separation of coal and packstone

Introduction to Carbonate Facies, Depositional Environments,

Packstone: Grain-supported muddy carbonate rock (Dunham, 1962). Lucia (1999) divided packstones into mud-dominated (pore spaces totally filled with mud) and grain-dominated (some intergrain pore space is free of mud) packstones. This division is important in understanding reservoir quality because mud plugs interparticle pore spaces. Packstones indicate a range of

Separation of coal macerals (Journal Article)

Abstract The conditions necessary for efficient, small-scale separation of coal macerals are investigated. The method developed takes advantage of known density differences of the various macerals, but unlike most separations, an isopycnic density gradient centrifugation (DGC) technique is used to isolate pure macerals.
