| Site: MM652 | Land Unit: Warrabkook Basalts |
| Aust. Soil Class.: Ferric, ?, Brown KUROSOL (confidence level 3) | |
| General Land Unit Description: This land unit consists of gently undulating basalt plains in the Macarthur area. In some drainage lines, the basalt has been dissected sufficiently to expose the underlying sediments. The soils on the basalt plains are commonly Brown Kurosols or Chormosols, intermixed with Sodosols, particularly on the lower slopes and drainage depressions. |
