Authigenic grey monazite from ordovician metasediments of the Iberian massif: the Matamulas placer
Mineralium DepositaAuthigenic nodular monazite occurs in dark, Middle Ordovician, low-grade metapelites of the Central Iberian and West Asturian-Leonese Zones of the Iberian Massif. Erosion of monazite-bearing slates and phyllites, and short-range transport resulted in localised recent alluvial deposits rich in millimetre-size monazite, of which the Matamulas site ...

Strontium isotopes are consistent with low‐elevation foraging limits for Henst's goshawk
Wildlife Society Bulletin, 2017 Apex predators play critical roles in the ecosystems they inhabit. Unfortunately, little is known about movement patterns for many species. This information is critical for evaluating vulnerability to habitat loss and the adequacy of existing or proposed
