According to Google Maps, You Yangs Regional Park is adjacent to Little River, Balliang and Lara (see figure 1).[CITATION You \l 1033 ]

The major types of rocks in You Yangs Regional Park are igneous, sedimentary and metamorphic rocks. Extrusive igneous rocks formed in Tertiary period are located in the eastern, northeastern and southwestern part while intrusive igneous rocks formed in Devonian period are in the middle part of the park. Most of the non-marine sedimentary rocks formed in Tertiary and Quaternary period are distributed in the middle and southern part of the park. However, marine sedimentary rocks formed in Ordovician and Tertiary period are in the northwestern part of the park. Few metamorphic rocks formed in Devonian period are located in the southwest corner of the You Yangs Granite. According to Bolger (1977), the formation of western bedrock of the Rowsley Fault is due to the deposition of Ordovician clastic sediments in the Ballarat Through. He also stated that “The Ordovician is tightly folded and is capped by widespread laterilized late Tertiary sediments and basalts of the Newer Volcanics.”. In the eastern part of You Yangs, Tertiary marines and non-marine sediments were deposited in the Port Phillip Basin, with widespread plains of Newer Volcanics and Quaternary sediments overlying on them. You Yangs is formed by the upper Devonian granite, which comprises an arcuate ridge of granite spreading south to the Dog Rocks near Geelong. The main minerals in the granite of the You Yangs hills are quartz, alkali feldspar, oligoclase, biotite and hornblende (Skeats,1907). (see Figure 3-1 and Figure 3-2)
