    MINUTES OF THE JANUARY MEETING

    The January regular meeting of the Nova Scotia Mineral & Gem Society was held on Saturday, January 27, 2001 at the Nova Scotia Museum of Natural History. The meeting was called to order at 7:42pm with President Ken McKenzie sitting as chair and 13 members and 2 guests present.

    President McKenzie welcomed everyone to the first meeting of the new year and called attention to mineral theme for the month - white minerals. Examples brought in included ulexite (aka TV stone), thompsonite and analcite (analcime). Entertainment following the business meeting was to be the video 'Walking with the Dinosaurs' (a BBC production).

    Terry Collett moved to approve the minutes of the December meeting as they appeared in the Rockhound's Bark with the correction in the spelling of Martin Eirisch's name. Clarence Huard seconded the motion - carried.

    There was a short discussion on next month's auction of specimens donated by Doug Wilson's company MinCity. There will be a minimum bid of Doug's cost and any additional monies taken in will go to the Society's coffers. Other sources for publicising the auction to attract non-members were suggested such as the 'Coffee News', 'Community Bulletin Board' and 'What's Going On'. Alternate suggestions should be passed on to Ken McKenzie or Brenda Roscoe to be utilised.

    Terry Collett gave a brief synopsis of upcoming field trips for the year. His suggestions included: Boylston & Moosepoint for rock crystal and specular hematite, East Kemptville tin mine for serious collectors of microminerals, Blackrock to Harbourville for zeolites, and Amethyst Cove by boat.

    The Amethyst Cove trip would cost about $30.00 per person assuming that 20 people participate. Transportation to the site would be by a large fishing boat and from there a Zodiac would taxi people up and down the shore. Terry stressed the importance of field trip safety and passed out a handout for people to review. All individuals need to be responsible for their own actions and safety.

    Our liability insurance through the GMFC was discussed. Gordon Stewart discovered last year that we are not officially incorporated as a Society. If we were then individuals should not be able to be held liable as any actions would be against the Mineral & Gem Society. Incorporation would cost an initial $35.00 and an annual fee of $25.00. It would require a five member board of directors (which don't necessarily have to be society members) which would meet once a year to make sure the society is fulfilling it's mandate. Gordon Stewart suggested that before we make our application we seek legal advise about whether incorporating would also protect the board members from legal action.

    New Business:

    The Nova Scotia Mineral & Gem Society now has an official Web Site. It is still a work in progress but shaping up really well. To view log on to http://accesswave.ca/~nsmgs/.

    Brenda Roscoe reported on the deadlines for Museumnews. Unfortunately they are very far in advance of the publication date. The deadline for all our upcoming events has passed and we do not have anything planned far enough ahead for the next one as yet. Imelda suggested that we advertise our new Web Page address in Museumnews and various other media sources.

    Unfortunately the museum still has no other meeting night available. Only one club meets more than once a month and those days are Monday and Sunday. If they were at all interested in trading a night it would probably be the Sunday. Brenda Boutilier assured us if another night does become available we will have first refusal.

    Correspondence included several newsletters and information on the Manitoba Show from the GMFC. These items were tabled for members to peruse. The GMFC also requested some sort of display of Nova Scotian minerals to be sent to the national show in Manitoba. As none of the members were interested in sending their specimens to Manitoba without accompanying them a photo display or video was discussed. The deadline to ship the display is the end of May. Ken McKenzie received an E-mail from a gentleman in Vancouver who will be in our region in the near future and was interested in accompanying us on any field trips we might have planned. Ken will respond. Also a letter was received from someone looking for information on radioactive rocks around the Yarmouth area. Brenda Roscoe will respond to the request.

    Andrew Brock requested that anyone who currently has any of the Society's books out return them to the February meeting so he can consolidate the library. Once this task is done a complete list of our reference material will be published.

    Terry Collett moved to adjourn the meeting at 8:42pm. The motion was seconded by Imelda O'Toole.

    Respectfully Submitted

    UPCOMING PROGRAMS

    February - Mineral Auction

    Doug Wilson, owner of Mineral City, is bringing in lots of specimens to be auctioned off. There will be a minimum bid on all items to cover costs and proceeds above the minimum bids will donated to the club. This is a great fundraising event, and an excellent opportunity to get some great collection pieces. The event is open to the public, so spread the word, bring your friends, and don't forget to bring along some money!

    March - Pseudomorphs

    As the meeting falls the day before April Fool's Day, it would only be appropriate to discuss pseudomorphs, nature's way of trying to fool us. Ronnie Van Dommelen will do a short talk on how the various types of pseudomorphs occur. Examples from Nova Scotia and around the world will be on display. Pseudomorphs will also be the minerals of the month.

    April - Fluorescent Minerals

    April will be devoted to fluorescent minerals. Andrew Brock will do a talk, and everyone will get a chance to use the club's UV lights. Specimens from Nova Scotia and other parts of the world will be on hand for viewing. Fluorescents will be the minerals of the month as well, so bring on your specimens. If you are not sure your specimens fluoresce, have them checked out - especially calcites.

    May - Lapidary Night

    A lapidary night is planned for the May meeting. Details still have to be worked out.

    LIBRARY BOOKS

    Club librarian Andrew Brock has nearly completed an ambitious project to catalogue all the club books. This spring the complete list will be added to the Bark and as a permanent list on the club website. However, to ensure a complete list, Andrew has requested that members bring to the February meeting any books they may have borrowed from the club library. If this is not possible, please contact Andrew (phone/email) with the details of the books that you have.

