It is not much to document the origin of bird flight. Strictly speaking, these specimens are not the entire body of evidence. There are, of course, other fossil birds, not to mention bats, pterodactyls, and insects that have a few things to say about bird flight. And there are living creatures, mathematical models, and aerodynamic theories to help us understand this amazing evolutionary accomplishment. Nonetheless, these seven specimens are crucial. They lie at the heart of complex debates that began with the discovery of the first specimen of Archaeopteryx more than 130 years ago and continue up until today. These few, special fossils have served as the basis for brilliant deductions, wild speculations, penetrating analyses, and amazing insights. They have revealed—and continue to reveal—not only the pathway through which birds and bird flight may have originated, but they also tell us much about the strengths and weaknesses of science and scientists. <...>
This introduction chapter of the book provides a summary of its nine key chapters. Structural geology and tectonics has progressively become more quantitative. To keep the pace, instructors of these subjects need to upgrade their teaching contents. This book presents issues related to (i) evaluation system of students using the peers, (ii) use of new instruments in measuring structural data from rocks, (iii) paleomagnetic studies in tectonics, (iv) sub-surface structural interpretations required in industries, (v) field studies in structural geology, (vi) interdisciplinary aspects of structural geology, (vii) teaching structural geology and tectonics in Indian context, (viii) conducting practical classes in structural geology with map interpretations and (ix) and simple geomechanical problems and solutions. <...>

In Liberia, Mano has interests in 3 mineral licences with gold exploration activity. To date most exploration has focused on the 100,000 hectare license known as the Bea Mountain Mineral Development Agreement (BEA-MDA) in western Liberia. Mano has a 100% interest in the BEA-MDA license subject to a 10% free carried interest and a 3% royalty in favour of the Republic of Liberia. The MCA reconnaissance license (1,500,000 hectares) is held under a Mineral Cooperation Agreement (MCA) with the Republic of Liberia.

This book is a survey of techniques used in archaeological geology or as it is more widely known, today—geoarchaeology. It is less a discussion of theory or methodology with regard to the various geological techniques that are presented. It is not an exhaustive presentation of the diversity of earth science methods that can be utilized in the service of archaeology. Earth science can be used in many ways in archaeology.
The study of sediments and sedimentary rocks has come a long way from the early days Of field observations followed by a cursory examination of samples in the laboratory. Now many sophisticated techniques are applied to data collected in the field and to specimens back in the laboratory. Some of these techniques have been brought in from other branches of the earth sciences, while some have been specifically developed by sedimentologists.
Тектонический контроль, реконструкция и консервация тигелонгнанского месторождения порфиров и эпитермальных отложений меди (Au), Центральный Тибет, Китай
The newly discovered Tiegelongnan Cu (Au) deposit is a giant porphyry deposit overprinted by a high-sulfidation epithermal deposit in the western part of the Bangong–Nujiang metallogenic belt, Duolong district, central Tibet. It is mainly controlled by the tectonic movement of the Bangong–Nujiang Oceanic Plate (post-subduction extension). After the closure of the Bangong–Nujiang Ocean, porphyry intrusions emplaced at around 121 Ma in the Tiegelongnan area, which might be the result of continental crust thickening and the collision of Qiangtang and Lhasa terranes, based on the crustal radiogenic isotopic signature.
Cenozoic, mafic alkaline volcanic rocks throughout West Antarctica (WA) occupy diverse tectonic environments. On the Antarctic Peninsula (AP), late Miocene Pleistocene (7 to < 1 Ma) alkaline basaltic rocks were erupted < 1 to 45 million years after subduction ceased along the Pacific margin of the AP. In Marie Byrd Land (MBL), by contrast, alkaline basaltic volcanism has been semi-continuous from 25-30 Ma to the present, and occurs in the West Antarctic rift system. Together, these Antarctic tectono-magmatic associations are analogous to the Basin and Range, Sierran, and Coast Range batholith provinces.
