The higher elevations on the shield are called the Guiana Highlands, which is where the table-like mountains called tepuis are found. The Guiana Highlands are also the source of some of the Region: South America.

This map represents a new kind of geologic interpretation of the Venezuelan Guayana Shield. It is an important new contribution (and crucial to the resource assessment) because the distribution of mineral resources is controlled by generally hidden geologic features such as deep faults, shear zones (single and intersecting), volcanic calderas.

Staving off the dreaded resource curse, Venezuela has paved a new road to success. Key to sustaining this progress is the country’s ability to maintain its own mineral wealth.

Venezuela sits on mineral reserves of gold, iron ore, diamonds, coal, uranium and the precious mineral coltan. Coltan is Venezuela’s Oro Azul or ‘blue gold’. It may be doubted that Venezuelan paleontologists, without external prompting, would have made special studies of the small planktonic species.

Fortunately, the Trinidad workers published several papers in ‑ which drew attention to the limited ranges of many species of the Globigerinidae, Globorotaliidae and their allies.
