W. Dan Hausel

Prior to 1977, only jade, a couple of microdiamonds, agate and jasper were known in Wyoming. Following his instincts, author Dan Hausel found hundreds of diamond, ruby, sapphire, iolite, gold and other gemstone deposits including idenfied the largest colored gemstones in the world and found additional deposits of gem garnet, chromian diopside, Cape Ruby, Cape Emerald, some aquamarine, peridot, and giant opals. Wyoming is now know to be gemstone rich due to the work of the author. In additon, the author found several minerals that were previously unknown in the state as well as some unusual rock types. Possibly no other person influenced the geology of Wyoming more than Professor Hausel.

The Leucite Hills are a relatively recent volcanic field north of Rock Springs. The lavas are known as lamproites, possibly the rarest rock type on earth. Elsewhere on the earth, where olivine lamproites are found, they almost always contain diamond, thus the author set out to map this volcanic field and search for gemstones. He found the first reported occurrene of peridot (gem-olivine) in the state and proposes that the area has good potential for discovery of diamond deposits.

Geology of the Iron Mountain Kimberlite District. Describes kimberlite discoveries, diamonds and possibilities for additional discoveries. Contains detailed geological map. The author investigated this kimberlite district (the second largest kimberlite district in the US) as a mapping project and found it to represent a classical, deeply eroded, dike-blow complex. The geochemistry of the kimberlites suggest that all should contain diamonds - to date, one 0.3 carat diamond was recovered from very limited sampling.

Describes essentially every gemstone and unique mineral and rock locality in Wyoming giving legal descriptions of locations where known. This is a field guide as well as reference to a few hundred localities in the state including dozens of new localities of gemstones that were discovered by the senior author.

Book describes many of the great diamond finds throughout the US. Focuses on diamond deposits in the Wyoming Craton - Wyoming, Colorado, Montana. This book is the authority on diamonds and their host rocks found in the United States.

Describes base and precious metal deposits in Wyoming including legal descriptions, geology, mineralization, associated metals and any production. Most of the deposits were visited and mapped by the author.

Self-guided tour to the geology and mineral deposits along the Snowy Range scenic highway. The stops include old mines, possible diamond deposits and a location where one can see geological evidence of global warming and global freezing more than 2 billion years ago.

South Pass is Wyoming's primary source for gold and iron ore and represents a classical greenstone belt that has been intensely folded and faulted. The author spent 6 years mapping this complex terrain and found more than 100 gold anomalies as well as the tectonic control for ore shoots. In recent years, this terrain has become a popular place to search for gold deposits. The book was published prior the the WGS providing ISBN numbers, but has remained one of the more popular books at the Wyoming Geological Survey. It is available at the WGS publications section.

This book describes nearly every known gold, silver, platinum and palladium occurrence and mine in Wyoming. An extensive work on precious metals in this state. The book was published prior the the WGS providing ISBN numbers, but has remained one of the more popular books at the Wyoming Geological Survey. It is available at the WGS publications section.

W. Dan Hausel, the most productive geologist in the history of the Wyoming Geological Survey examines the State's mineral deposits. This book is an excellent descriptive publication on the state's minerals and rocks and includes discussions on minerals that were previously unknown in Wyoming until discovered by Hausel. Some of the interesting minerals and rocks described in the book include ruby, sapphire, diamond, iolite, peridot, opal, kimberlite, lamproite, komatiite, and more.

This book was published prior the the WGS providing ISBN numbers. It is available at the WGS publications section. The Copper Mountain district is a high-grade metamorphic terrain that was prospecting for copper, gold, silver, rare earth metals, lithium, and aquamarine.

The book was published prior the the WGS providing ISBN numbers. It is available at the WGS publications section. The book provides information on diamond extraction and geology of the State Line diamond district.

The book was published prior the the WGS providing ISBN numbers. It is available at the WGS publications section.

The book was published prior the the WGS providing ISBN numbers. It is available at the WGS publications section. The publication describes geophysical and geological methods that were used to successfully find kimberlite in the Colorado-Wyoming State Line district where more than 130,000 diamonds were found from 1975 to 1997.

The book was published prior the the WGS providing ISBN numbers. It is available at the WGS publications section.

Chinese Cantonese edition of the leading guide to diamonds, providing the reader with an essential knowledge of diamonds and an understanding of the main factors that determine their value and quality. Includes a special chapter on natural colour diamonds and is richly illustrated throughout.

Erlich and Hausel are two of the leading diamond geologists in the world - Dr. Erlich brings his expertise from the former Soviet Union and Professor Hausel his knowledge of diamond deposits in North America and Australia.
