... a fault contact between the Esmeralda beds and the older rocks, for it passes within a few feet of a limestone outcrop near the north end (Fig. 7), and porphyritic granodiorite was found in the banks of the wash about 200 feet east of the center of the rift. The average trend of the southern 1,400 feet...

...) was confirmed by subsequent discoveries. Because the upper part of the LMWCF contains Treptichnus pedum (Seilacher), the Ediacaran–Cambrian boundary has long been drawn at its first appearance. However, in the Esmeralda Member of the Deep Spring Formation in the White-Inyo Mountains, California, and at Mount...

... is found in the Paja area, on the right bank of a small creek, about 550 meters southwest of the village, Secal (Guayaquil co-ordinates: north 72.9 km; west 78.2 km). The list of provisional determinations follows. Anomalina sp. sp. (2 species) Bolivina incrassata Reuss Bolivina sp. cf...

..., 1990 ; Dengo and Covey, 1993 ). The Mugrosa Formation conformably overlies the Esmeraldas Formation in the La Cira-Infantas oil field locality. Its lower part, known operationally as the “C sandstones” in the subsurface of the La Cira-Infantas field, does not crop out in this area ( Dickey, 1992...

... as the Chocó (it is likely that the Esmeraldas region, currently in Ecuador, was considered part of the Chocó in the 18th century; Codazzi, 2002 ). Platina and gold have similar specific gravities and in these alluvial deposits, they exhibit similar grain sizes (McDonald and Hunt, 1982 ) and occur mixed...

... Code were made in 1976 after the small M w  6.6 Esmeraldas City interface earthquake, and a single seismic zone was adopted for the country. Several PSHA academic studies were performed in the 1990s (e.g., Bonilla et al. , 1992 ) but the results were not used for establishing zoning. In 2001...

... was prepared ( Figure 4 ) using methods outlined by Dahlstrom (1969) , Roeder and Weller (1982) , Suppe (1983) , and others. To further constrain the subsurface geometry of the triangle zone, the models of Jones (1982) , Price (1986) , and Banks and Warburton (1986) were examined. Restored sections...

... ( Glover, 1971 ; Erikson et al. , 1990 ). Near the south coast, the 2‐km‐wide fault zone is bounded by two principal faults: the Río Jueyes fault on the northeast and the Esmeralda fault on the southwest (Fig.  3 ). On the basis of an offset fold in Cretaceous rocks, Glover (1971) interpreted about 10...

... along the banks of Rio Gamboa, especially in a deep canyon near the hydroelectric center. The metamorphic rocks are mainly mica schists contorted by mierofolds and containing nodular injections of quartz. The contact between the metamorphic rocks and the younger rocks is covered in almost all parts...

... Limestone in the Split Mountain area has a total thickness of ~224 m (Webster, 2011d ). These formations were deposited on the outer shelf, close to the shelf edge and slope (Webster, 2011d ). Similar outer shelf deposits crop out elsewhere in Esmeralda County (Stewart, 1970 ; Albers and Stewart...

... volcanogenic sedimentary deposits ( Honnorez et al., 1973 ), although small mounds and chimney-like structures containing sulfides also occur ( Valsami-Jones et al., 2005 ). Examples of such vent sites include those in 60-to 110-m water depth at Esmeralda Bank in the Mariana arc ( Puteanus et al., 1990...

... ). Previous work has found that these bioherms are in situ accumulations of Renalcis -group microbes and three genera ( Archaeocyathus , Syringothalamus , and Palmericyathellus ) of archaeocyaths ( Fig. 3 B; Xiaoping 1995 ). The bioherms here have previously been interpreted as a brief carbonate bank...

In the central and highest parts of the peninsula of Las Tumbes and the Tetas hills, the morphology consists of a chain of long low hills. On the eastern...
