Precambrian schists and gneisses are exposed in much of the Ruby Mountains of southwestern Montana. The major rock types include abundant quartz-feldspar gneiss, hornblende gneiss, amphibolite, quartzitic gneiss, and marble. Minor rock types important in the study area include anthophyllite gneiss, hornblende-pyroxene-plagioclase gneiss, quartz-hypersthene-garnet granulite, iron-formation, and hornblende-hypersthene granulite. These rocks form a concordant series folded into a broad, open antiform-synform pair in the study area.This volume is a revised edition containing the complete original text plus the addition of a number of appendices. These include all maps, data tables, field notes and petrographic descriptions. I have included a new structural analysis treating the area as a single domain with all 342 strike and dip measurements, and a structure cross-section cartoon and a suggested pre-metamorphic sedimentary section. These appendices allow the reader to assess the evaluation from original descriptions.

An advanced handbook for Crystal Radio intended for the serious beginner to the veteran user. This book contains project ideas and notes interspersed with technical discussions on the theoretical basis for different aspects of the radio hobby. Discussions introduce mathematical formulas and spreadsheet models to illustrate concepts from antenna/ground, resonance, diode (solid state and vacuum), capacitance, coil Q, and audio impedance matching. Basically a technical look at crystal radio from the antenna to your ear. Also included is a small catalog of crystal hookups and a fun discourse on detecting solar flares with shortwave radio.
