| 總結: | This research investigat the integration of geophysical data induced
polarization method data in to geographic information system (GIS) with
study manganese deposit exploration in Kampar Regency Riau Province.
Induced Polarization method is difficult method to be integrated in GIS
because the result of data processing produced subsurface raster vertically
(pseudosection). Potency of manganese deposit in research area found in
metasediment rock as phyllite and quartsite. The result of field observation
interpretation found manganese shaped vein indicated as result from
hydrothermal process.
Integration process in this research including building geodatabase,
analysis of geophysics data, and integrated data visualization. Building
geodatabase classified base on data types, they are geophysics and geology
data. Geodatabase produced later exported to.xml format till produce data
model can be used another user. Analysis process including transformation
from pseudosection datum point till produced new data as merge datum point
from all line to spatial analysis. Exploring data showing that data produced not
distributed normally, till need to normalize process. This matter based the
reality that geophysical data is continuous data. Result of spatial analysis
produced surface map to resistivity and chargeability value. Deliniation of
anomaly as geophysics data transformation to geological data become basic of
reclassification process. This stage base on raster value on surface map in
borehole 1 and 2 are 2000 �m of resistivity and 30 msec of chargeability as
range of manganese value. This result later conducted multiple map analysis
(overlay) with Boolean operator of reclassification result value, and produced
manganese potential area. Manganese potential area observed in borelhole 2
dan 3 shaped irregularly and layering. All process in integration and analyst is
that has long step and modeling with model builder. From this model builder
will give easiness to anatother user to apply this method. |
