Show Utah Acedetruj of Sciences, Arts and Letters 16 one fault, referred to here as the East Bench Fault, 8 miles in and heretofore unrecognized, parallels the range border length but at a distance of from 1 to 3 miles to the west of the mountain front; and (.6) no Basin Range fault crosses the City Creek Spur, as suggested by both Beeson and by Gilbert; and (7) the most recent movement in the fault zone did not affect all of the faults and was definitely a vertical uplift of the Wasatch Mountain block. An Electronic Method of Obtaining Timing Pulses from a Standard Clock R. Lee Aamodt Department of Physics, University of Utah A small capacitance variation", resulting from the passage of small wire between two closely spaced parallel wires may be used to vary the impedance of a "low CIt tuned circuit, inductively coupled to a small oscillator. The change in plate loading of the oscillator changes the mode of oscillation from continuous to in terrupted or "super regenerative" oscillations. The grid bias vol tage of the oscillator then changes from "direct voltage" to "inter rupted direct voltage" and may be used to trip a gaseous tube. Grid leak resistance, degree of coupling and tuning of the coupled circuit are variable and should be adjusted for optimum results. a ... .... ... ... I f the moving small wire be fastened to a clock pendulum the gaseous tube will be tripped whenever the wire passes between the two fixed wires and short accurately timed pulses may be obtained from the relay. No damping of the clock has been ob served. _ .... Bottom Sediments from the Mississippi River Delta and the Gulf of Mexico .Harold J. Bissell Brigham Young University 200 More than 225 samples from 28 Pig got cores, and more than samples from as many grab samples from the subaqueous portion of the Mississippi River delta and from the Gulf bottom out to a depth of 8000 feet have been analyzed for size distribu tion, calcium carbonate, total moisture, and organic matter. Those from near shore are characterized by well-developed thin bedding and dark laminations, nearly equal amounts of silt and clay, and low calcium carbonate content. Those from deeper water are lighter, high in clay and in calcium carbonate, bedding is poor, and Foraminifera are abundant. .... |
