Volcanology of voluminous felsic lavas

大量熔岩（> 100立方公里）的喷发在整个地质时期都有发生，但在人类历史上没有记录。这些熔岩是形成大陆的巨大火山区的主要部分。在南澳的高勒山脉火山中已经发现了极好的例子。人们对火山爆发的机制知之甚少，但这些事件是了解地球深处大规模熔融过程和大陆形成的关键。这项研究将使用从南澳大利亚州的例子之一，以限制源火山中心的性质和位置，并澄清外流机制的现场数据。

Eruptions of voluminous lavas (>100km3)have occurred throughout geological time but not in recorded human history. These lavas are a major part of very large volcanic areas that form the continents. Excellent examples have been identified in the Gawler Range Volcanics, South Australia. Little is known about the eruption mechanisms and yet these events are the key to understanding large-scale melting processes deep in the Earth and continent formation. This research will use field data from one of the South Australian examples to constrain the nature and position of the source volcanic centre and to clarify outflow mechanisms.
