Centennial History of the Carnegie Institution of Washington: Volume 3, The Geophysical Laboratory


Book Description

For over a century, the Geophysical Laboratory of the Carnegie Institution of Washington has witnessed exciting discoveries and ingenious research, made possible by the scientific freedom granted to members of the department. For the most part, this research has involved laboratory experimentation on the physics and chemistry of rock-forming minerals at high temperature and pressure. This third volume in a series of five histories of the Carnegie Institution documents the contribution made by the members of the Geophysical Laboratory to our understanding of the Earth, from mineral formation deep below the surface, to the search for the origins of life, and out into space to study the chemical evolution of the interstellar medium. Field work has taken researchers from active volcanoes to ships collecting ocean sediments, and geological mapping expeditions around the world. Contemporary photographs throughout illustrate the evolution of the department and its research.







The Ore Minerals and Their Intergrowths


Book Description

The Ore Minerals and Their Intergrowths focuses on the properties, characteristics, and reactions of ore minerals. The book first offers information on genetic systematics of ore deposits and ore textures. Discussions focus on meteorites, magmatic, sedimentary, and metamorphic sequences, fabric properties considered from a purely geometric point of view, genetic fabric types, and the relationship of ore textures with industrial minerals. The text then elaborates on annotation concerning the arrangement of materials and elements and intermetallic compounds. The publication takes a look at alloy-like compounds and tellurides and common sulfides and "sulfosalts". Topics include umangite, bornite, jalpaite, argentite, naumannite, crookesite, coloradoite, novakite, orcelite, maucherite, parkerite, and horsfordite. The manuscript further touches on oxide ore minerals and gangue minerals and non-opaque oxide ore minerals, including quartz, calcite, dolomite, siderite, cerussite, smithsonite, jarosite, tenorite, zincite, and cuprite. The text is a dependable reference for readers interested in ore minerals and their intergrowths.
