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).
What Is a Boat Transom? Your boat's transom is a critical part of the hull. The port and starboard sides of your boat are connected by the transom, located at the stern of your boat. Going forward, the two sides of your boat curve together and meet at the bow, forming the shape of the boat's hull. The transom on a small boat typically supports an outboard motor.
