ecollectionevents > Volcano (1)
This tab contains information about the volcano that produced a given igneous rock, including eruption dates. Information recorded on this tab should use the identifiers, names, and events defined by the Global Volcanism Program (GVP) .

Volcano Number |
A numeric identifier assigned to volcanoes active in the Holocene or Pleistocene in the GVP database
Usage
Required if volcano name is populated. For volcanoes older than the Pleistocene, use “–“.
Format
A six-digit number corresponding to a volcano in the GVP database. Names and numbers are checked for consistency annually by the data manager.

The name of a volcano from the GVP database that produced the sampled material
Usage
Required if volcano number is populated.
Format
Name should exactly match the format used on the GVP website. If the collection materials use a synonym, record the preferred name instead.
The Holocene and Pleistocene volcano lists provded by GVP use an inverted format that omits diacritics that appear on the website. For example, “Île de la Possession” is rendered as “Possession, Ile de la”. Use “Île de la Possession”. Refer to the GVP website to verify diacritics.
GVP omits “Mount”/”Mt” from volcano names, so use “Rainier” (not “Mt. Rainier”) and “St. Helens” (not “Mt. St. Helens”). This practice is not consistent across languages, however. For example, Japanese volcano names in GVP include -san and -yama suffixes that serve a similar purpose.
GVP includes large features, like volcanic fields and calderas, that may include named vents that are themselves referred to as volcanoes in collection materials. Parícutin, for example, is classified by GVP as a subfeature of Michoacán-Guanajuato. Subfeatures should be recorded in the Subfeature field.

The name of a cone, vent, or other volcanic feature from the GVP database that produced the sampled material
Usage
Omit if no appropriate data is available
Format
Name should exactly match a volcanic feature from the GVP database. Note that some subfeatures defined by GVP are well-known stratovolcanoes in their own right. For example, Sakurajima is classified as a feature of the Aira caldera.
