Laxford shear zone

WebThis paper reviews the geology of the Laxford Shear Zone, clarifying field relationships and discussing other evidence, to consider whether or not it does indeed represent a terrane boundary. A detailed review of field, geochemical and geochronological evidence supports the recognition of the separate Assynt and Rhiconich terranes. WebOne of these granite sheets has been dated at c.1855 Ma (Friend and Kinny, 2001); these are Laxfordian granites, similar to those seen on the south side of the Laxford Shear …
