A rare earth mineral is a mineral that contains one or more rare earth elements as major metal constituents.Rare earth minerals are usually found in association with alkaline to peralkaline igneous complexes, in pegmatites associated with alkaline magmas and in or associated with carbonatite intrusives.Perovskite mineral phases are common hosts to rare earth elements within the alkaline complexes.he following includes the relatively common hydrothermal rare earth minerals and minerals that often contain significant rare earth substitution: 1  aeschynite. 2  allanite. 3  apatite. 4  bastnaesite. 5  bastnÃ¤site. 6  britholite. 7  brockite. 8  cerite. 9  fluocerite. 10  fluorite. 11  gadolinite. 12  monazite. 13  parisite. 14  stillwellite. 15  synchysite. 16  titanite. 17  wakefieldite. 18  xenotime.  zircon
A boat is a watercraft of a large range of sizes designed to float, plane, work or travel on water. Small boats are typically found on inland waterways (e.g., rivers and lakes) or in protected coastal areas. However, boats such as the whaleboat were designed for operation from a ship in an offshore environment. In naval terms, a boat is a vessel small enough to be carried aboard another vessel (a ship).
The maritime history of the Pacific Northwest is preserved and documented in a unique museum in Seattle called the Center for Wooden Boats. Boat enthusiasts and other visitors can not only view the wooden boats but touch the boats, row, paddle or sail in the collection of classic wooden boats at the museum. Architect Dick Wagner designed the Center for Wooden Boats at Waterway #4 at South Lake Union and the first campus opened in 1981. The events and exhibits at the first museum gained great popularity and in 2008 a new campus was rented by the Center at the Cama Beach State Park, north of Seattle.
