Ore minerals in IOCG deposits are typically copper-iron sulfide chalcopyrite and gangue pyrite, forming 10–15% of the rock mass. Supergene profiles can be developed above weathered examples of IOCG deposits, as exemplified by the Sossego deposit, Para State, Brazil , where typical oxidised copper minerals are present, e.g.; malachite ...
Mesh is a measurement of particle size often used in determining the particle-size distribution of a granular material. For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh.
You can still use a blank as a Q, W, X or Y, but not as DZ or DZS. Using a D tile and a Z tile to make DZ or putting together D, Z and S or D and ZS to make DZS is not allowed, meaning words with these two letters are simply not playable. Using a blank (as Y) in front of G, L, N or T to make GY, LY, NY or TY is also not allowed. [citation needed]
