Jadi pada hakekatnya cebakan mineral itu merupakan anomali dalam kadar berbagai unsur, dan keadaan anomali-anomali itu sebenarnya adalah sesuatu keadaan yang sangat langka dalam kerak bumi ini. Anomali ini disebabkan beroperasinya proses• proses geologi di dalam maupun dipermukaan kerakbumi dalam keadaan yang …
As MA y be divined from its title, this book is about mining geology. Less evident, perhaps, is the fact that it seeks to cover a field rather different from that of texts entitled Mineral Deposits or Economic Geology. Those texts, concerned primarily with the origin and nature of mineral deposits and with descrip…
Infrared and nonresonant Raman spectroscopies are based on the excitation of specific vibrational modes of the system under study. The frequency, intensity and width of the measured signals are highly sensitive to the local structure, composition and microstructure of the investigated samples, leading to a wide range of applications in mineralogy …
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…
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…
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 …
