Microscopic observation and identification of minerals in thin section is the most essential part of a geological study. All the students and  searchers working with rocks or sediments (petrologists, tural geologists, engineering geologist, hydrologist etc.) need to structural its mineral composition and fabric. However, many professional ists and students try to avoid thin section study. This is because geologist and students try to avoid thin section is time consuming and they do not know the preparation microscopic procedures. Many graduate students faced apporpriate section spend considerable time wondering where to start <...>

The term geology is a combination of two Greek expressions: “Geo” refers to the earth, and “logos” refers to the logic and language used to explain your observations. So think of geology as a way to organize and explain the earth processes that we see all around us. For some of the strange shapes we see, an educated explanation would be great. Most of what we know is good guesswork, based on lab experiments and inferences that take many detailed drawings to explain and a lifetime to understand. Fortunately, the more you see, the better things fall into place. <...>

Illustrated Pollen Terminology is a collection of palynological terms and wellillustrated with light and electron microscope images. The focus of this book is on the pollen of seed plants, predominantly angiosperms; therefore, it rarely explains features unique to spores or gymnosperms. A strict rationalization of terms on the basis of practical criteria has been attempted for this book. Where necessary, definitions have been reworded, newly circumscribed, or brought into focus. In addition, consistent application of EM techniques and the nowadays better understanding of pollen features have made redefinition of some terms necessary <...>

The countries of the Middle East (Fig. 1.1), the region reviewed in this book, cover parts of the lands of the eastern Mediterranean and the greater part of Arabia (Arabian Shield, Arabian Platform and Arabian Gulf), and the western Zagros Thrust Zone, an area enclosed between 13 ° and 38 ° N and 35 ° and 60 ° E (Figs. 1.2 and 1.3). Topographically, the higher elevations generally lie to the west in the Arabian Shield and pass eastward into the lower-lying areas occupied by the Arabian (Persian) Gulf and the Tigris-Euphrates Valley.

In the latest book published in this series, Geophysics for Petroleum Engineers, written by Professor F. Aminzadeh and Dr. S.N. Dasgupta, I had the pleasure of providing a brief preface that emphasized the strong need to maintain and improve lines of communication among and between modern reservoir, drilling, and production engineers and geophysicists, geologists, and petrophysicists. That volume, produced by experts in the geosciences and engineering within industry and academia, was designed and written with alleviating the traditional communication gap between the disciplines and asset team members firmly in mind <...>

Subsurface geological features of interest in hydrocarbon exploration are three dimensional in nature. Examples include salt diapirs, overthrust and folded belts, major unconformities, reefs, and deltaic sands. A two-dimensional (2-D) seismic section is a cross-section of a three-dimensional (3-D) seismic response. Despite the fact that a 2-D section contains signal from all directions, including out-of-plane of the profile, 2-D migration normally assumes that all the signal comes from the plane of the profile itself.

Active tectonics is the study of dynamic tectonic processes that shape the landscape and have an impact on human society. Tectonic geomorphology is the part of active tectonics that is concerned with landforms produced by tectonic processes and the application of geomorphic principles to tectonic problems. Tectonic geomorphology increasingly has become one of the principal tools in a variety of applications, including identification of active faults, formation of geologic structures, seismic-hazard assessment, and the study of landscape evolution. Tectonic geomorphology has proven to be useful in these applications because tectonically produced landforms are created and preserved over time intervals ideal for recording landscape change. <...>
