Geochemistry of ore, host rock, and mine waste pile samples of iron oxide-apatite (IOA) deposits of the eastern Adirondack Highlands, New York, in relation to potential rare earth elements resources, 2016-2018 Thirty-four ore, twenty-nine mine waste, seven host rock, two pegmatite, and one slag sample were collected from iron oxide-apatite (IOA) mines in the eastern Adirondack Highlands near Mineville and Ticonderoga, New York, from March 2016 to August 2018. The waste pile samples included twenty-five samples collected from rubble-sized mine waste piles and four samples from processed tailings piles. The ore from historic iron mines of the eastern Adirondack Highlands, New York, contain abundant quantities of rare earth element (REE)-bearing apatite crystals. These apatite crystals are especially enriched in Y, La, Ce, and Nd. In-ground ore, mine waste piles, and tailings piles could contain apatite...

Calcite geochemical data was collected using electron microprobe and laser ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS) analyses. Reported whole-rock data was measured by inductively coupled plasma-optical emission spectrometry (ICP-OES), inductively coupled plasma-mass spectrometry (ICP-MS), ion selective electrode-fluoride (ISE-F), and wavelength dispersive X-ray fluorescence (WDXRF). Geochemical data are presented in downloadable .csv files. Spatial data of sample collection sites are provided as polygons in...
