Geological setting

Located in the south eastern suburbs of Melbourne, the course is located within the floodplain of Scotchmans Creek, with the creek forming a nasty water hazard adjacent to the 1st, 6th, 7th, 8th and 9th holes.

The course is underlain by some of the oldest rocks in metropolitan Melbourne. These rocks are Silurian age (~420 Mya), and comprise siltstones, mudstones, sandstones and shales. Forming the geological basement of the area, these rocks are kilometres in thickness. The Silurian rocks are shown in grey on the geological plan below.

There was a significant period of no deposition between the Silurian and Cainozoic. During this period, the Silurian rocks were subject to faulting and folding, with a deeply weathered saprolitic profile being developed. Soils forming on the Silurian bedrock typically comprise variable mixtures of silts and clays. Historically, these clays have developed as an extractive industry, e.g. Brickmakers Park. A number of these pits have been identified on the above geological plan to the south of the course (crossed shovel symbol).

Marine and non-marine sediments were deposited in the ancestral topography of the basement rocks. These sediments, differentiated as the Brighton Group, comprise sands, clays and silts. These are shown in yellow on the geological plan.

More recently Quaternary age (<1 Mya) alluvial sediments were deposited within the modern day floodplain. The alluvial sediments include mixtures of sands, clays and silts, and form the playing surface of the course.
