연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

경상분지 남동부에 위치한 양산단층 동편의 화강암질암, 화산암류, 퇴적암류를 대상으로 총 77개 지점으로부터 독립적으로 정향된 542개의 코어시료를 채취하여 대자율 이방성(AMS) 연구를 실시하였다. 총 대자율 측정, 고온대자율 실험 및 등온잔류자기 획득실험을 통하여 연구대상 암석들의 주 자성광물이 자철석 위주의 티탄자철석계열의 것임이 밝혀졌다. 연구의 주 대상암체인 화강암질암에는 자기적 엽리구조와 자기적 선구조 모두가 존재하고 있으며, 자기적 엽리구조의 주향은 북동-남서가 지배적이다. 이 자기적 엽리구조는 화강암질암의 변형에 대한 강한 저항의 물성, 주변 모암의 자기적 엽리구조와의 불일치, 고화 이후 취성변형으로 만들어진 소단층이나 절리 등의 지질구조와의 모순점, 현미경에서 관찰되는 조직 등의 증거로부터 마그마가 관입정치하여 완전히 고화되기 전에 응력을 받아 생성된 일차 미세구조(primary fabric)로 판단된다. 이 북동-남서 주향의 자기적 엽리구조는 북서-남동의 압축력으로 만들어질 수 있는데 이러한 응력은 양산단층의 좌수향 주향운동의 산물로 해석된다. 연구지역 화강암질암의 연령이 약 $60\sim70Ma$로 알려져 있음을 감안하면 양산단층은 이 시기(백악기 말에서 신생대 초)에 걸쳐서 좌수향 주향이동 운동을 하였음을 알 수 있다.
