Temperature-composition-time(T-X-t)data from authigenic K-feldspar:An integrated methodology for dating fluid flow events

摘要

Integration of fluid inclusion analysis with high spatial resolution Ar-Ar dating of K-feldspar cements has been used to resolve and reconstruct palaeo-fluid flow.Fluid inclusion analysis allows discrimination of distinct cement phases,thereby identifying discrete episodes of fluid flow.Ar-Ar dating of the same cements via high spatial resolution laserprobe establishes absolute age constraints on the framework previously constructed.Integration of these two datasets yields temperature-composition-time data.
