Harper project area. During the 2022 field season, geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted 1:100,000-scale bedrock geologic mapping of ~2,600 mi2 (~6,700 km2) within the Eagle, Big Delta, and Mount Hayes quadrangles. The field area for the Mount Harper project covers an area from 50-60 miles northwest of Delta Junction, Alaska, and extends eastward into the Eagle Quadrangle 40-50 miles west of Chicken, Alaska. The project area is of current and historical interest for potential mineral resource development, including quartz vein gold (Au) mineralization, placer Au deposits, granite-hosted tin mineralization, and intrusion-related porphyry copper (Cu)-Au deposits. Mineral sites in and around the Mount Harper project area include Healy, the Pogo gold mine, Lucky 13, Eagle, and others. The data associated with this report are available in digital format as a comma-separated value (CSV) file. The data are available from the DGGS website: http://doi.org/10.14509/30963.The purpose of the Mount Harper project is to produce more accurate, detailed, and modern geologic maps and supporting datasets that will promote mineral resource exploration in eastern Interior Alaska.>station-descriptions: field station locations and rock magnetic measurements2022publication dateCompleteNone planned-146.995576-141.93648664.54816663.453082ISO 19115 Topic CategorygeoscientificInformationAlaska Division of Geological & Geophysical SurveysActinoliteAluminumAmphiboliteAnalysesAndalusiteAndesiteApatiteApliteArkoseArsenopyriteBasaltBatholithBedrockBedrock GeologyBrecciaCalciteCalciumCarbonatesCementChalcopyriteChemistryChertChloriteConglomerateCopperCorundumDGGSDaciteDiabaseDiopsideDioriteDolomiteDolostoneDomeDuniteEpidoteFeldsparFelsicFelsiteField NotesFoldingFoldsFractureFracturingGabbroGarnetGeologyGeophysical SurveyGneissGoethiteGoldGossanGraniteGranodioriteGraphiteGreenschistGreenstoneHarzburgiteHematiteHornblendeHornblenditeHornfelsIgneousIronKaoliniteKyaniteLamprophyreMagnesiumMagnetic SusceptibilityMagnetiteMalachiteManganeseMarbleMetamorphicMetamorphismMicaMineral AssessmentMineral DepositMineral DevelopmentMineral ExplorationMineral LocalitiesMineral ProspectMineral ResourcesMineralogyMineralsMiningMining ClaimsMolybdeniteMolybdenumMonzoniteMuscoviteMyloniteNephelineOrthogneissPegmatitePeridotitePhyllitePlagioclasePlutonicPorphyryPotassiumPumicePyritePyroxenitePyrrhotiteQuartzQuartziteResource AssessmentRhyoliteRocksSandSandstoneScheeliteSchistSedimentSedimentarySericiteSerpentiniteShearSideriteSilicaSillimaniteSilverSkarnSlateSodiumSphaleriteStauroliteStockworkStrainStructureSulfidesSulfurSurfaceSyeniteTalcTalusTectoniteTerraceTillTitaniumTonaliteTourmalineTrachyandesiteTrachyteTremoliteTrondhjemiteTuffTundraTungstenUltramaficVegetationVolcanicWehrliteWollastoniteAlaska Division of Geological & Geophysical SurveysBanner CreekBig DeltaBilly CreekBlack LakeBluff Cabin LakeBluff Cabin RidgeBoulder CreekBuckeye CreekBuckskin CreekBullion CreekCanyon CreekCedar CreekClear CreekClearwater CreekCopper CreekCorda CreekDelta CreekDelta JunctionDelta RiverDemocrat CreekDivide CreekEagleEagle CreekEnterprise CreekEva CreekFish CreekFish LakeFlag HillFlat CreekFourmile HillGeorge CreekGerstle RiverGold CreekGoodpaster FlatsGoodpaster RiverGranite CreekHarding LakeHartman LakeHealyHealy LakeHealy RiverHidden LakeIngle CreekIron CreekJoseph CreekJunction CreekKechumstukKechumstuk CreekKechumstuk MountainKeystone CreekLake GeorgeLake MansfieldLilliwig CreekLiscum SloughLogging Cabin CreekLost LakeMansfield CreekMansfield VillageMason NarrowsMichigan CreekMolly CreekMoose CreekMoose LakeMosquito CreekMount HarperNorvell CreekPogoPogo MinePorphyry CreekProgressive CreekQuartz LakeRapid CreekRhoads CreekRichardsonRosa CreekSalcha RiverSand CreekSand LakeSawmill CreekSerpentine CreekSevenmile CreekShaw CreekShaw PondTanana RiverTaylor CreekTaylor MountainTelegraph CreekTenderfoot CreekTenmile CreekThompson LakeTimberTomato CreekTwelvemile LakeVolkmar LakeVolkmar RiverWhite CreekWillow CreekWolf CreekWolf LakeYukon-Tanana UplandThis report, map, and/or dataset is available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).Any hard copies or published datasets utilizing these datasets shall clearly indicate their source.

Latitude and longitude are reported in the WGS84 datum.Location data - Location data for field stations were collected using GPS-enabled tablets or smartphones running the ESRI Field Maps app; the devices have a reported locational error between 10 and 12 m. Data were merged into an ArcGIS geodatabase. Latitude and longitude are reported in the WGS84 datum.2023Field rock descriptions - Field rock descriptions are composed of observations and interpretations made by project geologists in the field or in the field office, and may not be updated to reflect further observations, geochemical data, microscopic investigation, or other information. Field rock descriptions in this data file have not been reviewed for technical content and should be considered preliminary.2023Magnetic susceptibility measurements - Magnetic susceptibility measurements were collected using Terraplus KT-10 model handheld magnetic susceptibility meters. The KT-10 meters have a maximum sensitivity of 1 x 10-6 Syst\u00c3\u00a8me International (SI) units on smooth surfaces and a measurable susceptibility range between 0.001 x 10 3 and 1,999.99 x 10-3 SI. The values reported here are for individual measurements performed on representative surfaces of the sampled rock outcrops and/or hand samples. Up to 12 magnetic susceptibility readings were recorded at each field station. Efforts were made to avoid atmospheric effects by measuring multiple sides of outcrops and/or hand samples whenever possible. Where rock samples had been intensely weathered or sample material was not large enough to cover the coil of the KT-10 meter, magnetic susceptibility was not measured. These stations are presented with zero measurements for completeness.2023point.0000001.0000001decimal degreesWGS84WGS 846378137298.257223563rdf2023-6-station-descriptions.csv, rdf2023-6-station-descriptions-data-dictionary.csvfield station locations and rock magnetic measurementsDGGSstation-descriptionsAlaska Division of Geological & Geophysical SurveysMetadata Managermailing and physical
