XXI. On the Rocks and Graptolitic Shales of the Moffat District [PDF]

Transactions of the Geological Society of Glasgow, 1882
Having on several occasions described the rocks of Moffatdale to the Society, I shall confine my remarks to-night to a few minor details connected with them, aided by a number of hand specimens I have brought for illustration. It may safely be asserted that few other stratified rock formations have undergone such an upheaving, crushing, and contorting,

Influence of water-rock interaction on stress sensitivity of organic-rich shales: A case study from Longmaxi formation in the southeast area of Chongqing

Youqicang pingjia yu kaifa, 2019
The production of shale gas is a complex and multiscale process that spans a variety of scales and goes through a variety of mass transfer mode. The stress sensitivity of each path has an important influence on the mass transfer of shale gas.

Iowa Population Exposures to Metals and Metalloids in Well Water

Environmental Toxicology, EarlyView.
ABSTRACT Previous Iowa studies suggest low levels and chronic arsenic exposures are associated with prostate cancer. The rural Iowa population heavily relies on private wells for drinking water resources and thus is vulnerable to contaminants such as heavy metals found in well water.

The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

Integrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...
