There is growing evidence that many magmatic systems are transcrustal in nature (Cashman et al., 2017).Physical models point to the transient nature of shallow magma chambers, and geochemical data show evidence for long (>103–105 yr) residence times before more rapid mixing and eruption events (Sparks and Cashman, 2017; Costa …Read Volume 2022 Issue Special 12 of Lithosphere.

Windfall is a world-class Archean intrusion-related Au deposit (7.4+ Moz of Au) located in the underexplored Urban-Barry greenstone belt (Quebec, Canada).Determining the age of siliciclastic continental sequences in the absence of comprehensive biostratigraphy or radiometric dating of geological markers (e.g., volcanic layers) is inherently challenging.View article titled, Transformations of borehole magnetic data in the frequency domain and estimation of the total magnetization direction: A case study from the Mengku iron-ore deposit, Northwest ChinaThis volume was derived from a symposium, Tectonics and Sedimentation that was held at the AAPG/SEPM Annual Meeting in Anaheim, California on May 15, 1973.Publication date: January 01, 2008. Migmatites are highly heterogeneous rocks found in high-grade metamorphic environments; they are commonly encountered in the continental crust. Until now, many geologists have been deterred from working with migmatites because of their complex appearance and an unhelpful non-genetic nomenclature. In his Atlas ...
