Saudi Arabian Project Report 108: Report on the Exploration of the Wadi Yiba Copper Prospect, Tihamat Ash Sham Quadrangle, Kingdom of Saudi Arabia (SA(IR)-108)

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).…
