Late Neoproterozoic layered mafic intrusion of arc-affinity in the Arabian-Nubian Shield: A case study from the Shahira layered mafic intrusion, southern Sinai, Egypt

Geologica Acta, 2016
The Shahira Layered Mafic Intrusion (SLMI), which belongs to the late Neoproterozoic plutonic rocks of the Arabian-Nubian Shield, is the largest layered mafic intrusion in southern Sinai.

Understanding the feasibility of pit lakes for tailings disposal and CO2 sequestration

Discover Geoscience
The pit lakes and tailings are one of major source of acid mine drainage (AMD) and metal contamination in the mining landscapes. The dissolution of metals from pit lakes in the close proximity to aquifers contaminate groundwater in the downstream.

Crust‐Mantle Interaction During Continental Deep Subduction: Evidence From Light Mo Isotopes in Post‐Collisional Mafic Igneous Rocks From the East Kunlun Orogen

Geochemistry, Geophysics, Geosystems
It is intriguing whether and how crust‐mantle interaction would proceed in continental subduction zones. Here, we report zircon U‐Pb ages and Hf isotopes, major and trace elements, and Sr‐Nd‐Mo isotopes for Late Paleozoic mafic igneous rocks from the ...

Phase equilibria constraints on the stability of garnet in mafic granulite: An example from Karimnagar granulite terrain, Eastern Dharwar Craton, India

Evolving Earth
Phase equilibria modeling becomes a widely accepted tool to constrain the P-T conditions experienced by the metamorphic terrain because of its advantage over the earlier methods e.g., conventional methods and petrogenetic grids.
