It has been recognized for the past century that copper deposits, in common with those of many other metals, are heterogeneously concentrated in Earth’s upper crust, resulting in areally restricted copper provinces that were generated during several discrete metallogenic epochs over time intervals of up to several hundred million years.

The sizes of continental blocks, basaltic oceanic plateaus, and island arcs that would cause collisional orogenesis when they enter a subduction zone are calculated in an analysis based upon the assumption of local isostasy and the assumption that plate subduction is primarily driven by the negative buoyancy of the lithosphere.Seismic stratigraphy is the study of stratigraphy and depositional facies as interpreted from seismic data. Seismic reflection terminations and configurations are interpreted as stratification patterns, and are used for recognition and correlation of depositiona' sequences, interpretation of depositional environment, and estimation of lithofacies.The extracted heavy-mineral concentrates were sieved into four fractions: <0.1 mm, 0.1–0.25 mm, 0.25–0.5 mm, and >0.5 mm.

Abstract. The tectonic affiliations and magma compositions that formed Earth’s earliest crusts remain hotly debated. Previous efforts toward this goal have relied heavily on determining the provenance of Hadean zircons using low-dimensional discriminant diagrams developed from Phanerozoic samples, which are inadequate for capturing systematic ...

The generation of hydrous silicate magmas and subsequent separation of volatile-rich magmatic fluids with hydrothermal alteration are significant processes leading to the formation of porphyry deposits.Publication date: January 01, 1994.

The Central Asian Orogenic Belt (c. 1000–250 Ma) formed by accretion of island arcs, ophiolites, oceanic islands, seamounts, accretionary wedges, oceanic plateaux and microcontinents in a manner comparable with that of circum-Pacific Mesozoic–Cenozoic accretionary orogens.Palaeomagnetic and palaeofloral data indicate that early accretion …Southeastern Türkiye recently hosted two devastating earthquakes— M w 7.7 and 7.6—on 6 February 2023 (Fig. 1).The first earthquake (01:17:35 UTC; GEOFON) nucleated ∼20 km off the main strand of the East Anatolian fault zone (EAFZ) along a northeast–southwest‐oriented splay fault (Melgar et al., 2023; Okuwaki et al., 2023), after an 8–10 months period of elevated seismicity ...The continuation of the Mull Dyke Swarm into the Southern North Sea.

This water-filled sinkhole is the deepest known cave in the Bahamas, and the second deepest in the world, at 202 m. Although the processes linked with its formation are still unclear, its considerable depth might suggest a fracture of the bank margin.Although the reactions in Equations 1 and 2 appear similar, the contrasting implications are profound. The hydrothermal reaction imposes severe mass-balance limitations on the rate of reaction, the flux of CO 2 released, and even the absolute tonnage of skarn that can be generated by an intrusion of a given size (Lentz, 2005).This is …Aug 1, 2014 · The NGA-West2 project database expands on its predecessor to include worldwide ground motion data recorded from shallow crustal earthquakes in active tectonic regimes post-2000 and a set of small-to-moderate-magnitude earthquakes in California between 1998 and 2011.
