Smile R Ccasmr The oyu tolgoi porphyry cu au system in the south gobi desert, mongolia, comprises five deposits that extend over 6 km in a north northeast–oriented zone. they occur in a middle to late paleozoic arc terrane and are related to late devonian quartz monzodiorite intrusions. Late devonian porphyry cu au deposits within the oyu tolgoi mineral district, mongolia, occur in a north northeast–trending zone 22 km long. they are related to quartz monzodiorite intrusions, and hosted by augite basalt lavas. the porphyry systems have been preserved beneath overturned and allochthonous stratigraphic sequences and geologic relationships suggest that fold thrust belt.
Officer Pretty R Ccasmr Hugo dummett is the largest deposit in the oyu tolgoi mineral district with measured and indicated reserves of 820 mt at 1.82% cu and 0.42 g t au (0.6% cu cut off), notable for exceptionally high grades with 329 mt at 3.0% cu and 0.76 g t au (2% cu cut off), therefore ranking as one of the most cu rich porphyry systems in the world. The oyu tolgoi cluster of seven porphyry cu au mo deposits in southern mongolia, define a narrow, linear, 12 km long, almost continuously mineralised trend, which contains in excess of 42 mt of cu. Field relationships and u pb data (zircon) are used to constrain the timing of tectonomagmatic events that occurred shortly after the formation of late devonian (~372 ma) porphyry cu au deposits at oyu tolgoi (mongolia). in the two northernmost of the several discrete porphyry centers (hugo dummett deposits), upper devonian rocks positioned stratigraphically above copper gold mineralization. Cu cut off), notable for exceptionally high grades with 329 mt at 3.0% cu and 0.76 g t au (2% cu cut off), therefore ranking as one of the most cu rich porphyry systems in the world. hugo dummett.
