Theoretical petrology [PDF]

Reviews of Geophysics, 1979
The central issues in petrology have remained remarkably unchanged in the last 50 years. In igneous petrology, the focus is on understanding the nature and cause of diversity in igneous rocks: on identifying primary magma types and constraints on the ...

The Relationship between the Slope Hill and Bedrock with Some Soil Properties [PDF]

مجله آب و خاک, 2023
Introduction Changes in soil properties depend on factors such as climate, topography, landscape features, altitude, parent material, and vegetation. The quantity and quality of soils obtained from different rocks (igneous, sedimentary and metamorphic ...

Petrology and geochemistry of Eocene volcanic rocks from southeast of Khur (Isfahan province, Central Iran)

Journal of Economic Geology, 2022
Introduction Subduction-related magmas are characterized by enrichment of large ion lithophile elements (LILEs), light rare earth elements (LREEs) and depletion in high field strength elements (HFSEs) (Harangi et al., 2007). These geochemical signatures

Varying processes, similar results: How composition influences fragmentation and subsequent feeding of large pyroclastic density currents

Frontiers in Earth Science, 2022
Unlike their silicic counterparts, mafic eruptions are known for being on the low-end of the explosivity spectrum with eruption styles commonly ranging from effusive to Hawaiian fire fountaining.

Constraining Magma Reservoir Conditions by Integrating Thermodynamic Petrological Models and Bulk Resistivity From Magnetotellurics

Geochemistry, Geophysics, Geosystems, 2022
Magnetotelluric (MT) data image the bulk resistivity of the subsurface which can be used to infer magma reservoir conditions beneath volcanoes. The bulk resistivity of magma depends primarily on the melt volume fraction, temperature, and water content ...
