Geochemistry and tectonic significance of augen gneisses from the southern Menderes Massif (West Turkey)
Article Abstract:
Western Turkey's Menderes Massif contain protoliths of mylonitized augen gneisses in its southern sector. These protoliths, or leucogranites, cut through the metamorphic rocks that were formed between the early Eocene and early Oligocene. In addition, the protoliths intrude on the metamorphic basement rocks in the massif's schist envelope. Studies suggest that the protoliths were formed from a water-saturated melt and emplaced during the late Oligocene when the thickened crust was subjected to a late-orogenic extensional collapse.

Discussions of cathodoluminescence of recent biogenic carbonates: an environmental and ontogenetic fingerprint
Article Abstract:
The usefulness of cathodoluminescence in the study of modern biogenic carbonates was presented. This property is believed to be the result of post-depositional precipitation or recrystallization processes undergone by reefal carbonates. A contrary view was held by a group of scientists, stating that while recent biogenic carbonate skeletons exhibit luminescence it is not always a result of diagenesis and that such properties of modern animal skeletons reflect on the environmental conditions during the animals' lifespan.
