A database for igneous rocks of the Newfoundland Appalachians

Databases are playing an increasingly pivotal role in the field of Earth Sciences. We present a comprehensive database of igneous rocks from the Newfoundland Appalachians (https://dde.igeodata.org/subject/detail.html?id=67). The database consists of a set of 15,110 high-quality data. Each dataset includes detailed information on geographic location (latitudes and longitudes), geological background, petrology, geochronology, major and trace elements, isotopes, and references. The data were collected from published papers, publicly available databases, geological survey reports, and academic dissertations. The database offers several advantages: (1) A systematic and complementary data model aligned with the knowledge systems of igneous rock. (2) A broad range of high-quality data collected over 50 years, and derived from diverse sources; (3) A platform for efficient searchability and usability. This database will help achieve a wide range of scientific research objectives related to igneous rocks in the Newfoundland Appalachians and the tectonic evolution of the Newfoundland island.
