한반도 남부 지역은 태평양(pacific)판의 섭입에 의한 화성활동이 매우 활발했던 지역으로 백악기 화강암류와 이와 성인적으로 밀접한 관련이 있는 것으로 추정되는 화산암류가 넓게 분포하고 있다. 여수 지역 백악기 화강암류를 형성시킨 마그마의 특성 및 지구조적 환경을 규명하고자 주성분 원소, 미량원소에 대한 지화학적 연구를 시도하였다. 연구 지역의 화성암류는 섬록암, 각섬석 흑운모 화강암, 미문상 화강암류로 구성되어 있다. 연구지역의 화강암은 칼크-알칼리(calc-alkaline) 계열로, A/NK vs. A/CNK 도에 점시해 본 마그마의 특성은 대부분 중알루미나(metaluminous)에 해당하고 I-type로 나타난다. 암석기재학적 특징으로 본역의 암석은 천소에 관입 정치된 화강암류의 암석으로, 지구조판 별도에 의하면 압축장이 작용하는 판의 경계부 즉, 화산호화강암(VAG)에 해당된다. 희토류원소의 패턴은 경희토류원소(LREE)가 중희토류원소(HREE)보다 부화된 ((La/Lu)cN=4.2-13.3) 백악기 화강암류의 전형적인 패턴과 일치하며 미문상화강암은 섬록암에 비해 Eu(-) 이상이 뚜렷하게 나타난다. 총희토류원소(σLREE) 함량은 76.2-235 ppm으로 본 연구지역의 화강암류들은 대륙연변부에서 나타나는 화강암류의 희토류원소 총함량 범위에 해당된다. 위의 지화학적 자료를 종합해 보면 여수 지역 화강암류들은 태평양판의 섭입에 의한 압축장이 작용하는 대륙 연변부에서 생성되었음을 알 수 있다.
