TL;DR: In this paper, the authors describe a complex interplay between formational and preservational forces that, in turn, largely reflect changes in tectonic processes and environmental conditions in an evolving Earth.

TL;DR: In this article, the authors presented new high precision in situ sensitive high-resolution ion microprobe (SHRIMP) U-Th-Pb and laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) ages for hydrothermal monazite from the largest of the Jiaodong gold deposits, which were previously dated as indicating ore formation over a few tens of millions of years.

TL;DR: In this article, turbidite-hosted gold deposits in the southern Alaska accretionary prism are the same age as nearby near-trench plutons and gold lodes formed above a slab window during subduction of an oceanic spreading center.

TL;DR: In this paper, the authors present 40Ar/39Ar dates for muscovites from quartz veins along a major shear zone in southeast Alaska, which show that the veins were emplaced in the early Eocene, during the late stages of orogenic deformation.

TL;DR: The Dongping gold deposit as mentioned in this paper is located about 200 km inboard of the northern margin of the North China craton and is mainly hosted by syenite of a middle Paleozoic alkalic intrusive complex that was encountered into Late Archean basement rocks.
