The Hoggar, which forms the Algerian part of the Tuareg shield, is an ideal site for geoscientific studies. As the site of successive orogenies, it offers a single example of the problems that arise on a continental scale, whether in terms of magmatism, metamorphism, structure, metallogeny or geophysics.

China is an emerging superpower, with a huge demand for raw materials and mineral resources that are being used to increase the standard of living conditions for its residents and bolster its surge forward in the global economy. To enable this rapid growth, China is also undertaking an education revolution with the help of experts from around the world in many different fields of endeavour.

The monograph Geology of Cuba addresses different facets of Cuba’s geological knowledge: cartography, marine geology, fossil record, stratigraphy, tectonics, classification of its ophiolites, quaternary deposits, metallogeny, and minerageny. The contributions are not linked by a common thread, being free versions according to the scientific positions of the authors; therefore, logically, there are contradictory opinions in many cases. However, it is a fabulous scientific work that puts in the hands of the most diverse readers all the wealth of geological knowledge of Cuba, essential for any type of application, exploration, teaching, research, or patrimonial. In itself, it constitutes a notable contribution to the advancement of knowledge of the Geology of Cuba.

. Based upon early field studies within the Macarena range and the Roraima tepuis, Augusto Gansser documented the puzzling relationships between the Guiana Shield and the Andean belt, in the process formulating the “Roraima Problem” from a geomorphologic-stratigraphic standpoint.

Interest in the plastic deformation of rocks arises mainly from its application in the Earth sciences, especially in structural geology and tectonics. Its experimental study has consequently been pursued mainly in laboratories associated with geology or geophysics departments or institutes. However, the physical mechanisms involved are of considerable interest in materials science and some workers in the field of rock deformation have had a materials science affiliation.

Molybdenum (Mo) is a transition metal with an atomic number of 42 and a relative atomic mass of 95.95. Important isotopes are 95Mo, 96Mo, and 98Mo. Molybdenum has a high melting point of 2623
C and one of the lowest coefficients of thermal expansion among commercially used metals. It readily forms hard, stable carbides in alloys and is widely used in steel alloys, including high-strength alloys and superalloys. Molybdenum was discovered in 1781 by Peter Jacob Hjelm and the name is from the Greek “molybdos,” which means “lead,” because it was often confused

with lead. Details on the chemistry and uses of molybdenum can be found at www. rsc.org/periodic-table/element/42/molybdenum.

The Eocene Green River Formation in Wyoming has long served as a standard for lacustrine depositional systems. This lacustrine formation, excluding the culminating phase, was deposited in a closed hydrographic basin. The position of the boundary between lake and mudflat margin was dictated by the inflow evaporation ratio (inflow greater than evaporation = transgression; inflow less than evaporation = regression).
