Deep-marine sandstones containing significant (> 10%) detrital mud (silt and clay) matrix have become increasingly recognized, but mostly in drill core or poorly exposed outcrops where details of their vertical and lateral variability are poorly captured. Exceptional vertical and along-strike exposures of matrix-rich and associated matrix-poor deposits in deep-marine strata of the passive margin Neoproterozoic Windermere Supergroup and foreland basin Ordovician Cloridorme Formation, provide an unparalleled opportunity to document such characteristics. In both study areas, strata form a 100s m long depositional continuum that at its upflow end consists of thick-bedded matrix-poor sandstone (<20% matrix) that transforms progressively downflow to medium- to thick-bedded muddy sandstone (20 – 50% matrix) to medium-bedded bipartite facies with a basal sandy (30 – 60% matrix) part overlain sharply by a muddier part (40 – 80% matrix), and then to thin-bedded sandy mudstone (50 – 90% matrix). This depositional continuum is then overlain everywhere by a thin- to very thin-bedded traction-structured sandstone and/or silty mudstone cap. This consistent lithofacies change is interpreted to reflect particle settling in a rapidly but systematically evolving, negligibly-sheared sand-mud suspension developed along the margins (Windermere) and downflow terminus (Cloridorme) of a high-energy, mud-enriched avulsion jet. Stratigraphically upward, beds of similar lithofacies type succeed one another vertically and transform to the next facies in the depositional continuum at about the same along-strike position, forming stratal units 2–9 beds thick whose grain-size distribution gradually decreases upward. This spatial and temporal regularity is interpreted to be caused by multiple surges of a single, progressively waning turbidity current, with sufficient lag between successive surges for the deposition of a traction-structured sandstone overlain by mudstone cap. Furthermore, the systematic backstepping or side-stepping recognized at the stratal unit scale in both the Windermere and Cloridorme is interpreted to be driven by a combination of knickpoint migration and local topographic steering of the flows, which continued until the supply of mud from local seafloor erosion became exhausted, the main channel avulsed elsewhere, or a new stratal element developed.

Even two years after the COVID-19 pandemic, the meeting and event industry's efforts must focus on understanding attendees' purchase behaviors and event modality preferences. This study aims to address these factors by using a 2 (Event modality: in-person or virtual) × 6 (six dimensions of perceived value: social value, emotional value, monetary value, functional value, novelty value, and convenience value) between-subject experiment design and a 6 (Six dimensions of perceived value (PV): social value, emotional value, monetary value, functional value, novelty value, and convenience value) x 2 (PV effect on word-of-mouth (WOM) intent and repeat purchase intent (RPI)) between-subject experimental design. Specifically, it applies the perceived value theory in investigating the effects of different value dimensions (social, emotional, monetary, functional, novelty, and convenience) based on attendee event modality (in-person or virtual) and their impact on WOM intent and RPI. The data was collected via Prolific. Different ANOVA and t-tests were conducted. The results suggest that event modality had little bearing on the six dimensions of PV. Results also showed that PV positively impacts WOM intent and RPI.
