Mineral Occurrence<br />
Industrial Mineral 21<br />
Industrial minerals, including stone <strong>and</strong> rocks, may be defined as those naturally occurring materials used to<br />
build structures or supply products that are useful to an industrialized society. Since industrial minerals<br />
exclude the ores <strong>of</strong> metals, they have been called the "nonmetallics". Gems <strong>and</strong> art objects are valuable for<br />
their intrinsic properties, but because they are not used in the sense <strong>of</strong> structures or products, they are not<br />
included. Industrial-grade diamonds <strong>and</strong> semiprecious minerals, however, are useful to industry because <strong>of</strong><br />
their hardness <strong>and</strong> are included under abrasives. Listed below are commodities which are considered by<br />
MINFILE to be Industrial Minerals.<br />

Deposit types are based on the British Columbia Mineral Deposit Pr<strong>of</strong>iles (http://www.empr.gov.bc.ca/<br />
mining/Geoscience/MineralDepositPr<strong>of</strong>iles/Pages/default.aspx) <strong>of</strong> the BC Geological Survey.<br />
The Deposit type is an attempt to define a deposit based on its characteristics <strong>and</strong> includes/implies an<br />
explanation <strong>of</strong> these characteristics in terms <strong>of</strong> geological processes. The database will accept up to<br />
four Deposit types for any given occurrence. See Appendix XIV for a list <strong>of</strong> all valid Deposit types.<br />
This field is optional since there is <strong>of</strong>ten not enough information to define many occurrences as a<br />
specific deposit type. The coding <strong>of</strong> deposit type is ranked, using the most important type as the first<br />
ranked. The ranked order will be reflected in the printout.<br />
A thorough deposit description should be incorporated in the Capsule Geology <strong>and</strong> should indicate the<br />
geological evidence for any <strong>and</strong> all interpretations.<br />
4.7 AGE OF MINERALIZATION (R24) (E24)<br />
The geologic age <strong>of</strong> the mineralization is indicated with an appropriate era, period or epoch. A complete<br />
listing <strong>of</strong> acceptable codes is provided in Appendix V, Stratigraphic Age Codes <strong>and</strong> is available for<br />
online coding with the list box. This is an optional field <strong>and</strong> should be used only if substantial evidence<br />
supports the data. This evidence must be stated <strong>and</strong> referenced in the Structural <strong>and</strong> Age Comment<br />
field <strong>and</strong> in the Capsule Geology. If the age <strong>of</strong> mineralization is known then the Isotopic age <strong>and</strong><br />
Material Dated fields should also be filled in. When coding via the MINFILE/www online coding card<br />
