In the Java sea Tertiary sediments cover a cratonized basement of pretertiary age. Tentative standard sections of the Tertiery sequence employ used stratigraphic nomenclature. Regional lithologic correlation provides a consistenst picture of alternating carbonate and clastic series covered by a clay series. This corelations is substantiated by paleo…
The relevant characteristic of the evolution of the Pacific continental margin of South America during the Mesozoic-Early Cenozoic has been tectonic segmentation. This has controlled succesive episodes of sedimentary accumula, Ition, extrusive and intrusive magmatism and deformation that ocurred at conververgent plate edges. …
An aapa mire was investigated peat geologically. Based on about 1500 volumentric peat samples, the depth, peat types, degree of decomposition (V. Post's methods), bulk density, water content and shear strength were examined along an 800 m transcet. The calorific value was determined from 58 respresentative peat samples from the same transect, as wel…
Marine technology is a complex science and Indonesia, needs a realistic strategy for the implementation of the relevant technology. The strategy should be evolutionary and should coincide with a national marine program, and with current prevailing domestic and international conditions. There is no doubt that present day practitioners will influence …
Over the past several decades the philosophy of exploration for oil and gas has pro• gressively changed from drilling on surface seepages to the concept of structural traps, com• plemented later by considerations of sedimentology in relation to the development of reser• voirs, which led to the concept of stratigraphic traps. …
In the past, conventional reflection seismic techniques were not very successful when applied to typical mining exploration:They lacked resolution in the shallow range or were not cost effective. By combining a light earth tamper source, special geophones and field procedures, a stacking process of the returning seismic events using a microprocessor…
Daerah Selogiri, yang terletak di Kabupaten Wonogiri, Jawa Tengah, adalah salah satu dari beberapa daerah pencarian emas di Daerah selatan Pegunungan di Jawa, Indonesia. Tiga jenis batuan intrusi dioritik-andesitik terjadi di daerah Selogiri, yaitu, porfiri andesit hornblende, porfirior hornblende diorite dan hornblende diorite, terekspos dalam depr…
Electrical consumption in Indonesia, especially in the back country such as District Ende, Flores - Nusa Tengara Timur, is rising as well as its physical and infrastructure development, and its community standard of living. Therefore, the electrical consumption of PT. PLN (Persero) of XI Region, especially PT. PLN (Persero) of Ende, Flor…
