West Africa is emerging as a new region of potential iron ore producers as large scale projects are being pursued by the majors and junior projects come on stream. 

Juniors have been able to enter this market despite infrastructure challenges with capital coming from external parties mainly the Chinese attracted by the large scale infrastructure opportunity. 

Happy is he who knows the origin of things. Thus wrote the Roman poet, Virgil, many centuries ago. He may have said this as he puzzled over the many myths and legends that describe the beginnings of the earth and the human species. The urge to explain origins is strong, and the absence of facts did not deter ancient peoples from inventing myths to satisfy the need.

The beginnings of historical research came mostly by necessity as hereditary ruling dynasties felt a need to establish their rights to govern or own property. The Egyptian monarchs, for example, believed themselves to be descended from gods and needed proof of their lineages.

This is intended to be a reference manual for Geotechnical Engineers. It is principally a data book for the practicing Geotechnical Engineer and Engineering Geologist, which covers:

• The planning of the site investigation.

• The classification of soil and rock.

• Common testing, and the associated variability.

• The strength and deformation properties associated with the test results.

Seismic numerical modeling is a technique for simulating wave propagation in the earth. The objective is to predict the seismogram that a set of sensors would record, given an assumed structure of the subsurface. This technique is a valuable tool for seismic interpretation and an essential part of seismic inversion algorithms. Another important application of seismic modeling is the evaluation and design of seismic surveys. There are many approaches to seismic modeling. We classify them into three main categories: direct methods, integral-equation methods, and ray-tracing methods.

There is a vast difference between a structural engineer and a geotechnical engineer in terms of the material being used. A structural engineer defines the properties of the concerned material, such as concrete or steel, and carries out only a limited number of control tests according to the required standards. In contrast, the material used by a geotechnical engineer is natural and thus, by definition, it can be spatially heterogeneous and, in composition, it can be multiphasic, discontinuous or even anisotropic. This leaves the geotechnical engineer with no choice but to accept it as it is and to accommodate themselves to it. Moreover, while developments in numerical modeling depend increasingly on specific advanced test parameters, soil testing programs remain limited because of the competition between contractors to reduce costs and time.
