NEW YORK, Nov 9 (Reuters) - Gold surged and the dollar rose against the euro on Tuesday on uncertainty over high sovereign debt in euro zone countries, while U.S. stocks paused after a recent rally drove indices to two-year highs.
Gold extended its record highs to a fourth straight session and oil rose to a two-year high, helped by inflation fears and euro zone debt worries. The Federal Reserve's decision to undertake more stimulus has contributed to the dollar's recent downward trend and led some to worry about inflation.
"We have a combination: inflation fears, currency market uncertainty, fears about the financial strength of some countries," said Alexander Zumpfe of Heraeus Metals.

COMMODITIES RISE, G20 EYED
