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

拟议的项目将把矿床和个别地层与阿拉斯加乌金雷克马尔斯记录的火山喷发事件联系起来，以了解云母岩浆矿床喷发和侵位所涉及的过程。我们的结果将提供一种手段，从没有观察到喷发的地方的沉积特征来推断不同的岩浆喷发类型。这项研究的根本原因是为了帮助了解火山喷发过程，以进行灾害评估。火山喷发通常包括“爆炸”事件，这是所有喷发中最具破坏性和最危险的事件之一。识别这些矿床对于危害评估至关重要，因为它们通常被误认为是重新加工的火山矿床。

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.
