我们要感谢Geist等人（Contrib Miner Petrol，2023）提供机会进一步讨论我们的论文“冰岛Hekla火山下的岩浆停留时间长还是短？”（Sigmarsson等人Contrib Miner Petrol 177：13，2022）。争论的焦点集中在赫克拉火山岩浆的起源上，即它是通过（1）分离结晶和喷发前长时间的地壳停留，还是（2）蚀变玄武质地壳的部分熔融和向地表的短时间转移。我们不同意Geist等人（Contrib Miner Petrol，2023年）提出的论点，反对海克拉英安岩起源于角闪岩脱水熔融的模型，该模型仍然解释了迄今为止在海克拉岩浆套件中获得的大多数（如果不是全部）结果。
We would like to thank Geist et al. (Contrib Miner Petrol, 2023) for the opportunity to further discuss the arguments presented in our paper “Long or short silicic magma residence time beneath Hekla volcano, Iceland?” (Sigmarsson et al. Contrib Miner Petrol 177:13, 2022). The disagreement centers around the origin of the silicic magmas at Hekla, namely whether it is by (1) fractional crystallization and a long crustal residence time before eruption or (2) partial melting of altered basaltic crust and short transfer time to the surface. We disagree with the arguments presented by Geist et al. (Contrib Miner Petrol, 2023) against the model for the origin of dacite at Hekla from dehydration melting of amphibolite, a model that still explains most if not all results obtained so far on the Hekla magma suite.
