EPS 145/245 Introduction to Igneous Petrology and Petrogenesis

Class

How igneous rocks form and reveal the processes and fluxes involved in the circulation of the solid Earth. The course begins with the essential elements of igneous petrology, rock description and nomenclature, mineralogy, phase diagrams, processes of...

Petrological systematics of the Mid-Atlantic Ridge south of Kane: Implications for ocean crust formation

Journal Article

Models of ridge segmentation, mantle flow and melt focusing predict how the chemical compositions of mantle melts should vary along a mid-ocean ridge axis. The compositions of basaltic lavas can be compared to these predictions to test the models. Such...

Depth versus age: new perspectives from the chemical compositions of ancient crust

Journal Article

Petrological data provide a new approach to an evaluation of the depth–age problem for ancient seafloor. The correlations among basalt chemical composition, axial depth and mantle temperature at current ocean ridges allow the determination of initial...

A global geochemical database structure for rocks

Journal Article

This technical brief describes a geochemical and petrological database structure based on the relational model that has broad applicability to chemical analyses of geological materials. Notable features of the database structure are its comprehensiveness...

Ridge subduction and fore-arc volcanism: petrology and geochemistry of rocks dredged from the western Solomon arc and the Woodlark Basin

Petrology and geochemistry of lavas from the Sumisu and Torishima backarc rifts

Journal Article

Thirteen dredge hauls from the active Sumisu and Torishima rift grabens west of the Izu-Bonin arc at about 30°–31°N, 140°E, recovered a suite of tholeiitic basalts to sodic rhyolites. Volcanism occurs along tensional faults within and bounding the rift...

Petrology and Sr, Nd, and Pb isotope geochemistry of mid-ocean ridge basalt glasses from the 11°45′N to 15°00′N segment of the East Pacific Rise

Journal Article

Basaltic glasses from the geophysically well-studied section of the East Pacific Rise (EPR) between 11°45′N to 15°00′N range from normal mid-ocean ridge basalts (MORB) to transitional MORB and their major element variations correlate with isotopic and...
