description |
The study area (40455 km2) covers the Southern Mountains Zone of East
Java, Indonesia. This zone is known as mineral districts, the distribution of 75 Au-
Cu occurrences in this area was examined in terms of spatial association with
various geological phenomena. Analysis of these relationships, using GIS and
weights of evidence method, has predicted areas of high mineral potential.
The weights of evidence method is a probability based technique for
mapping mineral potential using the spatial distribution of known mineral
occurrences. Mineral potential maps predicting the distribution of Au-Cu
occurrences were generated from six evidence maps that consist of NE-SW
lineaments, NW-SE lineaments, host rocks, heat sources, clay alteration and
limonitic alteration.
The result of Au-Cu potential map indicates that about 6472 km2 (16%)
of the study area as favourable zones. It predicts correctly 54 (96%) of the 56
model deposits and predicts correctly 18 (95%) of the 19 validation deposits, has
two main prospective target areas for future exploration are located in southwest
of research areas like Pacitan, Trenggalek, Ponologo and Wonogiri Regency and
located in southeast of research areas as Banyuwangi and southeast of Jember
Regency. The potential areas of Au-Cu occurrences in research area is associated
with NE-SW structure/lineaments, dominated surrounding the Tertiary intrusive
rock unit and hosted in Miocene to Oligocene lithology rock unit.
