...-scale décollement within the Lower Yangtze foreland fold-thrust zone. The ductile fabrics exposed in the Zhangbaling–Feidong Complex of the southern Tan-Lu fault zone record the strain that accumulated during that collision. Herein, field observations and structural analysis of high-strain rocks (i.e...

... of magnetic susceptibility (AMS) fabrics as proxies for silicate petrofabrics. Mineral lamination is a relatively common structural feature in cumulate rocks, including in the Ilímaussaq intrusion, but there is little consensus on the process (or processes) responsible for its formation. The Ilímaussaq AMS...

... susceptibility (AMS) results displayed both normal and reverse fabrics for the sampled outcropping formations. To interpret the reverse magnetic fabrics, we performed Anisotropy of Anhysteretic Remanent Magnetization measurements to define their normal configuration. Both magnetic methods showed well-defined...

...Ben Latimer; William McCarthy; Tobias Mattsson; John Reavy Abstract Mineral fabrics within igneous intrusions can archive both tectonic and magmatic processes. However, whether magmatic state fabrics reflect primary magmatic processes or regional tectonic strain is often ambiguous. To investigate...
