4.3.1 Descriptive matrix

In descriptive matrices, short written descriptions are used. For each phase of a project, that is, site selection, construction, operation, and closure (if applicable), the various impacts associated with each activity are defined and short descriptions are provided. There is no scaling or quantification of these impacts. Table 4.1 presents a structure of the descriptive matrix for a quarry.
