Bahan galian industri adalah mineral industri dan batuan, yaitu semua bahan galian di luar mineral logam dan radioaktif yang mempunyai kegunaan langsung untuk berbagai industri. Menurut undang-undang dan peraturan yang berlaku ten tang penggolongan bahan galian (PP No. 27/1980), maka sebagian besar bahan galian industri termasuk bahan galian Golongan C. Secara geologi bahan g…
Geodynamics, the study of global movements and of the forces driving them, is a rekatively fresh offshoot from the vigorously branching tree of the earth sciences. Before the advent of Alfred Wegener on this scene in the early nineteen-hundreds, the idea of permanency in the distribution of continents and oceans was almost sacrosanct.
Das Antlitz der Erde, or “The Face of the Earth”, was the title of the first great magnum opus on the gross surface features of the earth by Eduard Suess late last century. A recent British television documentary with the same purpose bore the same title.
rectangular area of 72,000 ha along the tidal reach of the Batanghari River, northeast of Jambi, Sumatra, has been proposed by the Indonesian government as one of the sites for developing a community to relieve the population pressure in other parts of Indonesia (see figure l). By year 2000, Hanson and Koesoebiono (1975) estimated that a population of perhaps 250 million people would requir…
The impetus for publishing this set of articles was the realization that, year after year. I and my students at Stanford were making copies (with varying degrees of legibility and legality) of the same classic articles on plate tectonics and geomagnetic reversals. At first we did this because there was so little material on the subject available.
lmu Petrografi batubara sebetulnya telah dipelajaari sejak awal abad ke 20 yang dipelopori oleh Marie Stopes, (1919) dan Reinhardt Thiessen, (1920). Kedua nama ini telah memperkenalkan terminologi dan klasifikasi batubara yang sampai saat ini masih terpakai. Namun penclitian batubara secara petrografi baru dimulai sejak tahun 1930-an, dimana Marie Stopes, (1930) memp…
The tectonic concept known as seafloor spreading , global tectonics and also as plate tectonics began engulfing the geological community in the early sixties. Within less than a decade this unifying, geotectonic hypothesis beame widely known, and judging from the current literature, it has also been widely accepted.
The monograph Geothermal Resources: An Energy Alternative by Harsh K. Gupta presents for the first time a readable, coherent account of all facets of geothermal energy development. The development of alternative, renewable energy resources during the past decade has been spurred by a crunch in the supplies of traditional hydrocarbon energy resources, which have previously been inexpensive and r…
This book is based at the level of a bachelor’s degree in physical science. Experience at Standford indicate that a one-semester class in engineering systems theory provides helpful additional background. It will be readable to a general science and engineering audience and should be useful to anyone interested in computer modelling and data analysis in physical sciences.
