Establishing geothermometric constraints on the local geothermal gradients: Case study of the Eastern Cordillera Basin, Colombia

Geodesy and Geodynamics, 2018
Geochemical analyses were performed on 170 coal bed-trapped groundwater samples from 97 underground mines located in the Eastern Cordillera Basin, Colombia. The waters analyzed in this paper are from exploited coal beds, located up to 0.73 km deep, which

Estructuras tectónicas en el frente meridional de la Cordillera Cantábrica entre los ríos Curueño y Porma [PDF]

, 2022
El frente meridional del relieve de la Cordillera Cantábrica coincide con el frente de deformación alpino. Además de la presencia de un cabalgamiento principal, responsable del levantamiento de la cordillera, existen otra serie de estructuras menores ...

Balancing mechanics and metabolism: Elevational variation in the microanatomy of hummingbird flight muscle

The Anatomical Record, EarlyView.
Abstract Factors varying along elevational gradients impose strong aerodynamic and physiological constraints on powered flight, yet the internal microanatomical variation associated with elevational context in animals under such conditions remains poorly understood.

Climatic thresholds and temporal decoupling drive reproductive phenology in Neotropical cloud forests: a 36‐year analysis

Ecography, EarlyView.
Reproductive phenology influences ecosystem functioning and climate sensitivity in tropical montane cloud forests, but phase‑specific climatic thresholds and the temporal coupling between flowering and fruiting remain poorly quantified over decadal scales. We analyzed a 36‑year monthly record (1983–2018) from a Venezuelan cloud forest (15 focal species)

Characteristics of Boundary Layer Height Variations in Global Arid Regions and Their Sensitivity to Influencing Energy Factors

International Journal of Climatology, EarlyView.
Global warming has intensified drought impacts across most arid regions, altering surface energy partitioning and atmospheric boundary layer (ABL) development. Using 1979–2018 ERA‐Interim reanalysis data, we show that the long‐term mean boundary layer height (BLH) over global arid regions is approximately 841.8 m, nearly 200 m higher than over humid ...

Deformacion compresiva cuaternaria en la Cordillera Principal de Chile central (Cajon del Maipo, este de Santiago).Quaternary compressional deformation in the Main Cordillera of Central Chile (Cajon del Maipo, east of Santiago).

Andean Geology, 2008
A detailed study of recent sediments in the Maipo River Valley (Cajon del Maipo), east of Santiago, shows a compressive deformation documented by coeval reverse faults and drag-folds. These structures are characteristic of a principal stress direction trending roughly N-S (N338 degrees E) that also affects the older sediments of the Abanico Formation ...
