Dolomit merupakan salah satu variasi dari batugamping dengan komposisi kimia CaMg(CaC03)2 atau berupa manganodolomit MnFe(CaC03)2 atau ferrodolomit yang berkomposisi MgFe(CaC03}2. Batuan . ini merupakan Batugamping yang sebagian dari unsur kalsiumnya diganti oleh magnesium. Batuan ini merupakan bahan baku penting yang d…
The rise of air temperatures near Earth's surface over the past century is known as global warming. Earth has experienced periods of gradual wanning and cooling throughout its existence due to natural causes, such as volcanic eruptions and variations in the un 's output. However, scientists have attributed …
A direct means of indicating the presence of concealed mineralization would be the ultimate in exploration. In many ways the.induced-polarization (IP) technique comes close to achieving this goal. it has been remarkably successful in locating concealed bodies containing even small percentages of metallic-luster minerals.

When I put pen to paper in the summer of 1982, uppermost in my mind was the need to provide new practitioners with an introduction to the theory and practice of thermoluminescence (TL) dating, particularly those without a strong background in physics. Assimilating the corpus of specialist papers which at present define the theory and practi…
This practical step by step guide describes the key geological field techniques needed by today's exploration geologists involved in the search for metallic mineral deposits. The techniques described are fundamentals to the collection, storage and presentation of geological data and their use to locate ore. This book explains the various tasks which…
Each year approximately 40 million metric tons of processed kaolin are sold around the world into markets ranging from brick making to paper coating. This functional versatility is a direct consequence of natural variability in deposit quality, which is controlled by mineralogy and processing. Poorer quality deposits, which contain relatively large …
A century has passed since the first X-ray diffraction experiment (Friedrich et al.1912). During this time, X-ray diffraction has become a commonly .used technique for the identification and characterization of materials and the field has seen continuous development. Advances in the theory ofdiffraction, in the generation o…
Archaeological geophysics is not the kind of research one can do alone. Every project I have worked on, whether field research, data processing, or software development, has involved someone in a crucial capacity towhom.I owe a great deal. My great thanks go to Ieffrey Lucius at the U.S. Geological Survey in Denver, Colorado, who first held my…
Central Indonesia consists of an assortment of micro continents amidst micro- oceanic plates. The map in Fig. 2.0-1 is based mainly on interpretation of various authors, checked for accuracy by bathymetric, Bouger gravity, and surface geology maps as well .. Deep sea basins are generally underlain by an oceanic crust. This is supported by …
AN elementary textbook is much concerned with the fundamentals of a subject and these do not change with time. In this respect the second edition of our book •has been little modified. In every other it is much altered for the subject has advanced greatly since we gathered together the material for the original version. The changes have…
