Judge Fahy, was appointed Special Master by the United States Supreme Court in the case of Utah vs United States (406 US 484) after the original Special Master, Judge J. Cullen Ganey, died. By coincidence, within a few weeks after Fahy's decision, the lake had risen to the 4,201 foot level. Importance of the contested shorelands became obvious during the 1960's. Development of mineral resources contained in the lake brines was held up because clear title to land needed for construction of evaporation ponds and refining plants could not be obtained. As a result, Congress passed an act on June 3, 1966, requiring the Secretary of the Interior to quitclaim to the state of Utah all United States interest in lands lying below the meander line of the Great Salt Lake excepting the Bear River Migratory Bird Refuge and the Weber Basin federal reclamation project. To effect this, Congress directed the Secretary to complete, within six months, \"the public land survey around the Great Salt Lake in the state of Utah by closing the meander line of that lake, following as accurately as possible the mean high water mark of the Great Salt Lake used in fixing the meander line on either side of the unsurveyed area\".","PeriodicalId":398645,"journal":{"name":"Utah Geology","volume":"180 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133600911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zartman","doi":"10.34191/ug-5-1_1","DOIUrl":"https://doi.org/10.34191/ug-5-1_1","url":null,"abstract":"A multistage model is presented to account for the different lead isotopic compositons of the northern and southern parts of the Gold Hill stock. The stock was found actually to be two bodies of different ages - Oligocene in the north (38 m. y.) and Jurassic in the south (152 m.y.). Initial 87 Sri 86 Sr ratios computed from measurements made on the intrusive rocks are 0.715 ± 0.001 for the north and 0.709 ± 0.001 for the south. Lead in the northern intrusion at Gold Hill and 100 km eastwards in the Oquirrh Mountains region is shown by the model to have originated in an Archean upper crustal environment (determined 11 =238U1204Pb ;::;::: 12) from 2.7 b.y. to 1.65 b.y. ago. Subsequently, this lead was incorporated in 1.65 b.y. lower crust and subjected to granulite or higher rank metamorphism (determined 11 ;::;::: 4 to 7), and remained there until being remobilized in the Oligocene by plutonic activity. The ore and feldspar lead in the southern intrusion at Gold Hill, however, seems to have remained in upper crustal environments (11 ;::;::: 12) continuously since 2.7 b.y. ago (e.g., there was no high rank metamorphism of this material in the Precambrian) until being remobilized in Jurassic time. By implication, this must apply to much of the miogeosynclinal material of similar lead isotopic composition found westwards in Nevada.","PeriodicalId":398645,"journal":{"name":"Utah Geology","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121248346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
