文摘
- •
Aeromagnetic data evidence dominant regional NNW-SSE structures.
- •
The root of the Tinguicht pluton is not deeper than 5–6 km.
- •
Magnetic fabric shows transpressional emplacement conditions for this Yetti pluton.
- •
These conditions are similar to those for the contemporaneous Eglab Drissa pluton.
- •
A model has been developed for the evolution of the Tinguicht pluton.
