This coverage includes arcs, polygons, and polygon labels that describe the generalized geologic age and type of surface outcrops of bedrock of the Far East (China, Japan, Mongolia, North and South Korea, and Taiwan; and parts of Cambodia, Laos, Thailand and Vietnam). It also includes shorelines and inland water bodies.

This coverage includes arcs, polygons, and polygon labels that describe the generalized geologic age and type of surface outcrops of bedrock of Southeast Asia (Brunei, Indonesia, Cambodia, Laos, Malaysia, Papua New Guinea, Philippines, Singapore, Solomon Islands and Vietnam; and portions of Australia, China and Taiwan). It also includes shorelines and inland water bodies.

This coverage includes arcs, polygons and polygon labels that describe U.S. Geological Survey defined geologic provinces of Southeast Asia (Brunei, Indonesia, Cambodia, Laos, Malaysia, Papua New Guinea, Philippines, Singapore, Thailand and Vietnam; and parts of Australia, China and Taiwan). Each province has a set of geologic characteristics distinguishing it from surrounding provinces. These characteristics may include the dominant lithologies, the age of the strata, and the structural style. Some provinces include multiple genetically-related basins. Offshore province boundaries are defined by the 2000 meter bathymetric contour.

From 2017-2019, framework metallogenic studies were completed in the eastern Yukon-Tanana upland in eastern Alaska. Numerous previously undated plutons known or suspected to contain components of porphyry, epithermal, and intrusion-related gold systems and associated deposit types were sampled for age and zircon trace element determinations between the Black Mountain area and the Yukon border, north of the Tanana River and south of the Yukon River. A collection of 54 samples were collected by Douglas Kreiner (USGS, Alaska Science Center). Zircon grains were separated from each sample. The samples were examined by U-Pb analysis by laser ablation-inductively coupled plasma mass spectrometry (LA-ICP-MS) in a USGS laboratory...

These data are for a geochronologic study of emplacement ages for plutons of the Cretaceous Idaho batholith and detrital zircon ages for metasedimentary rocks, west-central Idaho. Zircon from six samples of discrete plutons across a regional transect were dated by sensitive high resolution ion microprobe (SHRIMP). SHRIMP U-Pb ages of igneous rocks connect the igneous activity to structural history, crustal depths, and origins of epigenetic gold-silver-antimony-tungsten±mercury mineral deposits. Zircon from four samples of metasedimentary rocks in the southern part of the central Idaho mineral province were dated—three by laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) methods and one by SHRIMP...
