The osseous artifacts from the penecontemporaneous
deposits associated with the Lower Magdalenian human burial at the rear of the El Miron vestibule have been published by Fontes et al.
After the deposition of carbonate sediments, it went through the penecontemporaneous
stage, the early, the middle, and the late diagenetic stage, and the epigenetic stage.
And 3) an unusual association of ironstones, wrinkle structures and vertebrate tracks with microbial mats and penecontemporaneous
iron encrusting allowing track preservation in the sedimentary record.
This variation is due largely to penecontemporaneous
faulting and localized collapse and growth structures related to evaporite growth and dissolution (Olsen and Et-Touhami 2008), as well as faulting related to loading from, and in rheological contrast with, the overlying North Mountain Basalt during the latest Triassic and later.
2004) and suggest penecontemporaneous
formation of dedolomitic rock in Marinova quarry (sample 3) with its void-filling calcite and calcite fill of sample 1A (Fig.
29) does not crop out within the area of Figure 28, but it is considered to be the source of the granitoid clasts that occur in sedimentary breccia-conglomerates that ate penecontemporaneous
with ore deposition (Thurlow 1981; Stewart 1987).
The Eel Bed of the Kokomo Limestone contains sedimentary structures that include bird's-eye (fenestrate) structures, algal mats, gypsum/anhydrite blebs and pseudomorphs, penecontemporaneous
dolomite, and intraformational storm tide deposits, that we interpret as indicative of a supratidal (Shinn 1983; Hardie & Shinn 1986) depositional environment.
The preservation of mimetic fabrics (or textures) of primary sediments suggests they could have been formed either by microbial mediation, particularly for those microbial dolomites (Figures 7(a) and 7(b)) during deposition , or by penecontemporaneous
dolomitization driven by reflux of more saline seawater in the protected lagoon through the ooidal shoal-microbial reefs on the platform margin [25, 38] (Figure 7(c)).
The above-mentioned characteristics indicate that dolostones may result from penecontemporaneous
dolomitization of lime mud on supratidal flat (sabkha) environments by high saline seawater.
In contrast to the Stirling belt, volcanic and plutonic rocks in East Bay Hills, Coxheath Hills, and Sporting Mountain belts are demonstrably penecontemporaneous
at about 620 Ma (Bevier et al.
