Online_Linkage: https://doi.org/10.14509/31108 Description: Abstract: Preliminary description and interpretation of the Doone Creek fault and associated structures: The potential offset and northeastward continuation of the Bruin Bay fault system in the south-central Talkeetna Mountains, Alaska, Preliminary Interpretive Report 2024-1, provides station location data and fault and bedding plane dip angle measurements collected during reconnaissance field mapping in the southern Talkeetna Mountains. This publication discusses structural observations and presents a preliminary 1:25,000 scale geologic map of the Doone Creek area, southcentral Talkeetna Mountains. The map area encompasses the junction between the Castle Mountain and Caribou faults that cut obliquely across the Jurassic Talkeetna arc. The area also contains the newly identified Doone Creek fault and an intra-formational brittle fault zone that deform Talkeetna arc lithologies subparallel to the arc boundary. The Doone Creek fault and other north and northeast-trending faults and folds represent an unstudied family of structures that may be correlative to similar features that bound the southeastern margin of the Talkeetna arc in the Cook Inlet area to the southwest. These data and report are available from the DGGS website: http://doi.org/10.14509/31108. Purpose: This publication provides observations and discussion of the nature and significance of faults that deform the Jurassic arc-forearc margin in the Talkeetna Mountains.
