Abstract

The SHRIMP zircon U-Pb age dating was carried out for the age-unknown Haeinsa Granite located in the middle Yeongnam Massif. SHRIMP zircon U-Pb age determinations of 7 samples from the Haeinsa Granite in Geochang area show two age groups. Ages from 5 samples (M-3-1, H-1, 3, 5, 10) are $192.4{\pm}1.4{\sim}195.5{\pm}1.9Ma$, whereas ages from 2 samples (H-11 and 12) are $187.7{\pm}3.3Ma$ and $188.2{\pm}3.6Ma$, respectively.

영남육괴 중부에 분포하는 시대미상의 해인사화강암에 대한 SHRIMP U-Pb 저어콘 연대측정을 수행하였다. 거창군 일대의 해인사화강암에서 채취한 7개의 시료에 대한 연대 측정 결과, 5개 시료에서는$192.4{\pm}1.4{\sim}195.5{\pm}1.9Ma$로 대부분 오차범위 내에서 중첩되는 결과를 보이는 반면, 시료 H-11과 12의 시료에서는 각각 $187.7{\pm}3.3Ma$, $188.2{\pm}3.6Ma$의 연령을 보여 비교적 젊은 시기를 지시한다.
