“…More difficult seems to be comparing the facies models proposed for the mixed carbonate-siliciclastic Upper Triassic Antimonio and Vizcaíno terranes of Mexico proposed in [44] and [43], respectively. The Upper Triassic strata in these two terranes are interpreted to have been deposited in a continentally influenced ramp setting where the moderate to high siliciclastic input might have played a fundamental role in influencing the carbonate sedimentation.…”

“…With the objective of closing this knowledge gap, the REEFCaDe (REEF and Carbonate Development) scientific project was launched at the University of Geneva fourteen years ago. Over this timeframe, various Upper Triassic Panthalassan localities were investigated in the Russian Far East [17,21], Japan [18,[22][23][24][25][26][27][28][29][30], the United States [30][31][32][33][34][35][36][37][38][39][40][41], Mexico [42][43][44] and Canada [45][46][47]. Several aspects of the taxonomy, paleoecology, stratigraphy and distribution of diverse organisms in Panthalassa, including foraminifera (e.g., [26,30,[35][36][37][38][39][40]46]), calcareous algae [48], ostracods [47], halobiid bivalves [41,45] and reef biota [22], have been clarified in the framework of this long-term effort.…”

Upper Triassic carbonate platforms from the Panthalassa Ocean remain less-understood and less-studied than their Tethyan equivalents. This imbalance is largely due to the poorer preservation state of Panthalassan carbonate rock successions in terms of rock quality and depositional geometries, which prevents good appreciation of depositional systems. In this context, carbonate exposures from Lime Peak (Yukon, Canada) represent an outstanding exception. There, the remains of an Upper Norian Panthalassan carbonate platform are well-exposed, show remarkably preserved depositional geometries and overall superior rock preservation. In this work, we analyse the carbonates from the Lime Peak area with particular attention to the vertical and lateral distribution of biotic assemblages and microfacies at the platform scale. Results demonstrate that the Lime Peak platform was surrounded by a basin with an aphotic sea bottom. The carbonate complex developed in warm waters characterized by high carbonate saturation. The area was also defined by moderate to high nutrient levels: this influenced the type of carbonate factory by favouring microbialites and sponges over corals. During its growth, Lime Peak was influenced by tectono-eustatism, which controlled the accommodation space at the platform top, primarily impacting the internal platform environments and the stability of the slope. Gaining better knowledge of the spatial distribution and dynamics of Upper Triassic organisms and sedimentary facies of Panthalassa in relation to tectono-eustatism lays the first foundations for reconstructing more robust platform models and understanding the evolution of other, more dismantled Upper Triassic Panthalassan carbonate systems through time.
