Agate Structures, Part 2
Agate Structures, Part 2: Dendrites, Plume, and Moss Agate There aren't any hard and fast rules that define and differentiate them, and in common practice appearance more than content defines one as “plume” and another as “moss” or “dendrite”. And, as some types of mosses, plumes and dendrites overlap or grade into one another along a continuum, a lot of latitude in labeling has to be expected. There are real differences among some of them however so I am going to sort them out into several groups based on how they appear and how they were formed, as best I can tell. Scrap Moss, and other Nondescript Moss Let me begin with a 'moss' that we know something about already – mineral exclusion bands. Many patterns we see in agate that appear on cut surfaces to be filaments or plumes are actually sheet like, albeit perhaps discontinuous and localized in extent. This San Carlos agate, which would probably be considered a 'moss agate' contains a wild melange structures that appear to be, in large part, mineral exclusion bands. They would consist then of finely distributed non-silica material contained in the agate seam that was simply swept up into layers by countervaling crystallization fronts moving outward from an array of various nucleation surfaces. San Carlos Agate, Mexico Speaking of Agates and God, and Man - Agate Structures, Part 2 © 2015 Bill Kitchens That out of the way, let's begin our look at 'moss agate' with what seems the simplest of the moss agate structures, and one unrelated to the other structures known as 'moss'. -
AFMS Merit Badges
AMERICAN FEDERATION OF MINERALOGICAL SOCIETIES Future Rockhounds of America Badge Program Fourth Edition Jim Brace-Thompson AFMS Juniors Program Chair [email protected] (805) 659-3577 This packet is available on-line on the AFMS website: www.amfed.org © 2004, 2008, 2010, 2012, 2016 Jim Brace-Thompson & the American Federation of Mineralogical Societies AMERICAN FEDERATION OF MINERALOGICAL SOCIETIES Future Rockhounds of America Badge Program MISSION STATEMENT Future Rockhounds of America is a nationwide nonprofit program within the American Federation of Mineralogical Societies that develops and delivers quality youth activities in the earth sciences and lapidary arts in a fun, family environment. Our underlying goals are to foster science literacy and arts education through structured activities that are engaging and challenging and by which kids—and the adults who mentor them—learn while having fun. INTRODUCTION . Philosophy behind the FRA Badge Program & Suggestions on Using It I’ve developed this manual so as to enable the American Federation of Mineralogical Societies to sponsor a youth program via Future Rockhounds of America, a program that rewards kids on an on-going basis as a means of encouraging and cultivating their interest in the earth sciences and lapidary arts. Through this, each of our individual clubs and societies will uphold our chartered goals as nonprofit, educational organizations by actively seeking to foster and develop science literacy and arts education amongst our youngest members. My guiding philosophy has three underpinnings. They come from both my own values as a person invested in the positive development of young people and from a wealth of academic research indicating that if one wants to design and deliver programs that effectively promote positive development among young people, three steps are crucial to enact. -
Section IX the STATE PAGES
Section IX THE STATE PAGES THE FOLLOWING section presents information on all the states of the United States and the District of Columbia; the commonwealths of Puerto Rico and the Northern Mariana Islands; the territories of American Samoa, Guam and the Virgin Islands; and the United Na tions trusteeships of the Federated States of Micronesia, the Marshall Islands and the Republic of Belau.* Included are listings of various executive officials, the justices of the supreme courts and officers of the legislatures. Lists of all officials are as of late 1981 or early 1982. Comprehensive listings of state legislators and other state officials appear in other publications of The Council of State Governments. Concluding each state listing are population figures and other statistics provided by the U.S. Bureau of the Census, based on the 1980 enumerafion. Preceding the state pages are three tables. The first lists the official names of states, the state capitols with zip codes and the telephone numbers of state central switchboards. The second table presents historical data on all the states, commonwealths and territories. The third presents a compilation of selected state statistics from the state pages. *The Northern Mariana Islands, the Federated States of Micronesia, the Marshall Islands and the Republic of Belau (formerly Palau) have been administered by the United Slates since July 18, 1947, as part of the Trust Territory of the Pacific Islands (TTPl), a trusteeship of the United Nations. The Northern Mariana Islands separated themselves from TTPI in March 1976 and now operate under a constitutional govern ment instituted January 9, 1978. -

Agate Structures, Part 1 © 2015 Bill Kitchens
Agate Structures I: Formation and Classification of Common Agate Structures. Putting a Name on an Agate So, now we have some basic classifications of agates – those formed in volcanic host rocks and those formed in sedimentary host rocks. Agates that form in pockets, massive seam agates, and vein agates that are planar in shape. Then there are the fossil and mineral replacement agates that take the shape of the structure replaced. To those basics, we can add whole arrays of identifiers; some descriptive of patterns like fortification and moss or plume. Other identifiers are based on location like 'Lake Superior', 'Death Valley', 'Bloody Basin'; and some are proprietary trademarked names like 'Prudent Man' and 'Royal Aztec Lace'. Some of the more common terms describing the Brazilian Agate appearance of agate are wall banded, water-level, onyx, shadow, lace, eye, moss, plume, dendritic, tube, drape, sagenite, pseudomorph, geode, flame, stalactite, floating, brecciated, and ruin. Even stringing several of these classifiers together, as in “Laguna Lace”, or “Lake Superior Sagenite” can't adequately describe the simplest agate but it will put it in the ball park. Coming up is a section describing and attempting to explain some of the structures we see in agate. Realizing that one photo is worth a thousand words, we'll look at numerous of examples of these structures as we go along. Speaking of Agates and God, and Man – Agate Structures, Part 1 © 2015 Bill Kitchens Color and Color Banding Please recall from a few pages back (if you take these pdfs in series), that I spoke of crystallization and banding as inextricably interconnected, which they are – but also complexly interconnected.
