Numerous inselbergs rise above the regional erosional surface in semiarid northeastern Brazil. The are underlain by Quixadá Pluton and cut cm-thick granite dike swarms. Five with abundant dikes from two different parts of pluton were selected to investigate role patterns evolution residual topography, including morphological features hillslopes. methods included field mapping landforms, structu...

Abstract We report a new zircon U–Pb age of 1257 ± 6 Ma for the Punugodu granite (PG) pluton in Eastern Dharwar Craton (EDC), Southern India. The Mesoproterozoic PG is alkali feldspar hypersolvus emplaced at shallow crustal level, as evident from presence rhyodacite xenoliths and hornfelsic texture developed metavolcanic country rocks Neoarchaean Nellore Schist Belt (NSB). Geochemically, metalu...

Abstract Many porphyry molybdenum deposits are hosted in multi-phase plutons, but it is unclear some how these magmas originated and whether the pluton intruded as fractionated or was by new batches of magma. New mapping has clarified field relationships between units White Pine Mo system Little Cottonwood stock, Utah (western United States), including intrusion, Red porphyry, rhyolite dikes, p...

Abstract One of the most important processes heat generation from Earth's interior is radioactive decay isotopes. The main hosts major radiogenic elements U, Th and K in crust are granitoids. Sierras de Córdoba formed dissimilar granitic intrusions emplaced by a series magmatic events that occurred during Paleozoic. different granitoids classified as A-type, I-type, S-type, there also expressio...

Abstract Plutons offer an opportunity to study the extended history of magmas at depth. Fully exploiting this record requires ability track changes in magmatic plumbing systems as magma intrudes, crystallizes, and/or mixes through time. This task has been difficult granitoid plutons because low sampling density, poorly preserved or cryptic intrusive relationships, and difficulty identifying plu...
