Homer's chimaera fires (SW of Antalya/Turkey); burning abiogenic methane gases; are they generated by a serpentinization process related to alkalic magmatism?

Gas seeps that feed the "everlasting" fires of the Chimaera site above the ophiolitic complex of Antalya (Turkey) consist primarily of methane, which may be derived by serpentinization of mafic/ultramafic rocks and/or cooling of an alkalic igneous mass at depth. Isotope values for the methane suggest this abiogenic origin. Ancient accounts attributed the fires to a mythical monster, the Chimaera, which was slain by Bellerophon. The hypothetical igneous mass could represent the youngest and southernmost of a series of volcanic complexes that developed since the Mid-Miocene along a northerly trending zone of crustal extension above a major fracture zone (Isparta Angle) that separates two major segments of the subducted African slab below Anatolia.
