The Determination of Cooling Rates Based on the Oxygen Isotope Systematics of Igneous Rocks

首席研究员将调查假设， 测得的氧同位素 长英质火成岩中共存矿物的分馏 和冷却速率的关系。 将对快速冷却和缓慢冷却物体的样品进行研究。 如果成功，所产生的数据也将提供一个有价值的新的 确定造山带冷却和隆升速率的工具 是的

The principal investigator will investigate the hypothesis that a correlation exists between the measured oxygen isotope fractionations among coexisting minerals in felsic igneous rocks and cooling rate of the rocks as determined by 40Ar/39Ar studies. Samples will be studied from both fast- and slow-cooling bodies. If successful, the resulting data would also provide a valuable new tool for the determination of cooling and uplift rates in orogenic terranes.
