{"title":"Commercial perlite deposits of New Mexico and North America","authors":"G. S. Austin, J. Barker","doi":"10.56577/ffc-49.271","DOIUrl":"https://doi.org/10.56577/ffc-49.271","url":null,"abstract":"Perlite is weathered volcanic glass containing from 2 to 5 wt.% water. When heated to 600°800°C in 870°-1100°C furnaces, the glass softens and its water is rapidly given off as steam. The steam expands or \"pops\" the perlite into glass foam that is from 10 to 40 times the original volume and 15 lbs/ft3 or less in density. \"Onionskin\" or classical perlite is dense, gray to bluish black with concentric fractures and a pearly luster. Granular perlite is lighter weight, microvesicular, highly fractured, and white to gray. Pumiceous perlite is extremely lightweight, frothy, and white to light gray. All types are mined commercially, but granular perlite is dominant in high-volume mines. Perlite deposits are associated with rhyolitic volcanic terranes. Most are Tertiary in age because volcanic glass is relatively short lived over geologic time. The glassy, subhorizontal tops of microvesicular (i.e., permeable), high-silica lava flows are the most favorable sites for weathering into commercial perlite. Large, steep-sided, high-silica lava domes are more common than high-silica flows. However, large domes yield relatively little commercial perlite because of their complex cooling histories and the lack of access to the meteoric water that hydrates the glass during weathering. In 1997, commercial perlite was mined at a record pace of 775,000 short tons in Arizona, California, Nevada, and New Mexico, with more than 85% of the total from New Mexico. Construction uses accounted for 71 % of expanded perlite domestic sales. Filter aids accounted for 11 % , horticultural aggregate 9%, fillers 7%, and others 2%. Other North American perlite production is from, or has recently come from, Colorado, Idaho, and Texas; the Canadian province of British Columbia; and the Mexican states of Durango, Puebla, and Sonora. New operations are online, or will come online soon, in Oregon and Utah and an Idaho operation will re-open, all of which will increase supply, thus eliminating the shortages of recent years.","PeriodicalId":427403,"journal":{"name":"Las Cruces Country II","volume":"2 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":"128729185","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}

{"title":"Pliocene (Blancan) vertebrate fossils from the Camp Rice Formation near Tonuco Mountain, Dona Ana County, southern New Mexico","authors":"G. Morgan, S. Lucas, J. Estep","doi":"10.56577/ffc-49.237","DOIUrl":"https://doi.org/10.56577/ffc-49.237","url":null,"abstract":"The Tonuco Mountain local fauna is proposed as a new name for a middle Blancan (late Pliocene) vertebrate assemblage from the Cedar Hill area southeast of Tonuco Mountain in Dona Ana County, southern New Mexico. The fossils are derived from the Camp Rice Formation in the western Jornada Basin. The stratigraphic section of the Camp Rice Formation at Cedar Hill consists of about 50 m of sandstone and conglomerate, with a minor component of sandy mudstone. The Tonuco Mountain fauna is composed of 16 species, including: the mud turtle Kinosternon; the land tortoises Gopherus and Hesperotestudo; a duck; a rabbit; the badger Taxidea; the coyote-like canid Canis lepophagus; the bone-eating dog Borophagus; the horses Nannippus cf. N. peninsulatus, Equus (Dolichohippus) simplicidens, and E. scotti; the peccary Platygonus cf. P bicalcaratus; the camels Came/ops, Hemiauchenia blancoensis, and a small undescribed species of Hemiauchenia; and the gomphotheriid proboscidean Cuvieronius. Among these taxa, C. lepophagus, Borophagus, Nannippus cf. N. peninsulatus, E. simplicidens, Platygonus cf. P. bicalcaratus, and H. blancoensis are indicative of the Blancan land mammal age (between 4.5 and 2.0 Ma). Several taxa help to further limit the age of this fauna within the Blancan. E. simplicidens is absent from very early Blancan faunas, Platygonus and Came/ops do not appear until the beginning of the middle Blancan (about 3.7 Ma), and most Blancan records of Nannippus in the southwestern United States predate the Gauss-Matuyama magnetic reversal at about 2.6 Ma. The absence of South American immigrants suggests the fauna is older than 2.8 Ma, the earliest date for the onset of the Great American Fauna! Interchange. These biostratigraphic data restrict the age of the Tonuco Mountain local fauna to the middle Blancan (between 3.7 and 2.8 Ma). Previous magnetostratigraphic studies of the Camp Rice Formation at Cedar Hill help to further constrain the age of this fauna. The entire section is within the Gauss chron (younger than 3.6 Ma), and the fossiliferous interval is below the top of the Kaena subchron (older than 3.0 Ma). The presence of a carpal bone of the rhinoceros Teleoceras from the Rincon Valley Formation in the Cedar Hill area suggests a late Miocene (Hemphillian) age, which is in accordance with a radioisotopic date of 9.6 Ma on the Selden Basalt Member of the Rincon Valley Formation. 237","PeriodicalId":427403,"journal":{"name":"Las Cruces Country II","volume":"36 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":"121008657","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}
