Mineral measures

Sample reference

sample_reference

Sample reference is a unique identifier assigned first by the compiler and then by the IsoArcH database to each collected sample. In each dataset, these numbers will span from 1 to n, with n representing the maximum number of samples compiled. Once in the IsoArcH database, this identifier will include the dataset number as a prefix. GRIST may automatically populate this field. Example: 1

Tooth fraction

tooth_fraction

Legacy names

fraction of tooth sample

Tooth fraction refers to the particular portion of the tooth that has been sampled.

Allowed Values:

  • dentine
  • enamel
  • pulp

Result type

result_type

Result type is a field that enables specification of the type of measured value being reported. When multiple values, such as a range, are applicable to a specific sample, this field should be completed multiple times, each on a separate line.
