Just a little more than 250 years ago, a Frenchman passed up the Kaw (Kansas) River Valley and made note of the granite and quartzite boulders for what may have been the first recorded notes on the geology of Kansas. Most of the early records were sporadic and not systematically taken. Early expeditions were mainly military; later ones were railroad surveys. Scientists, if on the expeditions, were natural scientists and not geologists, so descriptions usually were of topography, agriculture suitability, transportation feasibility, climate, botany, and other natural phenomena, but seldom of the geology. Documents of these early expeditions, including those of expeditions of Lewis and Clark (1804-6), Pike (1805-7), Long (1819-20), Fremont (1843-45), Emory (1846-47), Stansbury (1849), Marcy (1852), and Beckwith (1853-54) were in a narrative form - long on generalities but short on detail. Thus by the mid-19th century, the geology of Kansas was known only in a general way. The ‘Great American Desert’ was a place to cross, not to stay. The influx of gold seekers and those wanting to exploit the land changed everything and information on the geology became important. To fill the void, ‘guides’ by a variety of self-styled experts on the history, geography, climate, mineral resources, soils, etc., were issued as aids to the emigrants. The guides, usually published by the author, were interesting and popular but included little scientific information. In 1852, David Dale Owen was commissioned a "United States Geologist" and made observations in northeastern Kansas as part of a larger survey. Other geological observations were made by members of early federal government-sponsored territorial surveys of the West. The fossils collected on these surveys and by collectors were described by paleontologists - most reports described the different, new, or spectacular finds. In 1864 the State commissioned the first geological survey headed by B. F. Mudge; the second survey was created in 1865 with G. C. Swallow as State Geologist. Thus the State government assumed responsibility for the surveying - mostly with the idea of making an inventory of economic resources and promoting development of the young state. During the period from creation of the second geological survey in 1865 to the third in 1895, the Kansas Academy of Science Transactions served as one of the leading outlets for information on Kansas geology. The systematic and regular recording of the geology of Kansas commenced in 1895 with creation of the third (and present) State Geological Survey in Lawrence with Erasmus (Daddy) Haworth appointed State Geologist.

The future of coastal resilience or restoration plans which implement natural or nature-based features largely depends upon the identification of proximate and compatible offshore sand and gravel material. BOEM’s Marine Minerals Program (MMP) is multi-faceted, focusing on coordinated leasing of sediment for extraction, inventorying sediment resources through geological and geophysical surveys of the Outer Continental Shelf (OCS), and environmental studies and reviews to inform decisions. However, on a national scale, little is known about the character, quantity, and location of sand resources on the OCS and the habitat it provides for biological communities. BOEM places a high priority on creating a comprehensive national sand resource inventory to meet BOEM’s mandate as stewards of all federal mineral resources on the OCS. This stewardship responsibility will be realized by proactively planning for the increasing demands for OCS resources and emergency needs as they arise.

Petroleum exploration of the Ngalia Basin commenced with the Pacific-American Oil Company's seismic and gravity survey in 1964, followed by geological and geophysical surveys by the Bureau of Mineral Resources (BMR) between 1967 and 1978, and then Magellan's Ngalia seismic and gravity survey in 1971.After a ten year break, exploration resumed with the drilling of the Davis-1 well by a consortium of Australian companies which farmed-in to Magellan's Ngalia Basin Permit (OP165). The well was drilled on the flank of a large east-west trending anticlinal dome outlined by surface mapping and limited seismic coverage, and located near the northern margin of the basin. The section penetrated in the well consists of 1134 m of Carboniferous-Devonian sediments unconformably overlying 479 m of probable Cambro-Ordovician marine sediments, which in turn unconformably overlie approximately 246 m of marine ?Adelaidean sediments, including a basal sequence of dark grey marine shale. Source rock analysis indicates that this latter section may provide a significant source rock potential for the basin. A small gas flow was observed during the course of the well, which was air-drilled to a total depth of 1899 m, bottoming in metamorphics which are tentatively correlated with the Pre-Cambrian Patmungala Beds (?Arunta Block). The current exploration effort is now aimed at:more deeply buried structures in the Naburula Fault Trough, in the western half of the basin, andsub-surface extensions of the Walbiri-Bloodwood Fold Zone, in the eastern half.In both cases a more extensive section of marine Cambro-Ordovician age rocks is anticipated, and the limited geochemical data available suggest that these sediments should lie within the oil window.The Newhaven-Mt Allan Seismic Survey, consisting of 344 km of 12-fold vibroseis coverage was shot in these areas in November-December, 1981, in an attempt to define prospects and leads for evaluation by additional drilling over the next three years. The structures mapped to date include reverse faulted blocks with salt-involvement in the Newhaven area to the west, and "sled-runner" thrusts with a plane of décollement in salt in the Mt Allan area to the east.

The Canning Basin in northern Western Australia is a large, relatively remote, mainly desert-covered Phanerozoic basin covering 595 000 sq km. Aborigines probably first entered the basin area 30-40 000 years ago, but the main European expeditions were not until the nineteenth and twentieth centuries. Geological exploration in the basin has been largely devoted to the discovery and exploitation of natural resources, primarily oil. Earliest geological traverses were conducted by geologists of the Geological Survey of Western Australia (GSWA). The accidental discovery of traces of oil in a water well in 1919 in the northern part of the basin diverted exploration to assessment of sediments and structures for petroleum potential. The earliest phase of oil exploration was a pioneering phase, concentrating on surface mapping and surface delineated structures as drilling sites, that was dominated by the Freney Kimberley Oil Company. West Australia Petroleum Ltd became the most active oil exploration company in the 1950s, 1960s and 1970s, using geophysics as an exploration tool in petroleum search in the basin. The late 1970s and 1980s saw an influx of companies and the application of diverse scientific approaches to the oil search. Persistence was rewarded in 1981 and 1982 with the discovery of the Blina and Sundown fields, small commercial oil accumulations. Commonwealth Government involvement in exploration was initially in the form of financial aid to exploring companies or commissioning specialist consultants for special studies. In the 1940s and 1950s and again in the 1970s the Bureau of Mineral Resources carried out basin-wide regional geological mapping in conjunction with the GSWA; onshore and offshore geophysical surveys were conducted until the 1970s. Exploration has revealed exploitable resources in the basin besides oil - diamonds, lead-zinc, coal, salt, phosphate, uranium, and heavy minerals. Only lead-zinc has present economic viability.
