone, much greater than the one present at the Orinoco nowadays .
