Correlation of Phreatomagmatic Depositional Features with Eruptive Events at the Ukinrek Maars, Alaska

拟议的项目将把阿拉斯加Ukinrek Maars的沉积物和个别地层与记录的水火山爆发事件联系起来，以便了解火山喷发和沉积的过程。我们的研究结果将为从未观测到喷发的地方的沉积物特征推断不同的呼吸岩浆喷发类型提供一种手段。进行这项研究的根本原因是为了帮助了解水火山过程的危害评估。水火山爆发通常包括“爆炸”事件，这是所有爆发中最具破坏性和危险性的事件之一。由于这些矿床常被误认为是改造过的火山矿床，因此识别这些矿床对灾害评价具有重要意义。

The proposed project will correlate deposits and individual strata with recorded hydrovolcanic eruptive events at the Ukinrek Maars, Alaska, in order to understand the processes involved in eruption and emplacement of phreatomagmatic deposits. Our results will provide a means for inferring diverse phreatomagmatic eruption styles from the characteristics of deposits in places where the eruptions were not observed. The underlying reason for this research is to aid understanding of hydrovolcanic processes for hazards assessments. Hydrovolcanic eruptions commonly include "blast" events that are among the most devastating and hazardous of all eruptions. It is of fundamental importance for hazards evaluations to recognize these deposits, as they are commonly mistaken for re-worked volcanic deposits.
