The US is dependent on foreign imports of placer heavy minerals for a majority of its ilmenite and rutile, and virtually all of its monazite requirements. Although sand deposits in the SE US are important domestic sources of these heavy minerals (HM) and a number of other less well known heavy mineral species, global onshore reserves of placer minerals may fall short of demand in as few as 20

Possibly these heavy mineral ratios cannot be applied so easily in the same manner in the case of the studied thick pile of Scotia offshore sediments because they have a wide age range between Early Mesozoic to Late Cenozoic; however, supposing that the same land mass was effectively the main source of the offshore sediments, these ratios might have some similar implications.
