User and Contributor Manual

Editing a Locality

If you would like to add more information to a locality page, use the following instructions to add and/or edit information regarding the locality. Note: all edits will go through an approval stage before being updated – don't expect the changes to show immediately.

Editing a Locality

Navigate to the locality page you wish to edit. In the blue header bar of the locality page, select “Edit,” then “Edit Locality.” This will direct you to a form page for entering information.

This is the same form page covered in Adding a New Locality, but has already had some data filled in by other users. Please reference that article for details about each of the data boxes.

Adding New Minerals and Rocks to a Locality

Note that when adding new minerals/rocks to a locality, you must provide a reference – literature references are preferred, but personal references are also accepted. This provides an important quality check for the database, and also allows anyone interested in that locality to find any published works about that locality. Be sure that your references are formatted correctly: see References.

Adding New Minerals/Rocks

To begin adding new minerals and/or rocks to a locality, select "Edit" in the locality header, then "Add Minerals." This will navigate you to a form page for adding minerals and rocks.

To add a mineral or rock that is not previously described from this area, type the name into the Minerals to add/update box.

Multiple minerals or rocks from one reference can be added at the same time by entering them individually on their own line – all entries added at the same time will be given the same reference, so entries from more than one source must be added separately with the corresponding reference. If the reference also mentions minerals or rocks previously added to the locality, you can check the box in front of the listing in the left hand column to add the reference to that listing.

If you enter a synonym for a mineral, the approved name for the mineral will be shown. Varietal names will be shown in the list as the varietal name – for example, if you list quartz, rose quartz, amethyst, and smoky quartz, all four minerals will be added to the mineral list as separate entries.

If you add a mineral that is already listed for the locality, the program assumes you wish to add another reference for that mineral.

If you receive an error stating that one or more minerals were not recognized, check for spelling errors and retry.

Literature Reference

Enter the respective reference in the format described.

Use the check box below to indicate whether the reference added is a new reference (default - unchecked) or an update to a previous reference that will replace the previous reference.

Personal Reference

Mindat allows references other than citations from literature – this enables the database to record occurrences that are not yet published and document occurrences found by amateur collectors. To add a personal reference, enter the details of the reference, then select the method used to determine how the mineral/rock was identified. You can hold control and click to add multiple methods. You can also distinguish whether the information came from a specimen personally collected, a dealer, or other.

Caution: the use of “visually identified” will receive heavy scrutiny during manager approval. This option is not intended to circumvent the research or use of any existing published data. If the material in question is crystallized with distinct crystals or other visually distinctive properties are present, this information should be included to support the visual identification.

Once you are finished entering data and are ready to submit the form to add your list of minerals/rocks to the location, select “Add/Update these minerals.” If you have not provided references, these minerals will not be submitted to review for approval.

Adding Details about Minerals at a Locality

You can add further detail to individual minerals reported at a locality by selecting their name in the left hand column. This will navigate you to the Edit Mineral Occurrence Information page. The data entered here will appear on the locentry page (a page that page that includes data about the mineral species at a locality).

Please note that you need to Save after editing each mineral entry - if you navigate to another mineral without saving, your changes will not be saved!

Type Locality

This allows you to specify whether a mineral at a locality is the type locality for that mineral – the type locality listings are for the worldwide type locality, not for regional type localities. As most of this information for known minerals has already been documented, this is not likely to be needed unless you are entering a newly recognized mineral to the database. If you think there is an error in the type locality listing, please post a message in the Errors section of the Messageboard.

Delete this Entry

This function should only be used when a mineral has been added to a locality by mistake. Minerals added from a reference that have since been disproven should not be deleted: instead, change the confirmation status to "erroneously reported."


