In den WarenkorbSoft cover. Zustand: Good. 1st Edition. Two related reports in original staple-bound brown printed wraps 22x28cm. TL 58: (1), 17; TL63: (1), 8pp, both opening with a covering letter from Glen Brown to Fadil Kabbani, Deputy Minister for Mineral Resources. Wraps good, foxed and faintly damp stained, short closed tears, staples rus…ting. Interiors near fine with red ms ticks by the edge of the table on p6 in TL53, and some ink offsetting to the blank versos (not affecting text). These reports are a very 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. They were prepared under the follow-up Saudi Arabian Mineral Exploration Project launched in 1963, which Brown coordinated from Jeddah. The team was made up of staff from USGS and the Directorate General for Mineral Resources. Their first analysis done during 22 March and 9 May was issued on 15 May 1966, based on 31 samples collected from Wadi Wassat in the Asir area (Map I-217A Asir Quadrangle). They found potential sources for pyrite meriting further exploration. Progress Report II issued on 8 June, presents findings with respect to silver and gold deposits. Among the main references are Overstreet's own Technical Letters 23 and 40. Very rare. Brown's covering letter states 10 copies of each 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 them in 1967 as Open-File Reports 67-174 and 67-175 (USGS website).
