We have applied correlative microscopy to identify the key constituents of a dorsal rib fossil from Koreanosaurus boseongensis and its hosting mudstone discovered at the rich fossil site in Boseong, South Korea, to investigate the factors that likely contributed to diagenesis and the preservation of fossil bone. Calcite and illite were the commonly occurring phases in the rib bone, hosting muds...

To determine background radiation levels that might influence experiments, we measured in situ gamma-ray emissions at ten locations in the Boulby Underground Laboratory. For gamma radiation in the energy range of 7-2,734 keV, the counts varied from 6.5 to 28 γ s-1. For measurements inside the Lab, the arithmetic mean was 24 γ s-1. The sedimentary rocks that surrounded the Lab, halite and mudsto...

The Sample Analysis at Mars (SAM) instrument on board the Mars Science Laboratory Curiosity rover is designed to conduct inorganic and organic chemical analyses of the atmosphere and the surface regolith and rocks to help evaluate the past and present habitability potential of Mars at Gale Crater. Central to this task is the development of an inventory of any organic molecules present to elucid...

Mudstones make up the majority of the geological record. However, it is difficult to reconstruct the complex processes of mud deposition in the laboratory, such as the clumping of particles into floccules. Using flume experiments, we have investigated the bedload transport and deposition of clay floccules and find that this occurs at flow velocities that transport and deposit sand. Deposition-p...

Determining the physical and mechanical behavior of sedimentary rocks is one most common challenges in deep rock mass engineering. Experiments were con-ducted to study properties coal measure mudstone with SEM, XRD, uniaxial compression testing. The results show that temperature has a significant effect on mudstone. presence clay minerals evaluated contributes unique characteristics seen at hig...

Lacustrine mudrocks are composed of minerals and organic matter (OM). The origin preservation OM two controlling factors the hydrocarbon generation capacity mudrocks. It is a key method in source rock research to study deposition process from view sedimentary environment. Following this idea, reason for discrepancy production between northern southern part Dongpu Sag analyzed discussed. lacustr...
