Mineral Occurrence
4.11 DEPOSIT CONFIGURATION (E01)
Three optional fields are available to identify the shape, structural character and size of a mineral
occurrence. These fields are usually reserved for those occurrences which have received
sufficient exploration and development to have outlined a deposit.
4.11.1 SHAPE OF DEPOSIT (R06) (E06): An appropriate description of the
shape of the deposit is selected from the list below. The field is used only if
sufficient information is available to identify the shape. The shape should reflect
gross dimensions and discount minor irregularities. The coding geologist should
identify the shape of the mass of the ore minerals present and not just the host
setting. For example, mineralization within a vein or fault may be cylindrical or
bladed and not necessarily tabular.
Descriptions of the shape of a deposit are defined as follows:
Regular - The deposit is regular in shape and is approximately the
same dimension in all directions. Shapes range from spheroidal to
tetrahedral;
Tabular - The deposit has two long dimensions and one short
dimension. This would include veins, sills and dikes, etc.;
Cylindrical - The deposit has one long and two short dimensions
which are approximately equal. This would include pipes, ore
shoots, etc.;
Bladed - The deposit has one long, one medium and one short
dimension. Many deposits hosted by shear/fault zones or dikes will
belong to this category;
Irregular - The deposit has no discernible regularity of form.
4.11.2 SHAPE
MODIFIER (R04)
(E04): A structural
modifier is used to
support the data in the
deposit shape field. This
field cannot be used
unless deposit shape is
identified. The database
will accept up to two
modifiers.
