Magma Chamber Recharge in the Palisades Sill

该项目将详细研究注入新岩浆脉冲的侵入层中发生的成分、矿物学和结构变化。 希望收集到的数据将为了解当新的原始岩浆脉冲注入包含预先存在的更进化岩浆的房间时发生的岩浆混合的性质和程度提供新的见解。 该数据还可能有助于确定岩浆室中沿结晶前沿的晶体-液体糊状区域厚度的一些最小值，和/或为快速冷却的深成岩中的间隙熔体迁移提供一些最小距离

This project will examine in detail the compositional, mineralogical, and textural changes that occur at these horizons in the intrusion where a new pulse of magma has been injected. It is hoped that the data collected will provide new insights into the nature and extent of the magma mixing that occurs when a new pulse of primative magma is injected into a chamber that contains a pre-existing more-evolved magma. The date may also help to establish some minimum values for the thicknesses of crystal-liquid mush zones along the crystallization front in magma chambers, and/or provide some minimum distances for interstitial-melt migration in rapidly cooled plutonic rocks
