A core taken in 1993 from the modern saltpan at Badwater Basin in Death Valley, California, USA recovered about 185 m of saline lacustrine sediments. The sediments reflect climate fluctuations during the last 200 ka, encompassing two major glacial-in

Analyses of fluid inclusions in halite allow direct comparison of ancient surface temperatures and those from modern environments. These data provide a means of assessing the absolute magnitude of past temperature changes. Modern salt pans on the flo

While clastic mudstones and shale were traditionally interpreted to have been deposited in quiet water settings, recent flume experiments and studies have shown that mud can be transported in and deposited by traction currents as migrating ripples of

Reservoir upgrading of bitumen and heavy oils may involve the use of moderate to high temperatures (200–350 °C). In the absence of an efficient catalyst that could help split or transfer hydrogen to cracked heavy molecules, these would deteriorate

The bitumen of the Lower Cretaceous McMurray Formation in Alberta arguably represents one of the most important hydrocarbon accumulations in the world. In-situ development relies on heat transfer through the reservoir via horizontal steam injection w

A sediment core taken from the western edge of the Bonneville Basin has provided high-resolution proxy records of relative lake-size change for the period 45.1e10.5 calendar ka (hereafter ka). Age control was provided by a paleomagnetic secular varia

The present study shows the feasibility of preparing hydrocarbon (HC)-depleted cores with a laboratory setup operated at near steam-assisted gravity drainage (SAGD) oil production conditions (200—240 °C and 2.5 MPa). One Athabasca core was selecte

Hydrocarbon group-type analyses are presented in this work for characterization of samples related to the Province of Alberta's abundant bitumen reserves that demand more effective ways of utilization and valorization. The main objective of the study

Adsorption of virgin and thermally cracked vacuum residue from Athabasca bitumen was recently reported, using synthetic macroporous kaolin as adsorbent. Following that work, this study addressed the adsorption properties of virgin vacuum residue from
