 | | The objectives of the Talkeetna Mountains transect project are: (1) to identify the mineral deposit types occurring within each lithotectonic terrane, (2) to define, including timing and orientation, the structural relationships between major terranes (Kahiltna, Wrangellia and Peninsular), (3) to determine any stratigraphic or subsequent metamorphic, magmatic or structural ties between the smaller "micro-terranes" (e.g. |
 | | Detailed observations (1:63,3600 and larger) of structures, stratigraphy and geology will be made within the Iron Creek tract and at specific mineral occurrences (with DGGS, UAF) and in Tertiary volcanic rocks across the KWP area (by Allegheny Univ., UAA, UAF). |
 | | Stratigraphic and lithogeochemical studies, structural mapping and ground magnetic, gravity, and audiomagnetotelluric surveys will be combined with isotopic and paleontologic age dating along a 20 x 100km transect (1:125,000 scale, Talkeetna transect) linking the Iron Creek and Chulitna aeromag tracts. |
