A database for igneous rocks of the Newfoundland Appalachians.

Databases are increasingly playing a pivotal role in the field of Earth Sciences. This paper presents a comprehensive database of igneous rocks from the Newfoundland Appalachians. The database comprises a collection of 15,202 datasets with a data analysis platform. Each dataset includes detailed information on geographic location (latitude and longitude), geological background, petrology, geochronology, major and trace elements, isotopes, and references. The data were compiled 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 data collected from diverse sources over a period of more than 50 years; and (3) an efficient platform for searchability and usability. This dataset is helpful to support a wide range of scientific research objectives related to igneous rocks in the Newfoundland Appalachians.
