Abstract
In the Goodmans Ford‐Bullio area NSW an adamellite granodiorite pluton and several small previously undocumented tonalite plutons hosting orbicular xenoliths, are intruded into dacitic ash flows and rhyodaeitic lavas of the northern part of the Early Devonian Bindook Volcanic Complex. These plutons are shown to be satellite plutons of the Early Devonian Marulan Batholith and have been passively emplaced along fractures or faults in the host volcanics by collapse of the roof volcanics, possibly following magma withdrawal during eruption. Reconnaissance fieldwork indicates substantial volumes of intrusive rocks to the north and west of the Goodmans Ford‐Bullio area. A comagmatic relationship between the Bindook Volcanic Complex and the Marulan Batholith, suggested by their close spatial and temporal association, is supported by petrological and chemical data.
