An Interface Between The Grass Geographic Information System And Oracle Relational Detabase Management System, David Gordon Buker
An Interface Between The Grass Geographic Information System And Oracle Relational Detabase Management System, David Gordon Buker
FIU Electronic Theses and Dissertations
A query and display interface has been developed between the GRASS geographic information system and the SQL-based ORACLE relational database management system (DBMS) . This interface enables multiple non-spatial attributes of GRASS map features to be maintained with the DBMS. GRASS alone is capable of storing only one attribute per feature. The interface allows the user to provide both spatial (GRASS) and non-spatial (SQL) selection criteria for any query. Spatial selection methods include picking items from the GRASS map with a mouse, and specifying areas of interest with user-drawn (via a mouse) polygons and transects. The results of the combined …
Petrology And Geochemistry Of Some High Pressure Rocks From Northern Part Of Rio San Juan Complex, Dominican Republic, Khandaker I. Anam
Petrology And Geochemistry Of Some High Pressure Rocks From Northern Part Of Rio San Juan Complex, Dominican Republic, Khandaker I. Anam
FIU Electronic Theses and Dissertations
The Rio San Juan Complex is an important occurrence of high pressure/low temperature rocks in the circum-Caribbean region which contains both coherent blueschist units and two varieties of melange in the same area. The melanges contain a diverse assemblage of blocks of various sizes, different degrees of metamorphism, and mineral assemblages. Some high pressure blocks show two stages of metamorphism. The earliest stage is characterized by high pressure-low temperature conditions and the second stage is characterized by high pressure-lower temperature conditions. The geochemistry of thirteen samples from the Rio San Juan Complex has been studied and data have been compared …
A Model Of The Hydrothermal System At Casa Diablo In Long Valley, California, Based On Resistivity Profiles And Soil Mercury Analyses, John David Arfstrom
A Model Of The Hydrothermal System At Casa Diablo In Long Valley, California, Based On Resistivity Profiles And Soil Mercury Analyses, John David Arfstrom
FIU Electronic Theses and Dissertations
A description and model of the near-surface hydrothermal system at Casa Diablo, with its implications for the larger-scale hydrothermal system of Long Valley, California, is presented. The data include resistivity profiles with penetrations to three different depth ranges, and analyses of inorganic mercury concentrations in 144 soil samples taken over a 1.3 by 1.7 km area. Analyses of the data together with the mapping of active surface hydrothermal features (fumaroles, mudpots, etc.), has revealed that the relationship between the hydrothermal system, surface hydrothermal activity, and mercury anomalies is strongly controlled by faults and topography. There are, however, more subtle factors …
