稀有气体同位素地球化学研究的新领域、新动向

最近十多年来，国际稀有气体同位素地球化学研究紧随地球科学的发展态势，开始涉入一些新的研究领域，特别是在地下水、极地和高原冰雪、海洋和湖泊沉积等非常规领域，研究内容涵盖了水源示踪、地下水测年、气候变化、岩石暴露年龄、岩石剥蚀速率等问题。这些新动向值得国内同行及早予以关注，同时应及时跟进和发展，以尽快与国际同一研究领域接轨。

New Research Fields and New Development Tendency on Noble Gas Isotopic Geochemistry

The study on noble gas geochemistry has stretched to some new and more fields as other geosciences development during the past decade, especially in ice and firn researches on the polars and mountains, groundwater, sediments in the oceans and marines, lakes and other nontraditional geoscience fields, research contents cover such as tracing for the water origins, dating for the water, climate change, exposure age of the rocks, erosion rating, etc. All these new development are worthy of paying more attentions, and the internal geoscientists should try to follow this tendency and explore this field to catch up with the international development level.
