"Gemstorm begins with a Mineralogical Museum tour" Uly4's photos around Belo Horizonte, Brazil A TripAdvisor™ TripWow slideshow of a travel blog to Belo Horizonte, Brazil by TravelPod blogger Uly4 titled "Gemstorm begins with a Mineralogical Museum tour.". TravelPod is a company of TripAdvisor™. Uly4's travel blog entry: "Day 1 Lagoa Santa / Belo Horizonte, Minas Gerais, Brazil August 21, 2009 10:00 am ( local time ) Day 1 -- August 21-- Friday : Arrival in Belo Horizonte. Arriving Belo Horizonte, you will be met at the airport "Confins". Start with a tour of the city of Belo Horizonte and a visit to the Mineralogical Museum of Belo Horizonte (Professor Djalma Guimarães Museum of Mineralogy). Enroute visit to interesting geological outcrops on the way driving to Ouro Preto. Today was one of those lucky days... Everything worked like a chime: flight on time at 8:35am, picking up the Zealey couple at the hotel at 8:30am; arriving at the Mineralogy Museum in Belo Horizonte at 10:30am; lunch by the pool at the restaurant "Chão de Minas" with the best traditional local food in a quiet an very pleasant location where we also visited a "cachaça" distilery at noon time (old equipment kept alive), this is Geotourism; arrive at the "Capão Mine", the only commercial operated imperial topaz mine in the world at 2:00pm, sharply! CONTINUE ON NEXT ENTRY... Overnight in Ouro Preto, Minas Gerais, Brazil, at the Bed & Breakfast Sinhá Olimpia. Belo Horizonte Since the planned uprising of the Inconfidentes in 1789, the residents of the state had dreamed of a ...

Optical mineralogy calcite variable relief Calcite in plane polarized and cross polarized light, showing variable relief against quartz (plane polarized light) - note variable darkness of grain boundary in center of field of view. In cross-polarized light, calcite shows high interference colors and twins. Quartz shows typical black-white colors in cross-polars.

Part 1: Gale Mineralogy & Stratigraphy Gale Crater is one of the candidate landing sites for the Mars Science Laboratory. In this video, Dawn Sumner gives a tour of places in the lower mound of Gale where the MSL rover could investigate the origins and stratigraphic relationships of clay and sulfate minerals. She describes stratigraphic relationships where CRISM spectra suggest different minerals are present as reported by Miliken et al., (2010). Watch in HD, full screen to see the cursor pointing out details. The imagery used includes a CTX mosaic (provided by Miliken) and HiRISE images. Both are draped over MOLA, HRSC, and HiRISE DEMs. The images and DEMs are not perfectly correlated in this data set, leading some edge effects. The video shows real-time manipulation of the data in the program Crusta running on Vrui, written by Tony Bernardin and Oliver Kreylos, respectively, as part of the Keck Center for Active Visualization in Earth Sciences, UCDavis. See The video was captured using ScreenFlow (commercial software). Simultaneously running Crusta and ScreenFlow taxes the memory of my laptop (a MacBook Pro with only 4 GB of RAM), so Crusta responds much more slowly in the video than it does when I'm not also using ScreenFlow.
Optical Mineralogy birds-eye extinction muscovite biotite Muscovite and biotite in cross-polarized light, showing distinctive birds-eye (mottled) extinction. Brief images in plane-polarized light show distinguish muscovite (clear) from biotite (brown).

Optical Mineralogy chloritoid rutile inclusions garnet Chloritoid (large blue and green pleochroic grains) and rutile inclusions inside a large garnet porphyroblast, in plane polarized and cross-polarized light. The rutile shows up best in cross-polarized light as bright needles.
Dino-Lite by Applications - Mineralogical Dino-Lite digital microscopes are a perfect solution for mineralogy and geology. Since Dino-Lites are lightweight and portable, they are ideal for professionals and students traveling to excavations sites or to multiple facilities. Dino-Lites are helpful for identifying minerals, fossils, cataloging, lecture presentations, and publishing.

Earth Science: Mineralogy - K4517DVD Excerpt from Mineralogy: Conserving Our Precious Minerals from the Show Me Science series from TMW Media to purchase this title on DVD, go to Summary: Throughout history, minerals have played an important role in the story of human progress. Advancing through the ages of electricity, the Industrial Revolution and the Microelectronics age, modern civilization has been built upon the use of earths mineral resources. This program surveys the sources and uses of some of the minerals which have become most important to us and looks at efforts to conserve and find suitable substitutes for these indispensable, non-renewable, natural resources. Includes suggestions for careers in this field of study. Terms Covered In This Edition Include: Catalytic Converter, Conductor, Copper, Crust, Fiber-Optic Cables, Galvanizer, Geology, Gold, Iron, Mineral Ore, Platinum, Rust, Silicon, Silver Relevant Curriculum Areas: Conservation, Earth Science, General Science, Geology, Mineralogy, Technology 12 min.
