The intrusive has been variably altered, structurally imbricated and hydrothermally altered by syn and post intrusive tectonic and hydrothermal activity related to Eocene west side north dextral transtensional activity. Within many of the tensional structures highly compositionally variable dykes were emplaced. In the case of TOP most if not all dykes display deformation and truncation by syn and post intrusive displacement. Synchronously associated with a mafic to andesitic dyke suite are the following suite of alteration and mineralization minerals.