    MEMBERSHIP RENEWAL

    This is the final notice for membership renewal. For those who paid the old fee ($15) early, we ask that you send the additional amount to Imelda. Single membership fees are $20.00 per year, plus an extra $2 for any additional family member who wishes to join the Society. The increase in single membership fees will help to cover the new cost of renting the museum auditorium. The extra family member charge will cover our insurance costs. Along with your payment, you should print and fill out the following information sheet. If you do not have a printer, a copy can be sent out to you. Sorry for any inconvenience.

    TUCSON 2001

    The annual mineral, fossil, and gem show in Tucson, Arizona is the world's largest. The whole city is turned into a shop with nearly every hotel and public venue participating. As well, many new mineral finds are revealed at the show. Probably the best show report I have seen can be found at Bob's Rock Shop. To see some additional specimens that were for sale from the show, check out The Virtual Show.

    NEW DINOSAUR DISCOVERED

    A new Late Cretaceous (65-70 million years ago) dinosaur has been discovered in Madagascar. The discoverers gave it the name Masiakasaurus knopfleri, with the species name coming from all things Mark Knopfler, former lead singer of the rock group Dire Straits (the discoverers listened to a lot of Dire Straits music while digging). Remains from about six individuals have been found, including jaws and about 40 percent of the rest of the skeleton. An artist's drawing of what the dinosaur might have looked like is shown at right. Below right is a photo of the digging site.

    The dinosaur was a 1.8 metre (6 ft) long meat-eating creature. It weighed about 35 kg (80 lbs) or about the size of a German shepherd dog. The most interesting feature of this new creature are its unique teeth and jaws which are unlike any other dinosaur's. In fact, it is so bizarre that when it was first found, the discovers were unsure it was even dinosaur. However further research revealed that it was indeed a dinosaur.

    The first tooth of the lower jaw projects outward, almost horizontally, rather than up. Teeth further into the mouth point at increasingly vertical angles. Some modern day shrews have a similar dental arrangement and typically the front teeth are used for grasping and piercing, while the back teeth are for tearing and slicing.

    Huge Crystal Cave Found

    The Discovery Channel has reported that gigantic crystals of selenite, reaching over 7m (20ft) in length have been found in a mine near Naica, in Chihuahua, Mexico. This mine system is also the sight of the famous Cave of Swords, however the new crystals are ever larger. Two caves were discovered, the larger being described as the size of a cathedral. The caves are extremely hot, reaching 65C (150F). The mining company plans to slowly cool the caves and open them for public viewing. Although the caves are currently being protected, some collectors have broken locks to gain access to the caves. One man was even killed when the huge crystal he was trying to remove crushed him. One mistake in the article is that they call them the largest natural crystals on Earth. While this may by true for selenite, beryl crystals have been found to 18m in length. For more info and a photo, click here.

    Thanks to Ken McKenzie for bringing attention to this article.

    COLLECTING ROCKS

    I think that there shall never be
    An ignoramus just like me
    Who roams the hills throughout the day
    To pick up rocks that do not pay
    For there's one thing that I'm told
    I take the rocks and leave the gold
    Over deserts wild or mountains blue
    I search for rocks of varied hue
    A hundred pounds or more I pack
    With blistered feet and aching back
    And after this is said and done
    I cannot name a single one
    I pick up rocks where ever I go
    The reason why, I do not know
    For rocks are found by fools like me
    Where God intended them to be

    MINERAL CDS

    The Photo-Atlas of Minerals

    In The Photo-Atlas of Minerals, data is available for nearly all approved minerals (about 4000). More importantly, photographs are included for about 800 of those species. When you consider well crystallized minerals that are common enough for the average collector to own, 800 species is nearly all you will need. However, these 800 species are represented by more than 6,500 pictures. Many photographs are included for a single species to show the variation in colour and crystal habit from various localities. For more info, click here.

    The Photographic Guide to Mineral Species

    In contrast to the Photo-Atlas, The Photographic Guide to Mineral Species is interested in the rare minerals. Most books tend to show the same minerals over and over, and it is often extremely difficult to find a picture of a rare mineral. This CD contains over 5000 photographs of more than 3000 species, enough to keep even the collector of rare minerals busy for quite some time. For more info, click here.

    Atlas Der Krystallformen

    In the days before microprobes and x-ray diffraction, one of the best ways to learn about a mineral was by studying the crystal forms. In the early part of this century Victor Goldschmidt reached the pinnacle of classical crystallography when the Atlas was released. It contains more than 23000 crystal drawings. It is still used as a reference book and many drawing found in the Mineralogical record come from the Atlas. This important work has been preserved by scanning the entire work and distributing it on CD. While it is in German, it is relatively easy to translate the mineral names and the drawings are universal. For more info, click here.

    HOW DO YOU PRONOUNCE THAT?

    "Widgiemoolthalite" the person says again, and you don't know whether to nod and smile or say "Gesundheit". Ever run into those mineral names that keep you up at night? Like uchucchacuaite, xitieshanite, or zvyagintsevite. Even goethite (which sounds like gertite) can give problems (I say this one wrong too; bad habit). Well did you know there is a place you can go to for help? The Mineralogy Database has proper pronunciations for all the minerals along with all the other important data you might need. If your computer is equipped with a sound card and speakers, check it out. It's lot of fun and may bring you a night of pleasant dreams.

    LINKS

    I forgot to add new links to the bark last month, so here are some new links one month late. This month features a selection of European mineral websites.
