282 | Beekit, alternate spelling of Beekite? |
283 | Beekite, usually white, opaque silica that appears in the form of spherical, discoid, rosette, doughnut or botryoidal accretions. The material generally appears as bands or layers and is commonly found on partially to fully silicified fossils. The American Geological Institute Glossary of Geologic Terms suggests that the material is commonly found on the surface of silicified fossils or on joint surfaces as a replacement of organic matter. Large beekite accretions appear on the surfaces of many agates and are not commonly associated with organic matter. The term has also been used for chalcedony that is pseudomorphous after coral, brachiopod, and clam shells and has been observed on numerous crinoid ossicles. Beekite forms a kind of eye agate that is commonly observed in material from Brazil and loose Beekite growths may be referred to as Conchas, which see.The term may also be used to refer to similar growth of calcite. Sinkankas (1959, p. 308) called it a silicified coral....agatized honey-comb coral, adv., A. L. Thomas & Sons, Oregon Mineralogist, v. 2, no. 6, p.

375 | Blue Agate Geodes, Chihuahua, Mexico, (Keller, 1977, p. 99-108) described geode occurrences in the Sierra del Gallego Mountains, Chihuahua, and suggested the chalcedony rinds were less colorful than the agate nodules in this area because there were fewer iron compounds in the geode bearing rocks. Many of the geodes from this area have a bluish (blue-gray) layered chalcedony shell. Cross (1996, p. 62, 63, pl. 19) illustrated a blue agate that he suggested originated as thunder egg cores, but these are distinct entities from what Keller described. |

382 | Blue Chalcedony, Nebraska, South Dakota, Zeitner, J. C., 1960. Rare Gems of the Midwest, Earth Science, v. 13, no. 2, p. 58-62. Pabian (1971, p. 58, 59, frontispiece, pl. II, fig. 6; pl. 3, figs. 3, 4; pl. 4, figs. 1, 2) used this term to apply to chalcedony that has formed in place in joint systems in wind-blown siltstones that make up much of the lower Chadron Formation of Oligocene age. Pabian used the term broadly to refer to any material found in such joints and included colors other than blue. The chalcedony is generally blue only in thick sections or in enhanced doublets. Pabian and Zarins (1994, p. 25, 26, figs. 48-53) used this material to define agates that formed in continentally deposited claystones, hence, continental sedimentary agates. |

Cross (1996, p. 63) has suggested that this is the same material that is found on Bishop Ranch, West Texas, and found in exposures of rocks that are of the same age in Mexico. These rocks have been mapped as Upper Cenozoic volcanics in Mexico by Sanchez-Mejorada (1960). Zarins (1977) suggested these agates came from the Buck Hills volcanics. |
450 | Bouquet Agate, West Texas, see Fahl, R. (1949, p. 174-176) for descriptions and illustrations. An adver-tizement by A. J. Burgard, Lapidary Journal, v. 3, no. 3, p. 177, suggested that Lelande Quick, then editor of Lapidary Journal, named this material at the April, 1949, Texas Gem and Mineral Show. QuickÆs description appears to have not been published at that time. ...no locality, no description, adv., Murphy's, Lapidary Journal, v. 15, no. 3, p. 310. See also Zeitner (1971, p. 4-22). |

471 | Brecciated Agate, descriptive term, used by Bauer (1896, p. 513) to describe shattered and recemented agate from Saxony, Germany. Zeitner (1964, p. 349) suggested the term brecciated be used for faulted agates in which the fragments were displaced and re-cemented out of their original position. See also ruin agate. We have observed many brecciated agates from the Ogalalla Formation of Miocene/Pliocene Age in Nebraska where included angular fragments of agate have originated from pedogenic (soil forming) processes rather than structural movement. Further, we have observed nodular agates with brecciation only happening to bands deep in the interior, suggesting the fracturing was not due to fault movement. |

About the Agate Lexicon
The Agate Lexicon and glossary of amorphous and cryptocrystalline silica gems have been designed to be used in conjunction with the Agate Bibliography, which was compiled to be used by researchers, hobbyists, historians, lapidaries and other individuals which have an interest in these stones. Numerous localities are listed here but this does not imply that the sites are available for collectors or collecting. Many of the sites are historic, depleted, are on private property or are protected by legal leases or claims and some are now on protected sites such as parks, nature preserves, or historic areas. Wherever possible, stratigraphic details are listed, but the user must always refer back to the original citations. Map information has been derived from 7.5' x 7.5' topographic maps issued by the U.S. Geological Survey (USGS) and latitude and longitude have been derived mostly from Geographic Names Information System of the USGS.
Authors should not cite the Agate Bibliography or Agate Lexicon as a source in their published or unpublished works but should cite only those publications listed therein.
Named varieties of agates, jaspers, etc., have created special problems for both scientific researchers and historians. We have recognized at least two different usages of names. Some names appear to have geologic / historic validity, as they were described along with the lithology / geography of a region. Some names were introduced simply as trade names to boost sales of gem dealers. In the former case, the name will be followed by appropriate literary citation as to who first used the name and in what context. In the latter case, an advertisement (abbreviated adv.) is the first published record or public notice. We have tried to find the earliest citation in either case and the user should keep in mind that older citations unknown to us may exist. Advertisements are not cited to generate business but to simply give a historic source; many of the firms appearing in the citations are indeed no longer in existence.
Cited materials are generally only from accessible sources such as professional journals, magazines, hobbyist journals, open file reports of government agencies, newspapers, etc. Bulletins issued by local clubs and societies are generally not cited with the exception of those special publications that were actually made for public distribution.
Wherever possible, imagery of one or more specimens of named agate varieties, structures, patterns, etc. are provided. Images have been provided by several sources and are not to be utilized in other pages without the consent of the image owner.
