This book provides a very basic introduction to electron microscopy and energy dispersive spectrometry (EDS). It has the largest compiled collection of EDS spectra ever published and covers most common rock forming minerals. In addition, it provides a key to help the novice wade through the large number of spectra.

Scientific notes and summaries of investigations in geology, hydrology, and related fields.

This textbook presents the principles and methods for the measurement of radioactivity in the environment. In this regard, specific low-level radiation counting and spectrometry or mass spectrometry techniques are discussed, including sources, distribution, levels and dynamics of radioactivity in nature. The author gives an accurate description of the fundamental concepts and laws of radioactivity as well as the different types of detectors and mass spectrometers needed for detection. Special attention is paid to scintillators, semiconductor detectors, and gas ionization detectors. In order to explain radiochemistry, some concepts about chemical separations are introduced as well. The book is meant for graduate and advanced undergraduate students in physics, chemistry or engineering oriented to environmental sciences, and to other disciplines where monitoring of the environment and its management is of great interest.

Excavated in 2009, An Son, Long An Province, southern Vietnam has been dated to the second millennium BC, with evidence for neolithic occupation and burials. Very little is known about the neolithic period in southern Vietnam, and the routes and chronology for the appearance of cultivation, domestic animals, and ceramic and lithic technologies associated with sedentary settlements in mainland Southeast Asia are still debated. The ways in which the ceramic material culture at An Son conforms to the wider neolithic expression observed in Southeast Asia is investigated, and local and regional innovations are identified. The An Son ceramic assemblage is discussed in great detail to characterise the neolithic occupation, while considering the nature of craft production, manufacturing methods and the transference of traditions. Contextualising the neolithic in southern Vietnam is conducted through a comparative study of material culture between An Son and the sites of B?n Ðò, Bình ?a, Cù Lao Rùa, Cái V?n, C?u S?t, ?a Kai, ?ình Ông, L?c Giang, R?ch Lá, R?ch Núi and Su?i Linh, all in southern Vietnam. Another analysis is presented to contextualise An Son in the wider neolithic landscape of mainland Southeast Asia, between An Son and Ban Non Wat, early Ban Lum Khao, early Ban Chiang, early Non Nok Tha, Khok Charoen, Tha Kae, Khok Phanom Di, Nong Nor (phase 1), Samrong Sen, Laang Spean, Krek, Bàu Tró, Mán B?c and Xóm R?n. The aspects of material culture at An Son that appear to have ancestral links are considered in this research as well as local interaction spheres.

This volume deals with sulphates, carbonates, phosphates and halides, incorporating recent advances in investigative techniques. Each mineral chapter has sections on structure, chemistry, optical and physical properties, distinguishing features and paragenesis. Chapters are headed with brief tabulations of mineral data and a sketch of optical orientation. Results are included from ocean floor experimentation and deep sea drilling.
