Geological map of the Hunter River Valley between Greta and Muswellbrook, ca. 1928 (Item 1)

The map explores the geology of Muswellbrook and the Hunter Valley region. The map illustrates the geological periods: Post-Tertiary; Triassic; Permian; Carboniferous; Tertiary. The Permian period in chronical sequence shows sedimentary rocks beginning at the lower marine series, followed by the Greta Coal Measures, and Upper Marine Series which include: Branxton Stage, Muree State and Crinoidal Stage, with the final the Upper Coal Measures. The Tertiary period contains Igneous rock, namely Basalt (intrusive and extrusive) as well as Sills - mainly Alkaline Dolerite. The Map also features a locality map and the sites proximity relative to G.N. Railway within New South Wales.On sheet 64cm x 64.5cm.

Geological map of the Carboniferous System between Glennies Creek and Muscle Creek, Hunter River District, ca. 1928 (Item 2)

The map explores the geology of Glennies Creek and Muscle Creek of the Hunter River District in New South Wales.

The map illustrates the geological periods in order (youngest to oldest): Post-Tertiary; Permian; Carboniferous. The Post Tertiary shows Alluvium, while Permian period shows Coal Measures and Marine Sediments. The Carboniferous period into two geological processes: Glacial Stage and Volcanic Stage. In the Glacial Stage the map illustrates both Glacial Beds and coarse glacial conglomerate as well tuff; while the Volcanic Stage is illustrated by course conglomerate and tuffs, Horneblende Andesite, Dacites and glassy and lithoidal, Andesitic tuff, Felsitic lavas of various kinds and Pyroxene Andesite.

Geological map showing the Structural Relations of the Carboniferous and Permian Rocks in the Hunter River Valley, NSW, 1928 (Item 3)

The Map explores the geology of the Hunter River Valley in New South Wales. The map illustrates the following geological periods in order of youngest to oldest: Post-Tertiary; Triassic; Permian; carboniferous. The Post Tertiary shows Alluvium, while Triassic shows Sandstones. The Permian period shows: upper Coal Measures, upper marine series, the Greta Coal Measures, and Lower Marine Series. The Carboniferous period details the Kuttung Series which include: Toscanite, Felsite and Andesite, followed by the Burindi Series (no further detail).

The map is annotated with the following explanatory note, copied verbatim: The sources of the geological information shown on this map are as follow:- The detail of the Carboniferous geology is the result of the work of the author, except for the area between the Webbers CK. Fault and Lams Creek, the area east of Limeburners Creek near Port Stephens, the inliers south-west of Maitland, and an area of about 35sq miles surrounding the Village of Gosforth, the last of which has been described by Prof. Browne, (1926). The detail in the Permian region is chiefly from the map accompanying Prof. David's Memoir on the Hunter Coalfield (1904), and also from maps published more recently by the Geological Survey of N.S.W.On sheet 146cm x 62cm.

Geological map of the Carboniferous System between the Raymond Terrace - Clarencetown District and the Scone District, Hunter River Valley, NSW, 1928 (Item 4)

Map illustrating the geology of the Raymond Terrace, Clarencetown and the Scone Districts in Hunter River Valley region, New South Wales. Map illustrates the geological periods: Post-Tertiary, Permian and Carboniferous for the Hunter Valley region. The Carboniferous period features both the Kuttung Series and Burindi Series. The Kuttung series conveys various formation stages including: a glacial, volcanic and Basal stage. The Burindi Series shows Marine sediments, along side faults, and outliers of Tertiary basalt and Permian sediments. On sheet 220cm x 65cm.
