K - ar age of an illite from alteration rock in the contact zone around lianhuashan porphyry is 38. 6ma. with referencing to the main metallogenic period of yulong copper metallogenic zone and of ailaoshan gold metallogenic zone, it is suggested that the time of formation of deposits in the district studied is probably in a period of time from 38. 6ma at earliest to 20ma at latest. this time is equivalent to the origination time of two important tectonic events, i. e., lanping movement and the turning point when ailaoshan - red river fault turned from sinisteral into dextral
