Bulletin of the Mineral Research and Exploration
The aim of this research is to compare index overlay and TOPSIS (based on AHP weight) for predictive Skarn potential map. In this paper, for Calcic Iron Skarn mineralization, criteria and subcriteria introduced and ranked for generating mineral prospectivity map. The values of final prospecting maps for Skarn deposit by index overlay and TOPSIS methods was specified by dividing the prospectivity values into 10 classes. For better comparison,values assign to classes base on their priority in mineral exploration. The comparative analyses of index overlay and TOPSIS integration methods, has been performed by selecting four GCPs for field checking. Field observation …

Turkish Journal of Earth Sciences
Several outcrops of spectacular feather-like hornblende aggregates occur in the phyllites of the Gol-e-Gohar complex (southeast of Iran) and form special Garbenschiefer rock types. The Gol-e-Gohar complex, as a part of the southern Sanandaj-Sirjan metamorphic zone, contains a succession of metabasites, phyllites, and slates intruded by dioritic intrusions. There are two types of hornblendes in the phyllites; the first one is concentrated around the fractures and the second one is randomly distributed in the rocks and forms radial feather-like hornblende aggregates. Petrographical and chemical characteristics of these two shapes of hornblendes are the same, except the latter is developed parallel …
