"This study describes the geological framework for a series of in the northwest part of the St. Cyr area, west of the South Canol Road, in south-central Yukon. The layers of rocks include metamorphic rocks including a higher temperature mafic-ultramafic package and lower temperature packages including phyllite, marble and limestone. Relationships between a number of rock units in the field suggest the rocks were originally formed in an oceanic setting. U-Pb geochronology using zircons confirm the ages for a number of the rock units. These rock units were subsequently faulted into their current location"--Provided by publisher. gccst Igneous rocks gccst Metamorphic rocks gccst Geochronology gccst Petrology gccst Structural geology Isard, Sierra J.
