LONDON, Nov 19 (Reuters) - European shares fell back on Friday after strong gains the previous session, with miners lower on worries that China, the world's biggest metals user, will raise interest rates.
Most analysts remained optimistic for progress in resolving Ireland's debt crisis, but banks fell on longer-term worries about euro zone debt.
At 1005 GMT the FTSEurofirst 300 <
> index of top European shares was down 0.5 percent at 1,102.61 points, after rising 1.4 percent on Thursday.For the week the European benchmark is set to fall 0.1 percent but is up more than 70 percent from its lifetime low of March, 2009, with several major economies having emerged from recession, helped by stimulus from governments and central banks worldwide.
Optimism on a deal for Ireland helped the euro to edge up on Friday, with the dollar falling, boosting metals prices. However, this did not translate into higher share prices for miners, which gave back some of the previous session's gains.
Anglo American <AAL.L>, BHP Billiton <BLT.L> and Rio Tinto <RIO.L> fell between 1.6 and 2.1 percent.
Investors remain worried that China, the world's biggest metals user, may raise interest rates, with inflation running at a 25-month high.
"There's concern the Chinese may look to tighten monetary policy. Inflation in China is quite high, and the Fed money printing is exporting inflation," said Michael Hewson, market analyst at CMC Markets.
"And even if there is a resolution for Ireland, all it does is shift the focus back to the mainland periphery."
Ireland insisted its low rate of corporation tax was "non-negotiable" as it discusses an aid package worth tens of billions of euros from European partners and the IMF for its shattered banks.
Nevertheless some analysts remained optimistic.
"Ireland is a focal point for the markets and it looks as though something that was a destabilising influence in the euro zone is heading for a resolution, though the sticking point will be the corporate tax issue," said Mike Lenhoff, chief strategist and head of research at Brewin Dolphin Securities in London.
"Anybody who has sat back in the hope there would be a buying opportunity has been disappointed."
Bank of Ireland <BKIR.I> was among the gainers, up 6.9 percent, though most banks were lower, including Spanish heavyweights BBVA <BBVA.MC>, and Banco Santander <SAN.MC>, 1.5 and 2 percent lower respectively.
Barclays <BARC.L>, Standard Chartered <STAN.L> and UBS <UBSN.VX> fell between 1.2 and 2.2 percent.
Across Europe, Britain's FTSE 100 <
> and France's CAC40 < > fell 0.7 and 0.2 percent respectively. Germany's DAX < > was flat. The Thomson Reuters Peripheral Eurozone Countries Index <.TRXFLDPIPU> was flat.
ZODIAC FALLS
Among individual stocks, Zodiac <ZODC.PA> fell 6 percent after French defence group Safran <SAF.PA> says it will not make an offer for the French aviation parts supplier, ending months of uncertainty over its intentions. Safran rose 4.9 percent. [
