Paperback. Condizione: New. Print on Demand. This book explores the mineral resources of the Scapegoat Wilderness, an area of stunning rugged terrain in Montana. The result of a comprehensive survey by the U.S. Geological Survey and the U.S. Bureau of Mines, the book offers valuable information on the area's mineral wealth, stratigraphy, structure, and geologic history. It discusses various rock formations, ranging from Precambrian to Paleozoic, and describes the complex interplay of thrust and normal faults, folds, and igneous intrusions that shaped the region's geology. Providing geochemical data and detailed maps, the book assesses the economic potential of different mineral deposits, particularly copper, and provides insights into the area's mining history. The book concludes by emphasizing the importance of mineral resource evaluation in land management and conservation efforts, highlighting the delicate balance between resource extraction and environmental preservation. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.

Soft cover. Condizione: Good. 1st Edition. Original green printed wraps with green cloth spine 22x28cm. (2)pp prelims including covering letter from Glen Brown to Fadil Kabbani, Deputy Minister for Mineral Resources, iii pp Contents, 42pp including maps and tables printed to the rectos only, with 3 folding sheets (Figs 1, 9, 10) present in the pocket at the end complete as called for. It is noted that there is no p29 and no indication of anything missing (the text on p30 is a continuation of the discussion on p28), and there are two p35s, one of which is numbered p35a. Wraps good with loss to spine cloth, and 2 perforations to the lower wrap. Interiors very good with ink offsetting to the blank versos (not affecting text), and sheets neatly folded. This report is an early "preliminary" product of the monumental USGS-Aramco mapping project (1956-63), which, among other things, produced 21 Geological maps covering the whole of Saudi Arabia in a series of Quadrangles numbered I-200A to I-220A. It was prepared under the follow-up Saudi Arabian Mineral Exploration Project launched in 1963, which Brown coordinated from Jeddah. The area covered lies within the Tihamat Ash-Sham Quadrangle (covered by Map I-216A), accessible by unpaved roads from Jeddah in the north and Jizan in the south, and two airstrips suitable for bush aircraft. This presents the results of fieldwork done during November 1967 to April 1968 that involved geological mapping, prospecting, sampling, helicopter borne geophysical surveys, and diamond drilling. It recommends further exploration to assess potential. One of the folding sheets is a "Geologic Map of the Wadi Yiba copper prospect", 1/20K, 31x48cm. Among the limited number of references cited are Map I-216A, and Technical Letters No. 96 by Davis and Akhrass, and 97 by Earhart (both 1967). Very rare. Brown's covering letter states 20 copies were sent to Kabbani. Additional copies would have been circulated within USGS and probably Aramco. Worldcat locates copies at 3 USGS libraries (Reston, Denver, and Menlo Park), and one at the South Dakota School of Mines & Technology (OCLC 22696262).

The area covered lies within the Tihamat Ash-Sham Quadrangle (covered by Map I-216A), accessible by an unpaved road from Jeddah, with an airstrip suitable for bush aircraft. Fieldwork was conducted during November 1967 by Ghanem Geri, a prospector-guide employed by USGS, who discovered copper in Jebel Sarbon. He was then joined by the author and AE Weissenborn of USGS to examine the discovery further. The first map, 1/1M, locates the area in relation to the Red Sea coast showing unpaved roads, major wadis, towns, and ancient mines. The second, 1:600, shows the location of samples and analytic results in the southern part of Jabal Sarbon. Very rare. Brown's covering letter states 20 copies were sent to Kabbani. Additional copies would have been circulated within USGS and probably Aramco. Worldcat locates only one at the Colorado School of Mines (OCLC 182624810). USGS reissued it in 1969 as Open-File Report 69-81 (USGS website).

