* Banks fall, details of U.S. rescue package awaited
* Commodity shares track crude and metal prices higher

LONDON, Sept 22 (Reuters) - European shares fell on Monday, led by banks as investors awaited details of a U.S. rescue package for the financial sector, offsetting a rise in commodities stocks tracking higher metal and crude prices.
At 0825 GMT, the FTSEurofirst was down 0.78 percent at 1,141.79 points after an 8.2-percent rise on Friday, its biggest one-day gain on record.
Banking stocks were the top weighted losers on the index with HSBC <HSBA.L>, Barclays <BARC.L>, Societe Generale <SOGN.PA>, Banco Santander <SAN.MC> and Lloyds TSB <LLOY.L> down between 1.25 and 4.5 percent.
On Friday, the European banking sector jumped following temporary bans on short-selling of financial stocks and on the U.S. government's broad bailout plan.
"We need to see more details from the rescue package. What is missing is the price the U.S. authorities are going to pay for the toxic assets. This will determine the further performance of the banking sector," said Heino Ruland, analyst at FrankfurtFinanz.
Washington proposed a $700-billion taxpayer-funded plan in an effort to ease the global credit crisis and reverse the U.S. housing slump.
"In the long run, the package will be a burden on the U.S. economy as taxpayers will have to pay. Investors are disappointed with no further news details of the package," added Ruland.
Meanwhile, Goldman Sachs <GS.N> and Morgan Stanley <MS.N> are giving up their investment bank status in return for cover under the U.S. Federal Reserve's wing to survive the crisis that forced rival Wall Street firm Lehman Brothers <LEHMQ.PK> to file for bankruptcy.
UBS <UBSN.VX> was up 2 percent.
The FTSE 100 <
> index was down 0.76 percent, the German DAX <GDAXI> was 0.28 percent lower and France's CAC 40 < > slipped 0.6 percent.
COMMODITIES TOP GAINERS
Energy shares were higher after crude prices <CLc1> gained $1.90 to $106.45 a barrel. BP <BP.L>, Royal Dutch Shell <RDSa.L> and BG <BG.L> were up 1.1-2.3 percent.
Miners tracked metal prices higher with copper <MCU3=LX> up 2.2 percent. Eurasian Natural Resources <ENRC.L>, BHP BILLITON <BLT.L>, Vedanta Resources <VED.L> and Xstrata <XTA.L> rose between 2.3-3.85 percent.
But the surge in commodity prices also sparked inflation fears, hurting retailers.
In the food and drug retail sector, Carrefour <CARR.PA>, Ahold <AHLN.AS> and J Sainsbury <SBRY.L> were down between 1.4-2.7 percent.
In the chemical sector, which uses oil-based inputs, Bayer <BAYG.DE>, Akzo Nobel <AKZO.AS> and Air Liquide <AIR.PA> were down between 2-2.2 percent.
EDF <EDF.PA> gained 0.85 percent after the Guardian reported lawyers for British Energy <BGY.L> and the group were last night completing paperwork on a 12.4 billion pound takeover of the nuclear power generator, with a view to signing off the deal in time for a stock market announcement on Tuesday.
Air France-KLM <AIRF.PA> was down 2.3 percent after RBS cut the group to "sell" from "hold".
ASML <ASML.AS> was 4.3 percent lower as ING downgraded it to "sell" from "hold".
Analysts said that the bailout package may be positive for stocks but added the damage from a year-long credit crisis had spread further into the economy.
"From a top down stand point this will not change too much in Europe, which is clearly facing a recession," said Ruland. (Editing by Paul Bolding)
