Number of pages: 169
This volume summarizes the main scientific results of expeditions to the tepuis of Venezuela between 2002 and 2011. The major research described in this monograph is dedicated to the great caves discovered in Roraima and Churi tepuis. The geological research was accompanied by biological research on cave and surface fauna, with a special focus on malacofauna, herpetofauna and insects. Although some of the data from this research has been previously published in scientific articles, it did not always obtain the justifiable space to present all gathered documentation and to elucidate all relevant scientific problems from a greater perspective.

Lyell, while still a young man, determined that he would endeavour to put geology -- then only beginning to rank as a science -- on a more sound and philosophical basis. To accomplish this purpose, he spared no labour, shrank from no fatigue.

The U.S. ranks third, behind Indonesia and Japan, in the number of historically active volcanoes. A few volcanoes have produced some of the largest and most dangerous types of eruptions in this century, while several others have threatened to erupt.

Where do they come from? What are they made of? How can they be distinguished? What is their value? The subject as a whole has been treated from the mineralogical standpoint, as this affords the best basis for a thorough knowledge of gems.
