This book was released on 2020 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Nikolai electromagnetic and magnetic airborne geophysical survey is located in interior Alaska in the Delta River mining district, about 200 kilometers southeast of Fairbanks. Frequency domain electromagnetic and magnetic data were collected with the Aerodat Condor system in 1995. A total of 3412.8 line kilometers were collected covering 660.1 square kilometers. Line spacing was 200 meters (m). Data were collected on a helicopter towed sensor platform ("bird") on a 30 m long line. The electromagnetic equipment recorded data slightly above 30 m above ground level (AGL), and the magnetometer recorded data slightly above 45 m AGL due to safety considerations. The Nikolai data were provided to DGGS by the U.S. Department of Interior Bureau of Land Management (BLM) and were merged with the Southern Delta River survey (2002) as a contract deliverable. The 2003 release of the Southern Delta River survey included map sheets of the merged data.

This book was released on 2020 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Hetta geophysical survey is located in southeast Alaska in the Ketchikan area, about 350 kilometers south of Juneau, Alaska. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system in May 1992. A total of 1,707 line kilometers were collected covering 323.3 square kilometers. Line spacing was 200 meters (m). Data were collected approximately 30 m above the ground cover or tree canopy from a helicopter-towed sensor platform ("bird") on a 30-m-long line. The large trees and steep terrain resulted in an average ground clearance of 150 m. The Hetta survey was flown for the American Copper & Nickel Company, Inc. and provided to DGGS by the Sealaska Corporation. The data were merged and released with the 1999 Ketchikan geophysical survey maps. Map sheets and some of the other files in this data release contain data from adjacent or nearby surveys.

Download or read book A New Approach to Interpretation of Airborne Magnetic and Electromagnetic Data written by and published by . This book was released on 1996 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The airborne geophysical survey carried out at the Oak Ridge Reservation has shown that AEM can be used in evaluating details of waste areas. However, detection of small objects requires a flight altitude of 10-15 m which is impossible due to natural obstacles present in the Oak Ridge area. In these types of cases, data processing in the downward continuation allows to improve the survey resolution and a normalized gradient provides an additional information about the depth of buried objects.

Download or read book INTERPRETATION OF AIRBORNE ELECTROMAGNETIC AND MAGNETIC DATA IN THE 600 AREA. written by and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of the 200-PO-1 Phase I geophysical surveys, Fugro Airborne Surveys was contracted to collect airborne electromagnetic (EM) and magnetic surveys of the Hanford Site 600 Area. Two helicopter survey systems were used with the HeliGEOTEM{reg_sign} time domain portion flown between June 19th and June 20th, 2008, and the RESOLVE{reg_sign} frequency domain portion was flown from June 29th to July 1st, 2008. Magnetic data were acquired contemporaneously with the electromagnetic surveys using a total-field cesium vapor magnetometer. Approximately 925 line kilometers (km) were flown using the HeliGEOTEM{reg_sign} II system and 412 line kilometers were flown using the RESOLVE{reg_sign} system. The HeliGEOTEM system has an effective penetration of roughly 250 meters into the ground and the RESOLVE system has an effective penetration of roughly 60 meters. Acquisition parameters and preliminary results are provided in SGW-39674, Airborne Electromagnetic Survey Report, 200-PO-1 Groundwater Operable Unit, 600 Area, Hanford Site. Airborne data are interpreted in this report in an attempt to identify areas of likely preferential groundwater flow within the aquifer system based on the presence of paleochannels or fault zones. The premise for the interpretation is that coarser-grained intervals have filled in scour channels created by episodic catastrophic flood events during the late Pleistocene. The interpretation strategy used the magnetic field anomaly data and existing bedrock maps to identify likely fault or lineament zones. Combined analysis of the magnetic, 60-Hz noise monitor, and flight-altitude (radar) data were used to identify zones where EM response is more likely due to cultural interference and or bedrock structures. Cross-sectional and map view presentations of the EM data were used to identify more electrically resistive zones that likely correlate with coarser-grained intervals. The resulting interpretation identifies one major northwest-southeast trending preferential flowpath with several minor units running along a similar trend. This presumed path of preferential flow is compared with the tritium concentration levels observed for the 600 Area. Analysis of the magnetic field data shows the location of potential bedrock faults and lineaments which may influence the horizontal and vertical flow of water. Faults lying within, or in the vicinity of preferential groundwater flow paths may allow flow into or out of the otherwise confined basalt layers.

Book Synopsis The Geology of Egypt by : Zakaria Hamimi
Download or read book The Geology of Egypt written by Zakaria Hamimi and published by Springer Nature. This book was released on 2019-09-19 with total page 711 pages. Available in PDF, EPUB and Kindle. Book excerpt: This richly illustrated book offers a concise overview of the geology of Egypt in the context of the geology of the Arab Region and Northeast Africa. An introductory chapter on history of geological research in Egypt sheds much light on the stages before and after the establishment of Egyptian Geological Survey (the second oldest geological survey worldwide), Hume's book and Said's 1962, 1990 books. The book starts with the Precambrian geology of Egypt, in terms of lithostratigraphy and classifications, structural and tectonic framework, crustal evolution and metamorphic belts. A dedicated chapter discusses the Paleozoic-Mesozoic-Cenozoic tectonics and structural evolution of Egypt. A chapter highlights the Red Sea tectonics and the Gulf of Suez and Gulf of Aqaba Rifts. Subsequent chapters address the Phanerozoic geology from Paleozoic to Quaternary. The Egyptian Impact Crater(s) and Meteorites are dealt with in a separate chapter. The Earth resources in Egypt, including metallic and non-metallic ore deposits, hydrocarbon and water resources, are given much more attention throughout four chapters. The last chapter addresses the seismicity, seismotectonics and neotectonics of Egypt.
