Anhydrous minerals in asteroid Bennu: Evidence for well‐preserved primordial components
Abstract Aqueously altered carbonaceous astromaterials are dominated by secondary minerals, but a minor fraction of primary, anhydrous silicates and oxides escape alteration, offering insight into the original composition of asteroid parent bodies. We report the mineralogy, petrology, mineral chemistry, and oxygen isotopes of anhydrous minerals—50 ...

ABSTRACT Ibn Sīnā (c. 973‐1037), the Avicenna of Latin fame, developed a unique theory of the elements and their status in mixtures that severely challenged the views of earlier natural philosophers and in its turn was severely challenged by later Latin Schoolmen in the West.

Two-sided asymmetric subduction; implications for tectonomagmatic and metallogenic evolution of the Lut Block, Eastern Iran [PDF]
West directed subduction zones show common characteristics, such as low structural elevation, deep trench, steep slab and a conjugate back-arc basin that are opposite to those of the east directed subduction zones.