This allows you to indicate the confirmation status of a mineral at a locality:

  • Confirmed - indicates a mineral is confirmed. Confirmed minerals should be distinguished by method of confirmation whenever possible (hold control and click to select multiple methods).
  • ? Unconfirmed - designates that a mineral has not been definitively confirmed or is questionable for some reason.
  • Erroneously reported - designates that a mineral occurrence has been previously published erroneously. In this situation, you should provide both the original (erroneous) reference, as well as the publication indicating the error. If the mineral was incorrectly identified, the correct mineral should be listed in the comment section. If the source for an erroneous report was not listed, the entry may be deleted entirely.
  • Never found but inferred to have existed in the past - designates that a mineral is no longer present at a locality, but that there is evidence for it having existed at some point in geologic time; an example of usage of this designation would be listing pyrite in a deposit where 'limonite' after pyrite is found, but never any samples of pyrite.

Confirmation reference ID can be used to reference an analysis performed by an institution. If the analysis includes a reference ID number, it can be entered here.

Methods allows the specification of the methods that were used in the confirmation of a species at a locality. Multiple methods can be selected from the list by holding command on a Mac or ctrl on a PC while clicking the items.

Classification(s) of Formation

This section allows for detail regarding the classification of a mineral occurrence, as well as the quality of specimens.

Classification of a mineral occurrence indicates the type of formation of a mineral at a deposit. One or more of these classifications can be checked.

  • Primary indicates original minerals in a deposit.
  • Secondary those minerals formed through alteration of primary minerals.
  • Post-mining/Anthropogenic applies to minerals formed only in situations created by mining or other human activity.

Quality for species

This section can be used to designate the quality of specimens of a mineral at the locality. This can be set at any of the following rankings:

  • Rock forming mineral/non-crystalline/little interest for collectors
  • Poor for species, only of interest for locality collectors
  • Not specified/average specimens [default]
  • Good crystals or rich for species – important
  • Excellent – world class for species or very significant


This section can be used to designate the rarity of specimens of a mineral at the locality. This can be set to any of the following rankings:

  • Extremely rare: one known specimen or historical specimen(s) lost
  • Very rare: small number of specimens known
  • Rare: very infrequently found
  • Not specified/average [default]
  • Common: frequently found
  • Very common: significant amounts present
  • Extremely common: major deposit of primary rock constituent


This section can be used to designate a special significance of a mineral at a locality. This can be set to any of the following rankings:

  • No special significance [default]
  • Significant commercial deposit of this mineral (past or present)
  • "Dana Locality" - A locality listed in 19th century editions of Dana's "System of Mineralogy"
  • Other classic locality for this mineral (please cite suitable reference)
  • Unusual or interesting association, relationships with other species, pseudomorphism, etc.


For miscellaneous information that does not fit any of the existing categories. This can include specific areas within a locality that a mineral is found, any historical information about the mineral species at the locality, if the mineral pseudomorphs another species, etc..

It may be useful to fill in the information in the categories below to determine which information does not fit anywhere else.

Crystal Habit(s)

The details regarding a mineral's crystal shapes (tabular, acicular, platy, equant, etc.), sizes, and details of aggregate habits (druzy, stellated, etc.) at a locality can be added here.


The details of color or range of color of a mineral at a locality can be added here.

Luminescent Properties

Any luminescent properties displayed by a mineral at a locality can be added here. This information should include the color of fluorescence as well as the type of activation energy – for example, “red in SW and blue-green in LW”. Frequently used abbreviations are as follows:

  • SW – shortwave UV
  • LW – longwave UV
  • MR – mid-range UV
  • X-Ray – x-ray
  • GAL – gas argon laser

This section can also be used for details regarding phenomena such as phosphorescence, triboluminescense, and cathodeluminescence.

Special Display/Storage Requirements

This section is to note any type of special display or storage requirements for a mineral from a locality. This may include protection from UV light, humidity, or other factors that may be important in preserving a specimen.


Chemical or age analysis of samples can be added here.


Any previously added references will be listed here. You can use this area to add additional references concerning a mineral at a locality (this can also be done in bulk as described above under Adding New Minerals/Rocks.

When you are finished adding information to a mineral, you need to save your changes.
You can choose to Save Changes, which will save and refresh the page, or Save & Go to Locality Entry or Save & Go to Locality Page, which will save and redirect you as indicated.

Please note that you need to Save after editing each mineral entry - if you navigate to another mineral without saving, your changes will not be saved!
