* FTSE pares early gains
* Miners up but geopolitical, inflation worries linger
* Banks lower, HSBC falls after broker downgrades
LONDON, March 1 (Reuters) - Strength in miners kept Britain's top share index in positive territory at midday on Tuesday after supportive data overnight from China.
Lingering geopolitcal concerns and inflation worries saw many stocks pare early gains with banks and retailers among the top fallers.
At 1149 GMT, the FTSE 100 <
> was 2.18 points higher at 5,996.19. The index fell 1.3 percent last week as tensions in the Middle East and North Africa saw oil prices soar, threatening global economic recovery."There remains uncertainty which is preventing this market from pushing on," Jimmy Yates, head of equities at CMC Markets, said.
"Fund managers are shuffling their portfolios out of riskier assets for the time being and, given the weighting of the FTSE towards commodity-driven assets and banks, that is stunting progress."

Miners <.FTNMX1770>, which have fallen early in 2011 on worries over inflation in emerging markets and dented by political tensions in the Middle East, bobbed higher.
Chinese manufacturing data showed growth slowed in February, helping dampen fears about China's economy overheating and the need for further monetary tightening in the world's major commodity consumer.
"The China data provides some support for miners, though overall the picture remains mixed," Mic Mills, head of electronic dealing at ETX Capital, said.
Energy <.FTNMX0530> stocks were mixed. Crude prices <LCOc1> held above $112 per barrel, although off multi-year highs, on supply worries as unrest continued in Libya and the Middle East.
Traders said the session's slightly more bullish tone among investors was underpinned by comments from Warren Buffett, chairman of investment firm Berkshire Hathaway <BRKa.N>, which suggested stocks may be cheap. [
