The orientation and spatial distribution of veins in the Lockport dolostone attest to a fluid circulation system active during the Acadian orogeny in western New York and southern Ontario. Outcrops east of the Clarendon-Linden fault zone are cut by a prominent east-northeast systematic calcite-filled vein set, whereas these systematic veins are absent west of the fault zone, except in two quarries. Maximum horizontal stress (S
H
) trend lines drawn parallel to the strike of the systematic veins are incompatible with S
H
inferred from Alleghanian plateau and other post-Paleozoic structures. However, because east-west S
H
trend lines are compatible with an Acadian tectonic event in western New England, systematic veins in the Lockport Group are a cratonward signature of the Acadian orogeny. -from Authors
