摘要

印度尼西亚东爪哇的拉蒙甘火山场(LVF)经历了多次火山喷发,火山灰颗粒的性质和形态各异。本研究对幼灰颗粒进行了纹理、形态计量和地球化学分析,以阐明影响其异质特征的因素。研究确定了两种不同类型的幼灰:A(黑色和棕色灰烬)和 B(橙棕色灰烬),反映了不同的破碎过程。不同玄武岩成分(导致不同的质地、流变特性和/或冷却历史)的 A 型幼灰呈块状至略微细长状,这突出表明了喷气熔岩过程是控制其形状的主要因素。与此相反,幼体 B 颗粒的不规则流体形状表明玄武安山岩岩浆的岩浆碎裂。这项研究揭示了不同的岩浆特性会产生不同的火山灰成分,而碎裂动力学则控制着 LVF maar 复合体的火成岩形状。我们的综合方法强调了在解释异质火山灰沉积时考虑多种变量的重要性。

Characteristics of ash particles from the maar complex of Lamongan Volcanic Field (LVF), East Java, Indonesia: How textural features and magma composition control ash morphology
The Lamongan Volcanic Field (LVF), East Java, Indonesia, has experienced numerous maar eruptions, producing varied properties and morphologies of ash particles. This study conducted textural, morphometric, and geochemical analyses of the juvenile particles to elucidate the factors governing their heterogeneous characteristics. Two distinct types of juvenile ash were identified: A (black and brown ash) and B (orange-brown ash), reflecting different fragmentation processes. The blocky to slightly elongate shapes of juvenile A across heterogenous basaltic compositions (resulting in variable textures, rheological properties, and/or cooling histories) highlight the phreatomagmatic process as the primary control of their shape. In contrast, the irregular-fluidal shapes of juvenile B particles indicate magmatic fragmentation of basaltic andesite magma. This study reveals that variable magma properties yield diverse ash components, yet fragmentation dynamics govern pyroclast shapes in the LVF maar complex. Our integrated approach emphasizes the importance of considering multiple variables when interpreting heterogeneous volcanic ash deposits.
