Abstract :

Hasan Abad Gold-Antimony prospect area is located in the north of Khorasan Razavi and 45 km to the sought of neishabour. The prospect area is located to the northern section of central Iran microcontinent with respect to geological division of Iran. On the basis of field observation and laboratory investigation 13 subvolcanic and intrusive bodies were identified during surface and subsurface studies. The Granite body has the most extension on the surface and it is the wall rock of quartz Gold-Antimony vein and was drilled in granite unite on the basis of IP/RS survey in the exploration area. In this work IP/RS pseudo section were interpreted using drilled core observation and studies. chargeability anomaly is in the south eastern part of Gold-Antimony vein small and is at greater depth. It extend northeast southwest and is highest in the center of the vein and is dissected by a fault. Chargeability anomaly extends towards northwest of the main Gold-Antimony vein and is observed as three small discontinuous anomaly. High chargeability anomaly and its extension in all three pseudo sections confirm the presence of conductive sulfide and correlates with the results of observed mineralization on the drilled cores. Observed milonite in drilled core and dissection of anomaly infer a fault which milonites the Quartz Monzonite subvolcanic body before the creation of mineralization. Detailed surface and subsurface geological, alteration and mineralization studies correlate well with IP/RS anomalies and confirm them.
