Secular Evolution of Continents and the Earth System
Reviews of Geophysics, Volume 60, Issue 4, December 2022., 2022 Abstract Understanding of secular evolution of the Earth system is based largely on the rock and mineral archive preserved in the continental lithosphere. Based on the frequency and range of accessible data preserved in this record, we divide the secular evolution into seven phases: (a) “Proto‐Earth” (ca. 4.57–4.45 Ga); (b) “Primordial Earth” (ca. 4.45–

Review on geology and mineralization of North Korea (I: Precambrian)
Resource Geology, Volume 71, Issue 4, Page 492-513, October 2021., 2021 The Precambrian geotectonic provinces of North Korea contain continental cores and massifs, active continental margins, and rift zones. The Precambrian strata between the eastern North China Craton (NCC) and North Korea are newly correlated considering rearranged stratigraphy in this review.

Terra Nova, Volume 33, Issue 5, Page 502-510, October 2021., 2021 Abstract Fault‐ and fracture‐hosted multi‐stage mineral assemblages that formed by fracture reactivation and fluid migration, constitute archives of the tectonic evolution of Precambrian cratons. Complex intergrowth patterns of these mineral records often hinder absolute dating of mineralization events for geological models.

Plagioclase-mantled K-feldspar in the Carboniferous porphyritic microgranite of Altenberg-Frauenstein, Eastern Erzgebirge / Krušné Hory [PDF]
Bulletin of the Geological Society of Finland, 2002 The Upper Carboniferous porphyritic microgranite of Altenberg-Frauenstein, formerly known as Granitporphyr (Dalmer 1896) and here abbreviated as GP, forms a 36 km long and up to 18 km wide complex of ring dykes related to the Teplice-Altenberg caldera in

Crustal development in relation to granitic magmatism in regard to D/H partition between coexisting hornblende and biotite in the Svecofennian belt [PDF]
Bulletin of the Geological Society of Finland, 1993 Tie-lines in the σD-XFe diagram of hornblende and biotite in Japanese island arc granites give commonly a similar slope to that derived from the equation of Suzuoki-Epstein's experimental work (1976).

Geochemistry of Xenoliths in Rapakivi Granites of the Korsun-Novomyrhorod Pluton (Ukrainian Shield)
Mineralogical Journal, 2023 Rapakivi of the Korsun-Novomyrhorod pluton (KNP), being the latest Precambrian granites of the central part of the Ukrainian shield, contain older acidic and intermediate rocks as xenoliths, the geochemical features of which reflect the Early Proterozoic

The rapakivi granite plutons of Bodom and Obbnäs, southern Finland: petrography and geochemistry [PDF]
Bulletin of the Geological Society of Finland, 1999 The Obbnäs and Bodom granite plutons of southernmost Finland show the typical petrographic and geochemical features of the Proterozoic rapakivi granites in Finland and elsewhere: they cut sharply across the 1900 Ma Svecofennian metamorphic bedrock and ...

Anorogenic granitoids of the Early Precambrian magmatism of the Ukrainian shield [PDF]
Bulletin of the Geological Society of Finland, 1993 The Early Precambrian magmatism of the Ukrainian shield evolved through regular changes in tectonic setting, composition and depth of formation of rocks of three magmatic associations: (1) granitic, (2) diorite-granitic and (3) anorthosite-granitic. They

Amphibole: A major carrier of helium isotopes in crustal rocks [PDF]
, 2016 The first evidence for a specific role of amphiboles in He isotope balance of crustal rocks was presented in early contributions by Gerling et al. (1971, 1976).

Rare metal granites and related rocks of the Ukrainian shield [PDF]
Bulletin of the Geological Society of Finland, 1993 Two rare metal leucocratic granites, Perga and Kamennaya complexes, can be distinquished on the Ukrainian shield. The Perga complex consists of medium- and coarse-grained, mainly porphyric, biotite, riebeckite and aegirine granites, granite porphyries ...
