U-Pb and Ar/Ar dates from the Talladega belt, southernmost Appalachians, provide insight into the timing and nature of pre-Alleghanian tectonism in this region. Low-grade metasedimentary rocks of the Talladega belt represent the outermost preserved portions of the southern Laurentian margin, thus recording the earliest orogenic events that affected the margin, in addition to later overprinting ...

Water is the principal limiting resource for Californian Mediterranean-climate plants. The relationship between rainfall variation and the abundance and distribution of plant species was investigated at the Jasper Ridge Biological Preserve near Stanford University. Five years of rainfall data (1986-1990) were combined with a yearly census of plant species on a 100m transect to relate inter-annu...

Browsing is part of the information seeking process, used when information needs are ill-defined or unspecific. Browsing and searching are often interleaved during information seeking to accommodate changing awareness of information needs. Digital Libraries often support full-text search, but are not so helpful in supporting browsing. Described here is a novel browsing system created for the Gr...

This paper focuses on the mapping of alteration minerals and linear structures associated with gold mineralization in Giyani Greenstone Belt (GGB). Spectral Information Divergence (SID) Linear Unmixing (LSU) classification algorithms were applied to ASTER data using image extracted endmember spectra which match spectral profiles predominant (biotite calcite) related GGB. Directional convolution...
