The Mesozoic was also a time of major geologic change during which great thicknesses of rocks were deposited across the western US. See Chapter 3: Fossils

Three major terranes comprise the Blue Mountains composite terrane in Idaho. These are Permian to Triassic fragments of oceanic island arcs, continental fringing arcs, and various subduction-related mélange that were amalgamated, and underwent Late Triassic metamorphism and Triassic-Jurassic sedimentation, before collision with the North American margin.

They resulted from the collision of the African and Laurasian plates during Mesozoic and Tertiary times. The high standard of knowledge attained over the last 30 years by the working groups on "Alpine Metamorphism" is well known and helped considerably to recognize pre-Mesozoic elements in the Alps.

The Mesozoic–Cenozoic geology of SE China is characterized by extensive magmatism, contractional and extensional deformation related, large-scale structures (i.e. SE China fold-and-thrust belt, Xuefeng Uplift, East China Rift System, Yangtze Fold Zone) and strike-slip fault systems (Figs 1, 2). A.R. Milner, in Encyclopedia of Geology, 2005 Introduction. In the Mesozoic, the various amniote groups (reptiles, birds, mammals, and their earlier relatives) came to dominate terrestrial niches; the fossil records of this era depict a general decline of the archaic amphibian groups and diversification of the modern amphibian groups. Hf isotope compositions of magmatic zircon grains from igneous rocks in the Liaodong Peninsula indicate that widespread late Mesozoic granitoids formed by partial melting of ancient crust, but with significant input of a mantle component via magma mixing and crustal assimilation. Mesozoic definition, noting or pertaining to an era occurring between 230 and 65 million years ago, characterized by the appearance of flowering plants and by the appearance and extinction of dinosaurs. Pre-Mesozoic Geology of Iberia is a major reference for current understanding of the overall tectonostratigraphic evolution of the Iberian Massif.

Instead, they have been eroded in places by relatively recent geologic activities, particularly during the Ice Age that began about two million years ago. They resulted from the collision of the African and Laurasian plates during Mesozoic and Tertiary times. The high standard of knowledge attained over the last 30 years by the working groups on "Alpine Metamorphism" is well known and helped considerably to recognize pre-Mesozoic elements in the Alps.

The geology of Estonia is the study of rocks, minerals, water, landforms and geologic history in Estonia. The crust is part of the East European Craton and formed beginning in the Paleoproterozoic nearly two billion years ago.

Book Material. Published material. Publication info Memoir 49 This volume presents a set of research papers that provide new data and interpretations of the Permian–Triassic terranes of SE Gondwana, now exposed in South Island, New Zealand. Following an introduction for general readers, a historical summary and a review of biostratigraphy, the individual papers primarily focus on the Permian magmatic arc of the Brook Street Terrane, the 2011-01-14 Since 1988, Nancy McHone and I have made five brief visits to Grand Manan Island. From the first, it has been apparent to us that the spectacular exposures of basalts on Grand Manan deserve much more attention. Our examinations of the Mesozoic rocks and structures as described in this paper are essentially reconnaissance, but we intend to conduct more serious mapping sessions during the next Pre-Mesozoic Geology of Iberia is a major reference for current understanding of the overall tectonostratigraphic evolution of the Iberian Massif.
