Tridymite, a low-pressure, high-temperature (> 870° C) SiO2 polymorph, was detected in a
drill sample of laminated mudstone (Buckskin) at Marias Pass in Gale crater, Mars, by the …

ABSTRACT The Lower Cretaceous presalt section in the Kwanza Basin contains an
excellent petroleum system that includes “synrift” strata (Barremian) overlain by a “sag” …

Stromatolites are abundant in shallow marine sediments deposited before the evolution of
animals, but in the modern ocean they are restricted to locations where the activity of …

Organic-matter pores are considered to be the dominant contributor to total porosity in many
shale reservoirs, and consequently much attention has been paid to investigate the factors …

Fine‐grained sediment (mud) and lithified equivalents (mudrock, mudstone, and shale)
contain components similar to ones in coarser sedimentary materials, albeit of such small …

Organic-rich mudrocks that served as sources for the prolific unconventional system of the
Bakken Formation display pronounced heterogeneity in composition and expulsion …

Detrital grain assemblages in mudrocks establish a key starting condition for the diagenetic
pathways that drive the evolution of rock properties in unconventional petroleum systems …

Abstract The South Oman Salt Basin (SOSB) has been studied extensively for knowledge
concerning the habitat of the enigmatic Ediacaran–Cambrian oils that are produced from …

Abstract The Devonian Woodford Shale and Cretaceous Mowry Shale consist of relatively
deep (below storm wave base) intracratonic basin deposits commonly referred to as “shales” …

Diagenetic models for silt-rich mudstone (siltstone) are less advanced than those for
sandstone and clay-rich mudstone. In addition, the influences of diagenetic processes on …
