Proposed Amendments to the Science TEKS At the January/February 2017 State Board of Education (SBOE) meeting, the SBOE approved for first reading and filing authorization proposed amendments to the science Texas Essential Knowledge and Skills (TEKS) for Kindergarten – Grade 8 and certain high school courses. The proposed amendments would streamline the science TEKS with a recommended implementation date of the 2017-2018 school year. The SBOE is scheduled to consider the proposed amendments for second reading and final adoption at its April 2017 meeting. The official public comment period for the proposed amendments to streamline the science TEKS is now open. Please note that the SBOE has specifically requested feedback regarding the amount of time to provide instruction in the proposed student expectations. Specific feedback related to the time needed to teach individual concepts would be helpful.

For Your Shopping Pleasure Over Spring Break1 We are back from our 25-day shopping trip at the International Tucson Gem, Mineral & Fossil Show where we restocked for our 2017 inventory needs by hunting down the industry leaders for new and exciting treasures. It took 3 trucks to bring back most of what we accumulated, and we can't wait to share it all with you! Many items are one of a kind creation from Mother Nature, so be sure to come early for the best pieces available. There will be special pricing on some of our most popular items like Arkansas Quartz clusters, Rose Quartz and Amethyst tea lights, loose moldavite, and select vendors. Below we have featured some of the new products we found. We'll see you Saturday morning at 10:00!! This year Kyanite seemed to be everywhere. We brought back Kyanite blades, barrels of beautiful blue Kyanite in pure white quartz, a new tri colored Kyanite and an eye catching new aqua blue color Kyanite called Paraiba Kyanite. We were able to buy another batch of natural Quartz Lazer wands from the same vendor as last year. We scored a find of clear double-terminated Tibetan crystals that were hand-picked from a 1980 private collection. Shungite is still being incorporated into new styles and configurations for everyone to add in their lives. Lastly, we are excited to have found a new vendor who will be working with us to create new Himalayan Salt lamps, tools and decor for your home, office and altars.

Experiments especially by Fourier transformed infrared spectroscopy, were applied to a wide range of samples with controlled origin. The methods were optimised and resulted in premises to apply the techniques to analysis of the archaeological material.

The resin-bearing strata are intercalated within the lower and medium part of the lower Kliwa Amber is a fossil resin originating from different types sandstone (0.20-1.40 m). They consist of siliceous clay of Conifers and certain flowering trees, especially in hot (0.20-1.40 m) always containing thin intercalations of climates. From the mineralogical point of view amber bituminous shales (2-5 cm) and of preanthracite coal could be considered a mineraloid.

  • Sugilite in Manganese Silicate Rocks from the Hoskins Mine and Woods Mine, New South Wales, Australia
    Sugilite in manganese silicate rocks from the Hoskins mine and Woods mine, New South Wales, Australia Y. KAWACHI Geology Department, University of Otago, P.O.Box 56, Dunedin, New Zealand P. M. ASHLEY Department of Geology and Geophysics, University of New England, Armidale, NSW 2351, Australia D. VINCE 1A Ramsay Street, Essendon, Victoria 3040, Australia AND M. GOODWIN P.O.Bo• 314, Lightning Ridge, NSW 2834, Australia Abstract Sugilite relatively rich in manganese has been found at two new localities, the Hoskins and Woods mines in New South Wales, Australia. The occurrences are in manganese-rich silicate rocks of middle to upper greenschist facies (Hoskins mine) and hornblende hornfels facies (Woods mine). Coexisting minerals are members of the namansilite-aegirine and pectolite-serandite series, Mn-rich alkali amphiboles, alkali feldspar, braunite, rhodonite, tephroite, albite, microcline, norrishite, witherite, manganoan calcite, quartz, and several unidentified minerals. Woods mine sugilite is colour-zoned with pale mauve cores and colourless rims, whereas Hoskins mine sugilite is only weakly colour-zoned and pink to mauve. Within single samples, the chemical compositions of sugilite from both localities show wide ranges in A1 contents and less variable ranges of Fe and Mn, similar to trends in sugilite from other localities. The refractive indices and cell dimensions tend to show systematic increases progressing from Al-rich to Fe- Mn-rich. The formation of the sugilite is controlled by the high alkali (especially Li) and manganese contents of the country rock, reflected in the occurrences of coexisting high alkali- and manganese- bearing minerals, and by high fo2 conditions.

Agpaitic nepheline syenites have complex, Na-Ca-Zr-Ti minerals as the main hosts for zirconium and titanium, rather than zircon and titanite, which are characteristic for miaskitic rocks. The transition from a miaskitic to an agpaitic crystallization regime in silica-undersaturated magma has traditionally been related to increasing peralkalinity of the magma, but halogen and water contents are also important parameters. The Larvik Plutonic Complex (LPC) in the Permian Oslo Rift, Norway consists of intrusions of hypersolvus monzonite (larvikite), nepheline monzonite (lardalite) and nepheline syenite. Pegmatites ranging in composition from miaskitic syenite with or without nepheline to mildly agpaitic nepheline syenite are the latest products of magmatic differentiation in the complex. The pegmatites can be grouped in (at least) four distinct suites from their magmatic Ti and Zr silicate mineral assemblages.

Nielsen 2 1 Vernadsky Institute of Geochemistry and Analytical Chemistry, Russian Academy of Sciences, 119991 Moscow, Russia 2 Geological Survey of Denmark and Greenland, 1350 Copenhagen, Denmark; [email protected] * Correspondence: [email protected] Received: 23 September 2020; Accepted: 16 November 2020; Published: 20 November 2020 Abstract: Lovozero complex, the world’s largest layered peralkaline intrusive complex hosts gigantic deposits of Zr-, Hf-, Nb-, LREE-, and HREE-rich Eudialyte Group of Mineral (EGM). The petrographic relations of EGM change with time and advancing crystallization up from Phase II (differentiated complex) to Phase III (eudialyte complex). EGM is anhedral interstitial in all of Phase II which indicates that EGM nucleated late relative to the main rock-forming and liquidus minerals of Phase II. Saturation in remaining bulk melt with components needed for nucleation of EGM was reached after the crystallization about 85 vol. % of the intrusion. Early euhedral and idiomorphic EGM of Phase III crystalized in a large convective volume of melt together with other liquidus minerals and was affected by layering processes and formation of EGM ore. Consequently, a prerequisite for the formation of the ore deposit is saturation of the alkaline bulk magma with EGM. It follows that the potential for EGM ores in Lovozero is restricted to the parts of the complex that hosts cumulus EGM. Phase II with only anhedral and interstitial EGM is not promising for this type of ore.
