Book Description
From the spiky teeth of a geode containing sparkling quartz crystals, the rich browns and golds of smoky quartz and goethite needles on calcite, and the coral-like branches of plumose barite to the abstract reds and whites of polished agate cabochons, world-class mineral crystals are harvested from the rocks of the Hawkeye State. Collecting these high-quality crystals requires access to active mines, pits, and quarries, and individual collectors are rarely allowed entrance to these facilities. With information about each specimen’s type, source, size, and current location, Paul Garvin and Anthony Plaut’s Iowa Gems and Minerals in Your Pocket provides access to the glittering, gleaming world of Iowa crystals. Most, if not all, of Iowa’s gems and minerals are products of crystallization in underground cavities that filled with water containing dissolved chemicals. The famed Iowa geodes (Iowa’s state rock) are products of a complex process of replacement and cavity-filling in the Warsaw Shale. Armored by a rind of tough chalcedonic quartz, these spheroidal masses, which range up to more than a meter across, weather out of the host rock and accumulate along streams in the southeastern part of the state. During the Pleistocene Epoch, large masses of glacial ice rafted the ultra-fine-grained variety of quartz called Lake Superior agates, which had previously weathered out of their host rocks, southward into Iowa. They can be found in the gravels that have accumulated along major streams in the eastern half of the state. Iowa’s long record of mining lead, coal, gypsum, and limestone contains a rich history; the forty-seven mineral specimens inIowa Gems and Minerals in Your Pocketmake up a fascinating illustrated guide to that history. Carefully lit and photographed to reveal both maximum detail and maximum beauty, each specimen becomes a work of art.

Book Description
Following a brief description of the major components found effective in school safety programs (safety management, education, and services) and data on school accidents in Iowa, this book addresses various aspects of safety related to science instruction, emphasizing that responsibility for safety must be shared by both teacher and students. Areas discussed include: (1) legal liability (definition of pertinent terms, teacher responsibilities, and case studies); (2) eye protection; (3) safety issues and concerns in biology, chemistry and physics settings; (4) safety concerns, considerations, and measures related to field trips and associated activities, the physical plant, science facilities, student research projects, and handicapped students; and (5) accident/incident reporting systems. General and specific guidelines are provided for each of the major areas and related topics addressed. Appendices include checklists related to the areas, a chart of selected eye protectors, safety equipment (eye washes, safe pipettor, safe pipetting station, and a self-sterilizing inoculating loop), and general first-aid guidelines.

Book Description
In his carefully written text, geologist Paul Garvin has combined scientific facts about minerals with an appreciation of their history and beauty to produce a book that will appeal to scholars, collectors, and the general public. Garvin begins with a brief treatment of the origins of Iowa's minerals, moving from the oldest - with ages well in excess of a billion years - to those most recently formed. He describes the state's major mineral occurrences, providing detailed information for both specialists and amateurs, including how to obtain access to collecting sites. A history of Iowa's mineral industries complements Garvin's more technical information; this history is supplemented with stories about the Cardiff Giant (who now has his own web page), Ottumwa's Coal Palace, and the meteor falls of the late nineteenth century.

Book Description
This informative and fully illustrated volume explores the untold story of agate gemstones hidden in Kentucky’s scenic Knobs Region. With their fine grain and rich assortment of colors, agate stones are coveted by collectors and becoming rarer across the globe. Some of the most beautiful specimens in the world have been found in the rugged terrain of eastern Kentucky. In Kentucky Agate, authors Roland L. McIntosh and Warren H. Anderson reveal the beauty and diversity of this sought-after stone with hundreds of color photographs. Kentucky Agate also reveals locations where agate may be found, offering maps of the region surrounding the city of Irvine, Kentucky, including parts of Estill, Powell, Jackson, Menifee, Madison, and Lee counties. With detailed photographs revealing aspects of the rock not visible to the naked eye, this book also provides fascinating information on the history, geology, chemistry, and formation of the mineral.
