Public Information Circulars
These circulars address the issues concerning geology. A complete list of Public Information Circulars (PIC) is available on the Publications Index Page.
- Kansas Geologic Maps
- This online version of PIC 38 describes how geologic maps are made and how they are used.
- Sand, Gravel, and Crushed Stone: Their Production and Use in Kansas
- PIC 6 discusses sand, gravel, crushed stone, and lightweight aggregate, a man-made material manufactured from shale. This publication describes the type and amount of these materials used in Kansas; their source, processing, and usage; and environmental issues related to their production.
- Landslides in Kansas
- This web version of PIC 13 provides property owners, government officials, and developers an introduction to landslides in Kansas and outlines common approaches for their remediation.
- Kansas Kimberlites
- PIC 16 provides general information about these rare and unusual rocks found in the heartland of the United States.
- Lead and Zinc Mining in Kansas
- This circular explains the history and geology of the Tri-State mining district in Kansas, the environmental consequences of lead and zinc mining, and efforts to solve some of these problems and reclaim the land.
- Salt in Kansas
- Salt is an abundant and valuable natural resource in Kansas. In addition to salt's well-known uses (such as table salt or road de-icing material), large caverns dissolved out of salt beds also are used to store natural gas, natural gas liquids (such as propane and butane), and other petroleum products.
- Invertebrate Fossils of Kansas
- Anyone who has spent much time outdoors in Kansas probably has encountered a fossil or two. Kansas rocks are full of fossils. From shell fragments in a chunk of gravel to spectacular specimens in museum displays, Kansas fossils contain important evidence about the history of life on earth.
