QUESTION 6 Iron is most often formed within higher concentration bands because (A) (B) (C) (D) high rainfall leads to the concentration of iron ore due to leaching. higher porosity reservoir rocks allow high concentrations of iron ore to precipitate under a cap rock. zones within convergent plate boundaries cause high-pressure mineral assemblages to form in distinct zones. the high density of iron leads to it being concentrated in the deeper parts of channels found within sedimentary basins.
QUESTION 15 siltstone Q What is the most likely type of mineral resource to be found at location A? (A) banded iron ore (B) mineral sands (C) bauxite (D) gold
QUESTION 2 Economical gold-bearing layers are most likely located in (A) asedimentary sequence with an organic-rich source rock. (B) fractures and joints surrounding a massive granite body. (C) joint planes in an exhalative massive sulfide complex. (D) an alluvial deposit in an igneous granite complex.
QUESTION 5 Mineral sands deposits are formed (A) in higher porosity reservoir rocks allowing greater concentrations of ore minerals to precipitate under a cap rock. (B) by the weathering of mineral-rich rocks and subsequent dissolution of minerals into oceans and streams. (C) by the physical concentration of eroded mineral grains into placer deposits due to their specific gravity. (D) in convergent plate boundaries causing high-pressure mineral assemblages to form in distinct zones.
