2 CB1 Moderately undulating landscape with slight gilgai (few inches) formation: broad ridge tops and upper slopes of moderately shallow grey cracking clays (Ug5.22 and Ug5.23). Associated are: (i) some dark cracking clays (Ug5.13); (ii) various alkaline (D) soils, such as (Db1.43) and (Dd1.33); and (iii) in the lower-lying situations deeper grey cracking clays (Ug5.25 and Ug5.24) with small areas of (Dy3.43) soils. As mapped, small areas of units HG3 and Kb6 are included in some localities. Occurs on sheet(s): 3,4 CC17 Plains of slightly gilgaied (few inches) cracking clays associated with major and minor functional and nonfunctional drainage-ways: chief soils are grey clays (Ug5.24 and Ug5.25) and brown clays (Ug5.34 and Ug5.35). Associated features and soils are: (i) many small low domes or rises (often levee banks) related to old drainage-ways, with soils of units B10, Si2, and R03 north of about the CollarenebriMoree line (Sheet 3) and of unit Oc12 south of about this line--note that these low domes may give rise to apparent toposequences of soils locally; (ii) small areas of (Dd1.33) and (Dd1.43) soils along the eastern margins of this unit; (iii) some areas of dark clays (Ug5.15 and Ug5.16), especially in the Moree-Narrabri localities (Sheet 3) and possibly related to adjacent elevated basalt areas; (iv) some undescribed (?U) soils on recent terraces and flood-plains along some present streams; (v) some repeatedly flooded areas with grey clays (Ug5.5) having a massive surface; and (vi) some swamps and mar. Occurs on sheet(s): 3,4 CC20 Gently undulating cracking clay plains with moderate to strong (2 4 ft) gilgai microrelief: chief soils are deep grey clays (Ug5.24) with smaller areas of (Ug5.25) and (Ug5.28) and some brown clays (Ug5.34). Soil reaction values of these cracking clays vary and comprise: (i) alkaline or neutral surfaces with acid subsoils (common); (ii) acid throughout (fairly common); and (iii) alkaline throughout (rare). In some areas (Dy2.33) and (Dy2.43) soils occur on the slightly raised flat areas between gilgai depressions or adjacent to small drainage-lines. As mapped, small areas of units B10, MM1, and Ro4 are included in Queensland, and unit Ro1 in the Narrabri area of New South Wales (Sheet 3). Occurs on sheet(s): 3,4 Cb30 Rugged granitic areas with rock walls and tors: chief soils are leached sands (Uc2.3), notably (Uc2.34) and (Uc2.31) with various shallow sand soils such as (Uc4.1) and (Uc1.21). Associated are soils common to unit Wa10 especially in areas of more subdued relief; (Dy3) soils, such as (Dy3.62), often with large amounts of ironstone gravel, especially on undulating ridge tops (?plateau remnants); (Dr2.21) soils on areas of dark intrusive rocks; occasionally soils of unit Rh5; and some of the wetter portions which may approach unit Mw4 in character. KK5 Plateau remnants at high elevation (>4500 ft), rock outcrops: organic loamy soils (Um7.11) in the moister sites with (Um5) or (Gn2) soils in the drier sites. Small area. Data are limited.

Kc2 Dissected basaltic plateau: undulating terrain of dark cracking clays (Ug5.13) and (Ug5.15) in association with (Db3.12) and/or (Dr4.12) soils, often on the stony areas. Data are limited. Kc3 Dissected basaltic plateau--strongly rolling to hilly with some steep, broken slopes, bouldery: chief soils are dark cracking clays, principally (Ug5.13, Ug5.14, and Ug5.15). The associated soils are not known but are likely to include those recorded for unit Kc4 and, less commonly, soils of unit Ms1. Kc4 Dissected basaltic plateau with hills and flat-topped ridges, sometimes bouldery: gently rolling to rolling terrain of dark cracking clays, principally (Ug5.13, Ug5.14, and Ug5.15)and red-brown cracking clays (Ug5.37 and Ug5.38). Associated are (Um6.2), (Db3.12), and (Ug5.12) soils on hills, knolls, and ridges; and small areas of (Gn3.12) and (Gn2.11) soils, especially towards the boundary with unit Mo7. As mapped, areas of unit Kc3 may be included. Kc5

Kc6 Undulating to hilly with some steep slopes, bouldery in places: chief soils are cracking clays (Ug5.13), (Ug5.15), and (Ug5.3) with red friable earths (Gn3.]2) and sometimes red earths (Gn2.1). Some variations exist between individual occurrences: this unit has similarities with units Kc4 and Mo7. Occurs on sheet(s): 3 Kd4 Valley plains of dark cracking clays (Ug5.15 and Ug5.16).
