Description and terrestrial ages of the Calama Area Meteorite Collection (Atacama Desert, Chile)

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We present a comprehensive study of a meteorite collection from the Atacama Desert (Chile), the driest and most climatically stable desert in the world. This collection includes meteorites from three adjacent Dense Collection Areas (DCAs) in the northern part of the Atacama Desert: Calama, Sierra Gorda, and Chug Chug, referred to as the ...

The Form of Agency

open access: yesNoûs, EarlyView.
ABSTRACT Philosophers often think agency is essentially connected with rationality, intention, or control. However, Minimalists argue that agency is just the power to cause a change; acids and boulders are agents too. Many philosophers treat Minimalism as a wild outlier, assuming its falsity without argument.

The Impact Of Meteors [PDF]

open access: yes, 1936
Energy changes that occur when a meteor strikes the surface of the earth or the moon, are difficult to determine. The velocity of meteors is so much greater than that of molar masses with which we are familiar, such as projectiles of high powered rifles,

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

open access: yesSedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...

Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment

open access: yesTerra Nova, EarlyView.
ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...
