Thermal Buffering, Heat Advection and Crustal Thinning in the Ryoke Metamorphic Complex, Yanai, Southwest Japan

Journal of Metamorphic Geology, EarlyView.
ABSTRACT The metamorphic zoning and geothermobarometry of the Ryoke metamorphic complex in the Yanai area, southwest Japan, show that its thermobaric structure was buffered by the dehydration melting of biotite. The temperatures over most of the area covered by the three high‐grade zones (8.5‐ to 19.0‐km depth) are consistent with those of the ...

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

Geophysical assessment of subsurface conditions at proposed building sites: implications for foundation failure and building collapse [PDF]

, 2018
Building collapse has been a recurrent environmental hazard in Nigeria in the last two decades. This is a corollary of inadequate foundation investigation prior to construction, poor government policies, and general lack of awareness on the importance of

Coesite Discovery in Eclogites Confirms UHP Metamorphism in the Orlica‐Śnieżnik Dome (SW Poland)

Journal of Metamorphic Geology, Volume 44, Issue 3, Page 200-225, April 2026.
ABSTRACT Eclogite lenses are exposed within the orthogneiss‐dominated core of the Orlica‐Śnieżnik Dome in the Sudetes, which forms the northeastern margin of the Bohemian Massif (Variscan Belt of Central Europe). The presence of coesite inclusions in garnet and omphacite confirms that these eclogites underwent ultrahigh‐pressure metamorphism.
