지표환경에서의 마그네슘 동위원소 분별 = Magnesium isotope fractionation during surficial processes

다국어 초록 (Multilingual Abstract)

With the advent of analytical technique and mass spectrometry, non-traditional stable isotopes have been widely used in earth and environmental sciences. However, little studies have been conducted in South Korea.
Magnesium (Mg) isotopes can be used as a tracer for understanding global climate change, seawater chemistry and nutrient cycling in soil. To this end, Mg isotope fractionation during geological Mg cycling should be quantified.
This review introduces major factors (primary mineral dissolution, secondary mineral formation, adsorption, plant uptake and carbonate mineral precipitation) causing Mg isotope fractionation during surficial processes. This review also introduces the principle of Mg isotopes and analytical methods. Finally, recent studies are reviewed in order to see how and to what extent Mg isotope fractionation would occur according to each factor.

최근 분석법 및 질량분석기의 발달로 인해 비전통 안정동위원소의 지구과학적 활용이 두드러지지만, 이에대한 국내에서의 활용은 미진한 실정이다. 마그네슘 동위원소는 전 지구적 탄소순환, 해수 화학, 양분순환(nutrient cycling)을 이해하는 지시자로 활용될 수 있으며, 이를 위해서는 Mg 순환과정 중 발생하는 동위원소분별에 대한 이해가 선행되어야 한다. 따라서 본 논평에서는 지표환경에서 마그네슘 동위원소 분별을 일으키는요인(주요 광물 용해, 이차광물 생성, 흡착, 식물 섭취 및 탄산염 광물 침전)에 대하여 소개하고자 한다. 먼저 마그네슘 동위원소의 개념, 질량분석기를 활용한 분석법을 살펴보고 마지막으로 최근 연구결과를 통한 지표환경에서 마그네슘 동위원소 분별을 일으키는 요인 및 기작에 대하여 살펴보고자 한다.
