NBMG’s Geologic Mapping Presence in the World – OneGeology

This week is Earth Science Week and the theme for the week is “Mapping Our World.” NBMG celebrates the week with two new geologic maps (see previous post) and an update on NBMG’s participation in the OneGeology project.


“OneGeology is an international initiative of the geological surveys of the world. This ground-breaking project was launched in 2007 and contributed to the ‘International Year of Planet Earth’, becoming one of their flagship projects.

Thanks to the enthusiasm and support of participating nations, the initiative has progressed rapidly towards its target – creating dynamic geological map data of the world, available to everyone via the web. We invite you to explore the website and view the maps in the OneGeology Portal.” (from OneGeology website)

The Nevada Bureau of Mines and Geology holds a record: we have added our STATEMAP digital conversions to the OneGeology website (http://www.onegeology.org/ ), and currently NBMG has more features than any other country in the world. Access the world map through the OneGeology portal (http://portal.onegeology.org/)

With the efforts of Kathryn Ryan, Gary Johnson, Lisa Shevenell, and Selena Large, we have added 27 feature groups (map scale groups). United Kingdom comes in second with 26 feature groups. NBMG has added the various scales of geologic mapping from 1:500,000-scale (Stewart and Carlson 1:500K) up to 1:12,000-scale maps. This effort reflects over 200 geologic maps that are represented by age of the geologic unit. The data is represented in each scale by features of contacts, faults, and geologic units. There is much more to be added, and as time and funds allow, we will update. OneGeology runs a little slow, but the information represented is valuable.
