In addition to descriptions of the material, the tabulated file includes geographic location, core hole numbers, an age estimate, core fragment depth, general lithology, grain size, and facies interpretation. The author examined these core materials in Fairbanks during winter and spring 2002. This work was done in preparation for an assessment carried out by the U.S. Geological Survey of undiscovered, technically recoverable hydrocarbon resources in the Yukon Flats basin.

The field team included Rick Stanley (USGS party chief), Jim Clough (DGGS), David LePain (DGGS), and Rocky Reifenstuhl (DGGS). Core samples belong to the Doyon Native regional corporation and, at the time of this writing, are stored in Fairbanks, Alaska. Doyon, Limited, gave DGGS permission to examine the core fragments. Mike Tolbert of Taiga Ventures provided core fragment layout space in the Taiga Ventures office in Fairbanks, and Chris Puchner introduced LePain to the core material. Funding for DGGS's work on this project was provided by the State of Alaska. Cross_Reference: Citation_Information: Originator: LePain, D.L. Originator: Stanley, R.G.

Dilute hydrochloric acid (HCl) was used to check for calcite and dolomite content. For each sample bag, the author provided a general rock type classification, noted the grain size range according to the Wentworth classification scale (Wentworth, 1922), provided a comprehensive description, and when possible, an interpretation of the depositional facies. In addition to descriptions of the material, the tabulated file includes geographic location, core hole numbers, an age estimate, core fragment depth, general lithology, grain size, and facies interpretation. The accuracy of the information transcribed from the sample bags (core hole numbers, an age estimate, core fragment depth) has not been verified by the author and is unknown. Logical_Consistency_Report: not applicable Completeness_Report: This data release is complete. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Paper copies of USGS topographic maps showing core hole locations were provided to the USGS by Doyon, Limited. Maps were scanned, imported into ArcGIS, and georeferenced by USGS staff to provide the latitude and longitude values (NAD27) of each core hole surface intercept. Location errors were not reported. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The subsurface depth of each sample was transcribed from sample bag annotations and presumed to be measured in feet below local ground surface. Lineage: Process_Step: Process_Description: Core observations - Core fragments where recovered from a series of core holes drilled by Exxon. Drilling crews placed core fragments in muslin sample bags marked with the core hole number, depth (feet), and estimated age of each core fragment. Some sample bags were annotated with additional location information, such as a stream name. Sample bags were grouped in cardboard boxes labeled with a box number and transported to an offsite warehouse for subsequent examination. A ten power (10X) hand lens and standard grain size comparator were used to examine core materials. Dilute hydrochloric acid (HCl) was used to check for calcite and dolomite content. For each sample bag, the author provided a general rock type classification, noted the grain size range according to the Wentworth classification scale, provided a comprehensive description, and when possible, an interpretation of the depositional facies.
