Inventory of Onshore Petroleum Seeps and Stains in Greenland

The dataset comprises a systematic inventory of onshore petroleum seeps and stains in Greenland. The inventory includes information on approximately 130 localities distributed across Palaeozoic, Mesozoic and Cenozoic sedimentary basins in Greenland. For each locality, coordinates, site descriptions, classification of seep type, geological context, sample numbers and references to reports and publications are recorded.

The classification includes oil seeps, gas seeps, mud diapirs and gas-rich springs, oil stains in volcanics, carbonates and sandstones, solid macroscopic bitumen, and fluid inclusions and other evidence of micro-seepage.

The dataset synthesises existing knowledge of petroleum systems in Greenland and provides a comprehensive overview of documented natural hydrocarbon occurrences onshore.

Purpose
The purpose of the dataset is to support research and exploration activities by compiling and structuring documented occurrences of natural hydrocarbons onshore in Greenland. The inventory has been developed to facilitate new geological investigations and to improve the understanding of petroleum systems, including source rock distribution, migration, accumulation and degradation processes.

Supplemental Information
The dataset represents documented and published observations of petroleum seeps and stains and does not constitute a complete inventory of all potential hydrocarbon occurrences in Greenland. Locality classifications and geological interpretations are based on available documentation at the time of registration and may be revised as new information becomes available.

Dataset
Statement
The dataset has been compiled from published scientific articles, internal and external reports, and field observations collected during decades of geological investigations in Greenland. Information on localities, classification and geochemical analyses has been systematised and harmonised within a unified database. More than 400 samples have been analysed geochemically or described microscopically. The inventory is designed for continuous updates with additional localities, descriptions and new organic geochemical data.
