1. North Stradbroke Island

A self guided tour of North Stradbroke Island is included as a download for your trip to the island and includes the ferry trip from Victoria Point across Moreton Bay to Dunwich. The geological processes in this region cover a period of earth history of at least 300 million years  Exposed rock outcrop occurs at Dunwich, at low tide adjacent to Canaipa Point opposite Russell Island and on the northeastern tip of the island adjacent to Point Lookout.  This rock exposure is of metamorphosed augite greensttone interpreted as part pf the basement rocks of the North D’Aguilar block and considered to represent sea floor basaltic volcanics of late Devonian age (about 300 million years before the present.

North Stradbroke Island proper  is dominantly quartz sand with economic concentrations of heavy mineral sand that has been mined and progressively rehabilitated after mining.  It also has a diversity of vegetation and wildlife that has developed over a period of about a million years.  The island developed  through  the movement of quartz sand from erosion of granitic rocks in northern New South Wales and northern movement by ocean currents. A series of parabolic dunes with northeast directed blowout orientations were created by strong south-easterly prevailing winds.   The island has a resource of fresh water that is tapped for onshore use by Redland Shire Council. The largest lakes on the island are a ground water lake that is a window into the regional water table (Blue Lake) and Brown Lake a perched water table lake with a underlying layer of organic sand rock.

The landscapes of the coastal area of Esperence are characterised by some of the whitest sands and darkest blue water of the Australian mainland.  The Granite pictured here is geologically an old one dating back to the Proterozoiz (more than 1500my BP).

A compilation of sites in Google linked to Global tourism and /or Geohistory tourism links to one of the three component of what is termed geohistory tourism in this site – geology, landscapes and resources, Ecotourism and Cultural/human history tourism.

Examples  of some of these sites is given below under which of these categories the main focus is linked.
