Volcanic and plutonic rocks have a vast range in chemical and textural composition, but the exact mechanism by which this is generated is not yet always clear. I want to determine the respective roles of magma-mixing and crystal fractionation in the generation of volcanic rocks. I will do this by dissecting solidified rocks and looking at their chemical composition and texture. Secondly, I want to see if bubbles can play an important role in the generation of magma-mixing and crystal fractionation. Bubble-crystal interaction is an important industrial process, but has been little examined in a geological context. Volcanic and plutonic rocks are common on Earth and other planets, and many types of mineral deposits are associated with them. Hence, a clearer understanding of the fundamental processes that produce magmatic diversity can have implications in many fields of geology, such as economic geology, volcanology and the general understanding of earth processes.

火山岩和深成岩在化学和结构组成上有很大的差异，但其产生的确切机制尚不清楚。我想确定岩浆混合和晶体分馏在火山岩形成中各自的作用。我将通过解剖凝固的岩石并观察它们的化学成分和质地来做到这一点。其次，我想看看气泡是否在岩浆混合和晶体分馏的产生中发挥重要作用。气泡-晶体相互作用是一个重要的工业过程，但很少在地质背景下进行研究。 火山岩和深成岩在地球和其他行星上很常见，许多类型的矿床都与它们有关。因此，更清楚地了解产生岩浆多样性的基本过程可能对许多地质学领域产生影响，如经济地质学、火山学和对地球过程的一般理解。
