Mineralization Temperature of Bamianshan New Type Fluorite Deposit of Zhejiang

There are 4 mineralization periods in the Bamianshan fluorite deposit,among them main periods are 1st and 4th.On great deal of datum,conclusions are followed:The temperature area is 240～121℃ and average temperature is 176℃ of fluorite-forming in first mineralization period that is middle-low temperature that mainly is low temperature thermal mineralization process.The temperature area is 1221～169℃ and average temperature is 734℃ of thermal fluid in second mineralization period that is alteration-mineralization-process of high-temperature gas-fluid and fluorite forms in the middle-low temperature stage.The temperature area is 168～123℃ and average temperature is 142℃ of fluorite-forming in third mineralization period that is low temperature thermal mineralization process.The temperature area is 246～115℃ and average temperature is 150℃ of fluorite-forming in fourth mineralization period that is middle-low temperature that mainly is low temperature thermal mineralization process.
