Sommario/riassunto |
|
Owls are enduringly popular birds, but due to their nocturnal habits most species are difficult to see well. The plumages of many species are cryptic and difficult to separate by plumage alone. This problem is compounded by the different morphs that many adopt. This book fully describes every known species and subspecies of owl, as well as presenting the latest evidence on owl taxonomy, based on DNA work and vocalisations. Because voice is vital in owl identification, much |

"With a section on Potassium-argon and p40sAr/p39sAr geochronology of selected plutons in the Buckingham area, by Edwin H. McKee and a section on Economic geology, by Thomas A. Loucks and Craig A. Johnson and a section on Supergene copper deposits at Copper Basin, by David W. Blake and a section on -- Mineral chemistry of Late Cretaceous and Tertiary skarns, by Jane M. Hammarstrom." |
"The Buckingham stockwork molybdenum deposit, a Late Cretaceous calc-alkaline system, is estimated to contain more than 1,000 million tons of mineralized rock averaging 0.10 weight percent Mo (MoS2) and containing small amounts of silver, tungsten, copper, and gold." |
