MINE PLANNING BASICS FRIDAY - STRATIFIED DEPOSITS!!

Stratification, the layering that occurs in most sedimentary rocks and in those igneous rocks formed at the Earth’s surface, as from lava flows and volcanic fragmental deposits. The layers range from several millimetres to many metres in thickness and vary greatly in shape. Strata may range from thin sheets that cover many square kilometres to thick lens-like bodies that extend only a few metres laterally - Encyclopaedia Britannica.
