  • A chemical and petrographic study of refractory inclusions from Kaba (CV3) chondrite

    Creator:
    Liu, Yun-gang
    Abstract:
    Refractory inclusions from Kaba (CV3) chondrite were studied by instrumental neutron activation analysis (INAA) and electron probe microanalysis (EPMA). The inclusions observed cover a wide range of chemical patterns, mineral assemblages and textures, indicating the complexity of early solar nebular conditions. The elemental abundances normalized by Cl chondritic abundances vary...

  • Pathological and ecological aspects of decline and mortality of Chamaecyparis nootkatensis in southeast Alaska

    Creator:
    Hennon, Paul Edward
    Abstract:
    Alaska-cedar (Chamaecvparis nootkatensIs (D. Don) Spach) is a valuable tree that is suffering from a serious decline and mortality of unknown cause throughout southeast Alaska. Epidemiological and pathological studies were initiated to determine if a pathogen is the primary cause of this problem. By examining old aerial photographs and by...