Soft cover. Condizione: Good. 1st Edition. Original staple-bound green printed wraps with green cloth spine 22x28cm. (2)pp prelims including covering letter from Glen Brown to Fadil Kabbani, Deputy Minister for Mineral Resources, ii pp Contents, 46pp text including 1 folding sheet + 1 full-page Index Map printed to the rectos only, with 2 very large folding maps in pocket (Figs 4 and 5), complete, with both present as called for. Wraps good, tanned towards the edges, with tears and minor loss to the spine cloth, and tears at the staples at the back. Interiors very good with ink offsetting to the blank versos (not affecting text). Loose maps neatly folded, yellowed at edges and folds. This report is an early "preliminary" product of the monumental USGS-Aramco mapping project (1956-63), which, among other things, produced 21 Geological maps covering the whole of Saudi Arabia in a series of Quadrangles numbered I-200A to I-220A. It was prepared under the follow-up Saudi Arabian Mineral Exploration Project launched in 1963, which Brown coordinated from Jeddah. The area, named after the Red Sea port of Al Qunfidhah, the largest settlement within it, lies within the Tihamat Ash-Sham Quadrangle (covered by Map I-216A). For the investigation, this was divided into the areas around Al Khamis, and the Wadi Yiba copper prospect. Work started with a helicopter survey looking for sulphides and precious metals during February to June 1967. Field operations were conducted from a camp and an airstrip near the village of Suq al Khamis using 2 G-2 Bell helicopters, and serviced by Otter and Beaver aircraft from Jeddah. The roads were unpaved. The area was sparsely populated primarily with Bedouin sheep and goat herders. MAPS: Fig 4: Geological Reconnaissance Map of the Suq al Khamis Area, 1/64K, blue line drawing, 90x96cm. Fig 5: Geological Map of the Wadi Yiba Copper Prospect, 1/10K, blueline drawing, 82x100cm. These show wadis, sample locations, and geological features; a geological explanation; analysis data tables; and Location ("Index") Maps, one of which 1/5K showing the area in relation to Al Qunfidhah, Al Khamis, the ancient mine at Al Muckahal, etc. Very rare. Brown's covering letter states 20 copies were sent to Kabbani. Additional copies would have been circulated within USGS and probably Aramco. Worldcat records other letters in the series, but not this one. USGS reissued it in 1969 as Open-File Report 69-82 (USGS website).

Soft cover. Condizione: Good. 1st Edition. Original green printed wraps with green cloth spine 22x28cm. (2)pp prelims including covering letter from James Norton to Fadil Kabbani, Deputy Minister for Mineral Resources, v pp Contents; 100pp including 2 folding maps, 3 full-page maps, and 5 full-page cross-sections; complete with 6 large b/w loose folding Plates (Geologic Maps) in pocket all present as called for. It is noted that Table 4 is numbered twice (p18 and p19), and there is no p22 although the text from p20 to p23 appears to be continuous. Wraps good with much loss to spine cloth, and some strain to the lower wrap owing to the thickness of the folded Plates. Interiors mostly very good with ink offsetting to the blank versos (not affecting text), red ink annotations to 3 of the cross-sections (pp71, 78, 80), and sheets neatly folded. The covering letter is ink stamped "Library" in English and Arabic, with no indication of the institution, and no other such marks. This report is an early "preliminary" product of the monumental USGS-Aramco mapping project (1956-63), which, among other things, produced 21 Geological maps covering the whole of Saudi Arabia in a series of Quadrangles numbered I-200A to I-220A. It was prepared under the follow-up Saudi Arabian Mineral Exploration Project launched in 1963, which was initially coordinated from Jeddah by Glen Brown, with James Norton taking over in 1969. The area covered lies within the Southern Hijaz Quadrangle (covered by Map I-210A), containing 5 ancient mines, and accessible by unpaved road from Taif and an airstrip suitable for light aircraft. The aim of this report was to evaluate their mineral potential, locate target areas, and identify lessons for other areas in Saudi Arabia with similar geologic conditions. The author noted current land use consisted of sheep and goat grazing, small pomegranate and apricot orchards, millet fields, a few grapes and lemons. The area is sparsely populated with settlers and a few nomads. The large number of ruined fortresses may be Ottoman, suggesting a far greater population at that time. There are also Abbasid era ruins in less accessible areas near ancient mines, the best preserved of which at Mulgatah and Mulhal. Wildlife includes fox, wolf, rabbits, baboons, birds, rodents, reptiles and insects including the anopheles mosquito. The fieldwork was done by GH Allcott and RL Earhart during Spring and Summer 1967, including mapping, geochemical and geophysical studies. This resulted in the location of numerous mineralised localities, and visits to known localities. The folding Plates include Geologic Maps of (1)Wadi Bidah District, 1cm to 500 metres, 45x98cm; and the localities of the 5 ancient mines, each on a large 1cm to 10 metres scale at: (2) Mulgatah, 36x65cm; (3) Gehab, 55x99cm; (4) Aha'ab Eltare, 45x80cm; (5) Muhal, 45x69cm; and (6) Rabathan, 54x98cm. Their relative locations are shown by the Index Map in the report on p4. Very rare. Norton's covering letter states 50 copies were sent to Kabbani. Additional copies would have been circulated within USGS and probably Aramco. Worldcat locates copies at 2 USGS libraries (Reston, Denver), and one at the Colorado School of Mines (OCLC 39915064).
