This year marks the 130th anniversary of the establishment of the Geological Survey of Western Australia (GSWA). This endeavour was initially resisted by members of the Legislative Council, who ‘…denied scientific men had contributed in any way to the important mineral discoveries which had made the fortunes of the other colonies’ and wondered ‘…what good had any geologist ever done to Western Australia?’ But the role played by the geological observations and maps of ET Hardman in the Kimberley gold discoveries and subsequent rush eventually led the Council to approve the establishment of a new, permanent Geological Department with a subsidy of £1000.
The permanent* position of Government Geologist was taken up in January 1888 by HP Woodward. Since then, there have been 12 Government Geologists, and the position’s formal name was changed to Director of the Geological Survey during Joe Lord’s tenure.
Over the years, the men invested with this responsibility have ensured that GSWA remains faithful to the ‘dual objectives of practical, field-based research and the provision of solid, unbiased geoscientific advice to government, industry and the public’ (Phil Playford, GSWA Memoir 3). Whether with camels and horses or a fleet of GPS-tracked vehicles, fieldwork has been a staple of GSWA since its very beginning. Mapping of the State has evolved from regional expeditions looking for ‘riches’ in the early days of the Colony to systematic mapping at 1:250 000 (completed in 1979) or 1:100 000 scale. The focus is now shifting from rectilinear map sheets to mapping of tectonic units or to address specific geological questions.
Starting in the 1990s, digital technology has greatly impacted the way GSWA compiles and produces maps and manuscripts, as well as how it delivers data and information. A far cry from the days of theodolites, plane-tables and glass-plate negatives, modern fieldwork makes use of tablet PCs that allow the immediate capture of field observations in a GIS environment, where the data can be assessed against remote sensing imagery. Drones are now used to map otherwise inaccessible outcrops or those containing geological objects too large for the geologist to map in the field but not large enough to be resolved in aerial and satellite imagery or geophysical datasets. RPA imagery provides the ‘bigger picture’ while keeping the very fine detail.
Accelerating technological advances have not only changed the way we work, but have greatly enhanced the contribution of GSWA geologists to unravelling the geological framework of the State, particularly in the last half century. The introduction of modern aerial photography and aeromagnetic images in the 1970s and 1980s, the routine use of geochronology and geochemistry from the 1990s, the acquisition of seismic profiles and passive seismic data as well as the introduction of isotope geochemistry in the last 20 years are culminating in the development of 3D and 4D geomodels that provide an integrated view of the tectonic evolution of Western Australia.
Datasets acquired by GSWA (often in collaboration with other national and state institutions) have grown in quantity and size over time, as have the number and volume of legislation-mandated exploration reports from the minerals and petroleum industry. To be true to its mission of being the lead agency for the provision of geological information in the State, in the late 1990s GSWA embarked on a two-fold program: legacy data capture via a scanning and digitizing program, and the development of novel ways to distribute information via digital platforms. As a result, customers can now access well over 6000 publications via the eBookshop and download large digital datasets from the Data and Software centre. GeoVIEW.WA was developed as an online GIS-based mapping tool that allows simultaneous viewing and querying of multiple datasets; a freely available standalone equivalent, GeoMap.WA, and the WA Geology mapping app offer the same functionality. The quality of GSWA’s databases and systems has been consistently recognized with high ranking in the international Fraser Institute Annual Survey of Mining Companies.
GSWA’s delivery of data and information does not stop at the digital doorstep. The core libraries built in Kalgoorlie and Perth house about 1400 km of drillcore, a physical asset designed to assist exploration activity in the State. Access to physical drillcore is complemented by the acquisition of HyLogger spectral scans delivered via GeoVIEW.WA and the National Virtual Core Library. Digital core atlases are a new and innovative product that offers an interactive display of multiple datasets overlain and linked to images of individual core trays. Additional drillcore is regularly acquired through the Exploration Incentive Scheme (EIS), a State Government initiative managed by GSWA. Started in April 2009, the EIS programs of drilling promotion, geophysical data acquisition and 3D prospectivity mapping are designed to add vitality to the State’s mineral and petroleum exploration industry.
The life of GSWA has not been without challenges. Structural changes (e.g. the loss of the Hydrogeology section in 1996), the migration of geologists to better paid jobs in times of industry boom in the nickel and mining boom of the 1970s and 2000s, and funding insecurity have all been weathered through the dedication and commitment of GSWA’s directors and staff, as well as the love of GSWA’s geologists for the rocks in their immense backyard, and their loyalty to a beloved organization.

There are three virtual tours in this series of GSWA products and more to come. They are simulations of existing locations on a map that users can follow while in the Google Earth application.
State meteorite impact structures is aimed at amateur geologists and anyone wanting more information about these impact structures. Wolfe Creek is probably our most famous impact structure!
Discovery trails to early Earth allows users to visit various element of six discovery trails across the east Pilbara, centred on Marble Bar.
Mafic–ultramafic intrusions of the Youanmi Terrane is a virtual field excursion for the experienced geologist. Each field site can be viewed in turn, or separately, and is supplemented by high-quality figures, images and illustrations that can be opened in a separate browser without detracting from the site information.
