锡石是锡多金属矿床中重要的矿石矿物,属于金红石族,当其有较高的铀-钍含量时,可以作为U-Th-Pb和Pb-Pb同位素测年的对象。因为锡石是许多锡多金属矿床中重要的矿石矿物,利用锡石U-Pb同位素测年直接测定锡多金属矿床的成矿(锡矿化)时代,是非常有潜力的一种直接测定矿床成矿时代
Cassiterite is an important ore mineral in the tin polymetallic deposit and belongs to the rutile group. When it has a high uranium-thorium content, Cassiterite can be used as a target for U-Th-Pb and Pb-Pb isotope dating. Because cassiterite is an important ore mineral in many tin polymetallic deposits, the direct determination of ore-forming (tin mineralization) age of tin-polymetallic deposits using cassiterite U-Pb dating is a very promising method for the direct determination of ore deposits Metallogenic era
