Add the end of last month, I walked away out of the city and stay at small village and at the part of foot of small hill. On the way out of fly camp on the creek, it was the flood plain area and interested in that material. Looking for the material was fine to coarse sandy size, abundant quartz, abundant sulfide feldspar, rare mica, rare pyrite, fragment iron, and some soil, it is look like an alluvial. The shape was dominant sub angular, angular with rare of sub rounded, and the size very fine to coarser sand and I quite question that was the recent sediment cause of the material is loos , and transported from the around area no matter what is the original. But I would like to say also "Alluvial" if that was the material sediment transported from the original insitu hardrock. The hard rock can be volcanic or igneous rocks and metamorf . The interested point here is the base metal content on that material, it will be as the tracker to be identify the original rock where the material came from. Otherwise the sediment materials can be allow the host rock and how far.
