This map is part of a series which comprises 50 maps which covers the whole of Australia at a scale of 1:1 000 000 (1cm on a map represents 10km on the ground). Each standard map covers an area of 6 degrees longitude by 4 degrees latitude or about 590 kilometres east to west and about 440 kilometres from north to south. These maps depict natural and constructed features including transport infrastructure (roads, railway airports), hydrography, contours, hypsometric and bathymetric layers, localities and some administrative boundaries, making this a useful general reference map.

Mount Marumba covers the central part of Arnhem Land, which is occupied mainly by the Katherine River, Mount Rigg and Roper Groups of the Palaeoproterozoic to Mesoproterozoic McArthur Basin succession. These units consist of marine and non-marine clastics, carbonates, and lesser volcanics, that are extensively intruded by dolerite and some microgranite. Recent mapping and associated structural, geophysical, geochemical and geochronological studies has led to a number of important results, including: (a) the Jimbu Microgranite intruded the Katherine River Group at ~1710 Ma, causing updoming of surrounding sediments to form a number of structural domes; (b) the former Kombolgie Formation has been elevated to a Subgroup, subdivded into component formations, and extended upwards to include the McKay Sandstone; and (c) the Gulpuliyul Structure, a major impact structure formed between ~1600 and 1324 Ma, was recognized 45 km NW of Bulman. The mapping and interpretation took advantage of the full complement of regional gravity, airborne magnetic and gamma-ray spectometric datasets now available. Concealed dykes, lineaments and sill edges are overprinted on the surface geology in magenta. In addition, the map features 1:1 000 000-scale marginal figures of an enhanced total magnetic intensity image and a gamma-ray spectroscopy image. A 1:3 000 000-scale marginal map provides the regional setting. Two cross-sections highlight the salient features of the stratigraphy and structure.

The map covers an area of 0.850 degrees longitude by 0.883 degrees latitude or about 76 kilometres from east to west and about 96 kilometres from north to south. At this scale 1cm on the map represents 1km on the ground. This map contains natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 20m), localities and administrative boundaries, such as national parks, and nature reserves. The reverse side of the map depicts the same area using an orthophoto mosaic.
