ConclusionsConclusions

Three shale gas exploration fairways have been identifiedin the Utica / Lorraine sequence of the St. Lawrence Lowlands :

Shallow platform, biogenic/thermogenic playDeep platform, thermogenic playDeep thrusts, thermogenic play

A fourth exploration fairway pertaining mainly to the LorraineGroup is present in the southern part of the Lowlands, beingpossibly related to the reactivation of E-W transform or normalfaults originally formed during the Cambrian rifting of Laurentia

Additional results are expected shortly, especially from thedeeper, TOC-rich thrust sheets;Visit our website at http: // sigpeg.mrnf.gouv.qc.ca
