The anatomy of exhumed river-channel belts: Bedform to belt‐scale river kinematics of the Ruby Ranch Member, Cretaceous Cedar Mountain Formation, Utah, USA [PDF]

, 2020
Many published interpretations of ancient fluvial systems have relied on observations of extensive outcrops of thick successions. This paper, in contrast, demonstrates that a regional understanding of palaeoriver kinematics, depositional setting and ...

Significant enrichment of Ga, Rb, Cs, REEs and Y in the Jurassic No. 6 coal in the Iqe Coalfield, northern Qaidam Basin, China—A hidden gem

Ore Geology Reviews, 2017
Abstract This paper presents new data concerning the mineralogy and trace element geochemistry of the enriched rare metals in the Jurassic No. 6 coal from the Iqe Coalfield, Qaidam Basin, China. The conclusions of this study are based on new data and evidence that suggest the considerable enrichment of Ga-Rb-Cs-REEs and Y in the No. 6 coal of the Iqe

Bromsgrove Aquifer Groundwater Modelling Study : results from Task 1.1 3D visualisation and geological framework of the Bromsgrove Aquifer [PDF]

, 2009
The Bromsgrove Sandstone aquifer is over-abstracted. This has resulted in a long-term fall in groundwater levels, the reduction or loss of baseflow and the derogation of surface water features.
