2190-5053as old as 3.85 billion years, the formation and evolution of North China Craton is still controversial. Therefore this book will be of value to anyone interested in the evolution of cratonic blocks and Precambrian geology..978-3-662-52583-8978-3-662-45343-8Series ISSN 2190-5053 Series E-ISSN 2190-5061

Magmatic zircons have variable ε.(t) values from −5.5 to +7.7 with model ages of 3.92–2.57 Ga, of which most ε.(t) values are positive with a predominant peak of model ages at 3.4–3.1 Ga and a subordinate peak at 2.8–2.7 Ga. These Hf features reveal major juvenile crustal growth stages with si

Economic Theory and the Environmentgrowth rims document consistent metamorphic ages at ~2.50 Ga, suggesting the Yishui Complex experienced a regional granulite facies metamorphism at the end of the Late Neoarchean. Inherited detrital zircons also yield ages from 3.0 to 2.60 Ga and reaching peaks at 2.7–2.6 Ga, indicating an Early Neo

Petrogenesis of Neoarchean Basement in Shandong Province, = 30–45). They are generally enriched in light rare earth elements (LREE) and large ion lithophile elements (LILE), depleted in heavy rare earth elements (HREE), and high field strength elements (HFSE), with slight Eu anomalies. These geochemical features suggest that they were derived from partial
