Pencil - Wikipedia
A pencil / ˈ p ɛ n s ə l / is a writing or drawing implement with a solid pigment core encased in a sleeve, barrel, or shaft that prevents breaking the core or marking a user's hand.. Pencils create marks by physical abrasion, leaving a trail of solid core material that adheres to a sheet of paper or other surface. They are distinct from pens, which dispense liquid or gel ink onto the,Sedimentary exhalative deposits - Wikipedia,Sedimentary exhalative deposits (SedEx or SEDEX deposits) are zinc-lead deposits originally interpreted to have been formed by discharge of metal-bearing basinal fluids onto the seafloor resulting in the precipitation of mainly stratiform ore, often with thin laminations of sulphide minerals. SEDEX deposits are hosted largely by clastic rocks deposited in intracontinental riftsGold Deposits and Their Geological Classification,Robert, F., Poulsen, K.H., and Dubé, B.

White cast iron White cast iron has a light appearance. White CI, so called due to its very white structure, can be formed only during solidification. It has carbon only as a "carbide," which makes white cast irons extremely hard and resistant to abrasion. However, white cast iron is even more brittle than grey cast iron 3.2010 Standard Occupational Classification System,Jun 20, 2018· Plan, direct, or coordinate the operations of public or private sector organizations.
