Reconnaissance Investigation Of The Alluvial Gold
reconnaissance investigation of the alluvial gold deposits in the north takhar area of interest, takhar province, afghanistan By peter chirico, katherine malpeli, and thomas moran open-file report usgs afghanistan project product no. 184. u.s. department of the interior u.s. geological surveynov 03, 2016 many western gold placers, particularly those exploited by bucket-line dredges, have been sampled by churn drilling and it can be said generally that this method adapts well to the dredge operators needs. the basic drilling equipment consists of a heavy casing, a chisel-shaped bit suspended from a drill line and a vacuum-type sand pump.gold deposit was created by hydrothermal activity. It has shaped by quartz vein.1 We hope that investigation by induced polarization method can give dissemination map from alteration rock as indicated gold mineralization. gold mineralization zone will give high pfe and the equipment will be calibrated if input of receiver
