The best mineral potential appears .to be in the Ad Dawadami district, where silver and lead were formerly mined, and in the southwestern part of the quadrangle in the vicinity of the Nafud al Urayk. Ancient mines in the southwestern part of the quadrangle were probably opened for gold, but the present exploration disclosed tungsten and antimony minerals, and slightly anomalous lead, zinc, and molybdenum. Of these elements the greatest potential appears to be tungsten. \r\n\r\nMost ancient mines and the newly discovered mineralized veins are in areas underlain by graywacke intruded by granitic stocks and apophyses. These areas should be further investigated for ore deposits.","language":"ENGLISH","publisher":"U.S. Geological Survey],","doi":"10.3133/ofr70240","usgsCitation":"Mytton, J.W., 1970, Reconnaissance for mineral deposits in the Precambrian rocks of the Wadi Ar Rimah quadrangle, Kingdom of Saudi Arabia: U.S. Geological Survey Open-File Report 70-240, 76 p. ill., maps (some col.) ;28 cm., https://doi.org/10.3133/ofr70240.","productDescription":"76 p. ill., maps (some col.) ;28 cm.","costCenters":[],"links":[{"id":148276,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1970/0240/report-thumb.jpg"},{"id":44050,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1970/0240/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":44051,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1970/0240/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a55e4b07f02db62c98e","contributors":{"authors":[{"text":"Mytton, James W.","contributorId":44147,"corporation":false,"usgs":true,"family":"Mytton","given":"James","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":170620,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

These values were computed using: (1) Terzaghi's bearing capacity equations for circular footings, (2) Meyerhof's dimensionless numbers for general shear on level surfaces, (3) a cohesion of 10<sup>3</sup> dynes per cm<sup>2</sup>, (4) a density of 1.35 gm per cm<sup>3</sup> for the near surface materials, (5) a density of 2.7 gm per cm<sup>3</sup> for the block or boulder, (6) spheroidal (triaxial) boulders unless definite shapes can be established, (7) footing radii equal to the half-width of the block or boulder, the half-width of the track, and(or) the half-width of the shadow near the base of the block or boulder.</p><p>For 115 secondary impact craters and their corresponding blocks, dynamic strengths are estimated using: (1) the product of one-half the mass per unit area of the block and the normal component of velocity squared divided by the crater depth, and (2) the ratio of the kinetic energy of the block and the volume of the secondary crater. Velocities of the blocks are calculated using a ballistics equation and assuming an ejection angle of 45°. Block densities are taken as 2.7 gm per cm<sup>3</sup>. Dynamic strengths of the near surface materials using the first procedure average 25.2 x 10<sup>5</sup> dynes per cm<sup>2</sup> (37 psi); and, for the second procedure, they average 19.2 x 10<sup>5</sup> dynes per cm<sup>2</sup> (28 psi). Comparison between dynamic strengths and expected static strengths, computed for each block using the assumptions above, show that most of the dynamic strengths correspond to the static strengths when the friction angle is 30° and larger.&nbsp;</p><p>Data on experimental low velocity impacts with natural targets are compared with the lunar data on secondary impacts. Nara's modified Poncelet equation for sand yields an average angle of internal friction near 34° using the appropriate block and soil constants mentioned above.&nbsp;</p><p>Comparison of coefficients computed using the equations for sand of Clark and McCarty, Mortensen, and Moore for the lunar data with the corresponding constants for terrestrial data indicate the lunar coefficients are generally low.
