Quartzsite, Arizona, barely 18 miles east of the Colorado river, on I-10, may be the RV boondocking capital of the world. Quartzsite has become a mecca to visitors and exhibitors for rocks, gems, mineral specimens and fossils during the towns famous two-month-long gem show and swap meet every January and February.

What is Shale? Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as "mudstones." Shale is distinguished from other mudstones because it is fissile and laminated.
What are Minerals? To meet the definition of "mineral" used by most geologists, a substance must meet five requirements: naturally occurring; inorganic
Abutment In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment,
Rock types! If you are not sure what kind of rocks are near you, the first thing to do is contact your state Geological Survey. You can order geologic maps of almost anywhere in
Rockhounding Georgia. Georgia is a good state for rockhounding.
See What's New at the Maine Geological Survey. See recently released publications, maps and digital data. Read news updates on MGS announcements, awards and job openings. Find out what MGS staff have been doing for speaking engagements, research and outreach efforts.
The rocks and minerals described in this booklet can be found in Maine. Some are very plentiful while others are hard to find. Chebeague Island's K-3 graders have been studying rocks and minerals this year and decided it would be nice to have their own Maine Rocks and Minerals Book.

Available Elements. Since the ^chemical elements are the fundamental building blocks of all ordinary materials, including minerals, let's start there. Elemental abundances at and near the surface of the earth tightly constrain the range of minerals and rocks observed, not to mention the range of possible biologic processes.
When it comes to the composition of the Earth, three main types of rock come into play. These are known as metamorphic rock, sedimentary rock, and igneous rock, respectively.

Rocks are composed of grains of minerals, which are homogeneous solids formed from a chemical compound arranged in an orderly manner. The aggregate minerals forming the rock are held together by chemical bonds.
