Mesoproterozoic
1000 - 1600 Ma



ID: 2950412
Leucogranitic (alaskitic) gneiss

Age: Mesoproterozoic (1000 - 1600 Ma)

Description: Sodic plagioclase ranges from generally subordinate to locally dominant; locally with biotite, hornblende, pyroxene, garnet, sillimanite, disseminated magnetite; commonly contains metasedimentary layers, amphibolite, migmatite; plagioclase-rich variety is host to magnetite ore bodies in eastern Adirondacks.

Comments: Original map source: NYS Museum, NYS Geological Survey, NYS Museum Technology Center, 1999, bedrock geology of NYS data is distributed in ARC/INFOr EXPORT format (with '.e00' extension) in 5 seperate files based on 1970 printed map sheets, scale 1:250,000.
