Ti content as an indicator of zircon crystallization

temperature but its concentration is quite low the

inherent incompatibility of Ti in zircon leads to expected

levels in the 0.3–50 ppm range under most circumstances

(corresponding to 500–900C). Now I am confused if Ti bearing phases co.crystallized with these zircon can effect this thermometer or not .Even paragenitically Zircon is late than Ti associated phases .
