Titanium-vanadium deposits hosted in mafic-ultramafic layered intrusions and massif anorthosite intrusions from around the world This data release includes four .csv files and one Esri shapefile which contain data on titanium-vanadium deposits hosted in mafic-ultramafic layered intrusions and massif anorthosite intrusions from around the world. Some of the data was used to create a grade and tonnage model for titanium-vanadium deposits hosted in mafic-ultramafic layered intrusions. Only deposits with reported grade and tonnage information were included in this data compilation. The Titanium_vanadium_deposits.csv and Titanium_vanadium_deposits.shp files list the deposits and associated information such as the host intrusion, location, grade, and tonnage data, along with other miscellaneous descriptive data about the deposits.

These shorelines are compiled and analyzed in the Digital Shoreline Analysis System software (v5.1) to compute their rates of change. Keeping a record of historical shoreline positions is an effective method to monitor change over time, enabling scientists to identify areas most susceptible to erosion or accretion. These data can help coastal managers understand which areas of the coast are vulnerable to change. This data release, and other associated products, represent...
